Mechanical Installation
In most vehicles the producers plan an installation cut-out for the car radio. The choice of the location depends on safety aspects. Therefore we recommend that you actually install the radio in this place.
The radio requires a DIN installation cut-out with the dimensions 182x53mm; these dimensions are standardized and usually the vehicle manufacturers keep to them.
Should there be no slot, please ask your car dealer about the correct place of installation for your car radio.
Please select the place of installation carefully so that the radio neither influences the driver's activity nor distracts him from the traffic.
Only use the supplied installation material to guarantee a safe installation.
Any changes in the vehicle that become necessary for the installation of the SD tuner or other components, must be carried out in such a way that neither the traffic security nor the stability of the car are affected. With many cars, the type approval will lapse if you merely saw out a section of the sheet metal.
Since the radio creates heat during operation, the place of installation must be heat-resistant.
Make sure before drilling the attachment holes that no electric cables, brake lines, the fuel tank or similar are damaged.
When using tools to install your car hi-fi components, observe the manufacturer's safety instructions.
When installing the car hi-fi system, take into consideration the risk of accident which can arise from devices being torn away in the case of an accident. Therefore, you should secure every component in a place where it cannot be dangerous to passengers.
Before you install the system, check the depth of the installation recess.

Installation in the radio slot
text_image
1 2 1 2 182mm 53mm 3 4- Unlock the installation frame with the two unlocking keys (fig. 1, no. 1).
- Remove the installation frame towards the back of the system (fig. 1, no. 2).
- Insert the frame into the respective cut-out in the vehicle (fig. 2).
- Bend down some clips in the installation frame until the frame is securely fastened in the recess.
- When you have made all the electrical contacts (see "Electric Connection") insert the radio into the frame until it locks in (fig. 4).
Keep the two unlocking keys. You will need them for later removal of the radio.
- Protect your radio against vibrations with the bolt at the back of the unit.
- In most vehicles, such a safety fastening is provided for. If this is not the case in your car, fasten the radio with the enclosed punched metal strip.
For the fastening, proceed as follows.

The electric connection should be done by a specialist.
To avoid short-circuits and resulting damage to the radio, the negative pole (earth) of the vehicle battery must be disconnected during connection.
Only connect the negative pole of the battery, when you have completely connected the system and checked the connections.
You should only use a voltmeter or a diode test lamp for checking the voltage on the on-board cables as normal test lamps consume excessive currents and can thus damage the electronic system of the car.
When laying the cables, make sure that they are not squeezed or scoured on sharp edges. Use rubber grommets for the feed-though points.
The line towards the loudspeakers must be a bifilar cable. Insulate the bare wires at the connecting terminals. Ensure there are no sharp edges which could damage the cables.
Only use loudspeakers which have a sufficiently high loading capacity (see "Technical Data").
Make sure that all loudspeakers have the correct polarity, i.e. the plus and minus signs must match.
The connecting cables of the loudspeakers are usually coded: Some loudspeaker manufacturers indicate the (+) wire by means of an additional colour stripe, others use a corrugated cable for the (+) terminal and a smooth one for the (-) terminal.
The system was designed for the operation at loudspeaker impedances of at least 4 Ohm. Never connect loudspeakers with a lower impedance.
In most vehicles the cables for the electric connection and the connection of the loudspeakers have been laid directly to the installation slot.
If this is not the case, please make sure that any cables placed later are secured by the respective onboard fuses (see vehicle operation manual).
Connecting the aerial
- Connect the aerial plug of your vehicle with the aerial socket at the back of the radio (socket next to the Cinch terminals).
- If your vehicle has a different aerial plug, please use a suitable adapter, available in specialist shops.
Connecting the LINE outputs
The SD tuner has four LINE outputs for connecting a power amplifier.
For the connection of the cinch sockets only use the shielded cinch wires. The use of other cables might cause interferences.
Keep the distance of the cables as short as possible.
Do not place the cables near other cables to avoid interferences in the cables.
To avoid distortions or mismatches that could damage the unit, the cinch connector must only be connected to devices with the suitable cinch terminals. For this, observe also the connection data in the section "Technical Data".
- Connect the Cinch sockets on the back of the radio to the power amplifier's input.
The red socket is a terminal for the right channel
The white socket is a terminal for the left channel
AUX IN connection
You can connect an external audio device (e.g. portable MP3 player) to the port AUX IN (22) whose signal is played back via the vehicle loudspeakers.
- Connect the port AUX IN (22) with the audio output of the external device.
Connection of the loudspeakers and the power supply
Vehicles equipped with such an ISO system plug can be connected directly to the ISO terminal if the plug assignment is the same (please check beforehand!). If the plug assignment is not the same then it is connected via an adapter specific to the vehicle, which is available in shops.
Please refer to the following illustrations for the SD tuner's ISO connection socket contact assignment.
Please ask you car dealer for the respective assignment of your vehicle system plug.

- The constant current terminal +12V (4) must be connected to a cable that also supplies 12V permanently when the ignition is off (terminal 30 of the on-board network). This terminal serves to save the user settings, time, etc.
- The aerial control output (5) supplies a voltage of +12V when the device is switched on. This cable can be used for the power supply of an electrical aerial, and for the voltage for switching on a vehicle amplifier.
- The terminal of the ignition +12V (7) must be connected to a cable that is only live with +12V when the ignition is on (terminal 15 of the on-board networks).
Do not connect this terminal to continuous current, otherwise the on-board battery could be discharged when the vehicle is parked for a longer period of time.
- Connect the ground connection (8) with the vehicle body.
Adhesive techniques which become ever more common and painted metal parts impair the electric conductivity. Therefore not every metal part is a suitable earthing point.
Do not turn on the device before you have read and understood these operating instructions.
Check all the connections again. When you have done so, reconnect the negative pole of the car battery.
General operation
- Button (1)
This button switches the radio on and off.
- MODE button (10)
With this you can select various audio sources.
Every time the button is pressed, the radio switches to the next source:
TUNER > USB > SD-MMC > AUX
When one of the sources is not active, i.e. no medium inserted, this source will be skipped in the selection.
• VOLUME control / SELECT button (3)
In standard operation, the VOLUME control is for setting the volume.
Press the SELECT button once or several times, to change the parameters BAS (bass control), TRB (treble control), BAL (balance control) and FAD (fader control) by turning the VOLUME control.

Operation
Radio mode
Receiving concept RDS
The abbreviation RDS stands for Radio Data System, i.e. inaudible, additional information codes are transmitted by the FM RDS station.
With the SD-3023 you have an SD tuner that is able to evaluate these coded data that are transmitted by most of the radio stations.
The following important data is transmitted:
- Program Identification (PI)
- Traffic Program (TP)
- Traffic Announcement (TA)
- Program Service (PS)
- Alternative Frequencies (AF)
- Program Type (PTY)
- EON Information (enhanced other networks)
- Clock time (CT)
Program Identification (PI)
These data help the receiver to identify a station. It enables the radio to differentiate between areas where the same programme is transmitted. The car radio only switches to a stronger station when the reception gets weaker, if the stronger station transmits the same programme identification
Traffic Programme (TP)
This signal enables the receiver to detect that a station with a traffic programme is being received.
Traffic Announcement (TA)
With this signal the receiver can detect a traffic announcement and interrupt the current replay of a different audio source.
Program Service (PS)
This information tells the receiver which station it is receiving. It is directly replayed in the display of the car radio, e.g. BAYERN 3.
Alternative Frequencies (AF)
A list of alternative frequencies that send the same programme is transmitted. If the transmitter station currently received becomes too weak, the receiver detects from the AF signal on which frequencies it must search for a better transmitter.
Program Type (PTY)
This code gives the receiver information about the type of the transmitted programme (e.g. sports, classic, news etc.). The listener can select his favourite programme purposefully.
A national disaster alarm can also be prepared this way. However, not all the radio stations offer the PTY service.
EON Information (EON)
Many chains of radio stations with various programmes only have one programme with traffic information. If EON information is transmitted, a radio equipped with an EON function switches to the Traffic Announcement station whenever such announcements are made, even if a different programme of this chain is being played.
If you listen to Bayern 4 for example (no traffic announcement) and the TA button is activated, the radio will switch to Bayern 3 (with traffic announcements)) for the time of a traffic announcement.
Clock time (CT)
Many stations transmit the current time in the RDS data. If a radio receives this signal, it sets the in-built clock automatically.
Therefore, when you leave the transmission area, the RDS system has the advantage that it switches to a similar transmitter station that can be better received. However, it only changes when it finds a better transmitter station with the same programme.
Short signal attenuations due to the reception cannot be eliminated by the RDS system either, since this would mean that the car radios permanently switches back and forth. The listener would feel much more disturbed by this than by short-term reception problems.
Another advantage of the RDS system is that the station name is displayed. The station name of an RDS station is displayed in the car radio.
Operation
Function of the keys
- BND/LOU/ENT button (4)
With this button you can select the band range of the radio unit.
There are 3 FM ranges and 2 AM ranges available:
$$ F 1 > F 2 > F 3 > M W $$
On each of the four band ranges, 6 stations can be stored on the station buttons 1-6 (16).
- Buttons ◀◀ and ▶▶ (2)
With these buttons the receiving frequency can be changed to adjust stations in radio operation.
Briefly pressing a button starts the automatic station search. (SEARCH is displayed).
The auto-scan only stops at the next station that can be received well.
By pressing a button longer, you activate manual station scan.
The display shows MANUAL.
In this mode, the frequency is changed until you release the corresponding button again. Brief presses of this button changes the frequency step by step.
If buttons are not pressed for a longer period of time, the device switches back to automatic station search. The display shows AUTO.
- Station buttons 1-6 (16)
If you shortly press these buttons, you can select a station you have pre-set.
If you want to store a station you are listening to, simply press the desired button for more than 1 second.
Each of the three FM band ranges (F1-3) and also the AM reception range (MW) has six station buttons. Therefore you can assign 24 station buttons.
Operation
- AS/PS button (8)
If you press this button shortly, the stations stored on the station buttons 1-6 (16) are played for 5 seconds each.
To stop the auto-scan, press the button again.
When you keep the button pressed, all the stations that can be received well are stored on the station buttons 1-6 (16).
After this procedure, the stored stations are played for a few seconds each, as described above.
• TA button (21)
Press the TA button (21) once shortly > TA is activated
Press the button again > TA is deactivated
When you receive a traffic programme station, the display shows TP (traffic programme).
When you keep the TA button pressed, the abbreviation TA is displayed.
If a different audio source is being played (an SD for instance), the programme is set to mute during the traffic announcement.
When you listen to a radio programme at a very low volume, the volume is automatically increased to an easily audible level.
When the traffic announcement is over, the volume you were hearing before is restored.
EON sensitivity setting:
It is possible with this function to make the switching of traffic announcements of other programmes from the same transmission chain dependent on their reception strength.
Press the TA button (21) for about 2 seconds until the display shows EON TA LO or EON TA DX.
When you press the TA button once more, you switch between these two modes.
The normal display reappears automatically after a few seconds.
EON TA LO: The radio only switches to EON traffic announcements if the EON transmitter's signal strength is good and no interference is expected.
EON TA DX: The radio always switches to EON traffic announcements, the signal strength is not taken into account.
Operation
- AF button (7)
Press the AF button (7) once shortly > AF is switched on
Press the button again > AF is switched off
The AF button (7) activates the automatic transmitter station tracking.
"AF" will be displayed.
If the reception of an RDS transmitter station gets weaker or the radio does not receive an RDS station at all, the display flashes.
When a station can be received well, the symbol is displayed continuously.
When you leave a transmission area, the radio can only switch to a better sender when the AF function is activated.
Regional identification:
Press the AF button (7) for about 2 seconds until the display shows REG ON or REG OFF.
When you press the AF button once more, you switch between these two modes.
The normal display reappears automatically after a few seconds.
REG ON: As reception becomes weaker the radio switches to another frequency with exactly the same programme.
REG OFF: As reception becomes weaker the radio switches to another station with the same regional identification.
- PTY button (20)
This button activates the PTY function. You can recognize it by the PTY display.
When pressing the PTY button, the display shows the selected programme type.
Set the programme type you want using the VOLUME control (3) and press one of the buttons ◀◀ and ▶▶ (2), to start the auto-scan.
Now the automatic search for a station with this program type starts.

USB/memory card operation
The radio is equipped with a USB interface and a memory card reader for SD/MMC cards, MP3 files stored on these media can be played.
Do not connect an MP3 player to the USB interface if it is battery operated.
The USB interface power supply can charge the installed batteries and thus lead to overheating or even explosion of the batteries.
USB media and USB hard disks up to max. 40 GB and with power input of max. 1A can be connected to the USB interface.
Only USB storage media can be operated at the USB socket. MP3 players with a USB port usually switch into PC mode when this port is connected. In this mode, music files cannot be played. However you can connection an MP3 player's audio output to the AUX IN port (22) at any time.
SD/MMC cards and SDHC cards up to max. 8 BG are supported.
The media must be formatted in FAT 32.
Due to the great variety of systems with USB and SD/MMC card interfaces and their different functions that are sometimes producer-specific, we cannot guarantee that all media will be recognized and that all the operational functions are available with this radio.
If the storage media is not recognised, then please remove it and plug it in again.
- Connect your USB storage medium with the USB port (23).
- If you use a memory card, insert it into the memory card reader (12).
- The player switches to the respective input automatically and starts replay.

Handling
- If the volume inside your car is too high, you will not hear acoustic warning signals. This constitutes a danger to yourself and other road users. Therefore, make sure the volume is at a suitable level.
- Inattentiveness on the road might involve serious accidents. Operation of the hi-fi system may therefore only take place if the traffic situation permits and you are not unduly distracted by operating the system.
- Do not listen to excessively loud music over an extended period of time. This may damage your hearing.
Maintenance
Regularly check the technical safety of the SD tuner, e.g. for damage of the cables or the housing.
If it can be assumed that safe operation is no longer possible, the device must be turned off and precautions are to be taken to ensure that it is not used unintentionally. Disconnect the car power system!
It must be assumed that safe operation is no longer possible if:
• the device shows visible damage
- if the appliance does not function for some reason, or
• following considerable stress during transportation.
Before cleaning the SD tuner or performing maintenance, the following safety instruction must be observed:
Live components may be exposed if covers are opened or components are removed.
The device must be disconnected from all power sources before any servicing or repair work is carried out.
Capacitors inside the device may still carry voltage even though they have been disconnected from all power sources.
Only qualified experts familiar with the hazards involved and the relevant regulations may perform repairs.
Replacing the Fuse
If it becomes necessary to replace a fuse, make sure that only fuses of the prescribed type and nominal current are used (see "Technical Data").
Never repair fuses or bridge the fuse holder.
- When the power supply has been disconnected (disconnect ISO plug!) carefully remove the fuse from the fuse holder next to the ISO plug.
- Replace it by a fuse of the same type.
- Only then can you re-connect the SD tuner to the electric on-board system.
- Should the fuse trigger again, have the CD tuner repaired in a specialised workshop.
Maintenance
Cleaning
The device should only be cleaned with a soft, dry cloth or brush from the outside.
Never use any aggressive cleaning agents or chemical solutions that may damage the surface of the housing.
Troubleshooting
With the Renkforce SD-3023 SD tuner, you have purchased a product that is equipped with state-of-the-art technology and safe to operate.
Nevertheless, problems or errors may occur.
Therefore, we would like to describe how to eliminate possible faults here:
Please observe the safety notes!
No replay, no display, and the lights are out:
- Faulty car fuse. Look up the respective fuse in the operation manual of your car. Check the fuse.
- The fuse of the SD tuner is defective. Remove the SD tuner and check the fuse.
- The positive line/ground line is loose. Remove the radio and check the cable connections.
Replay only through one speaker:
- The balance control is wrongly adjusted. Adjust the balance control as described.
- The speaker connection has come loose. Remove the radio and/or speakers and check the connections.
Replay only through the front or rear speakers:
- The fader control is wrongly adjusted. Adjust the fader control.
- The speaker connection has come loose. Remove the radio and/or speakers and check the connections.
Troubleshooting
In radio operation hardly any stations can be received:
- The aerial is not pulled out completely. Pull out the aerial to its full length.
- The aerial connection has come loose. Remove the radio and check the connection.
- The aerial is defective. Check the connection, grounding and the aerial itself.
Problems during radio and USB/memory card operation:
- Interferences reach the radio via the positive cable. Install an additional interference suppression coil into the positive line.
- If necessary also equip the vehicle with spark-plug suppressor sockets, distributor arms etc. to suppress interferences.
- Poor earth connection. Check the earth connection and if needs be use another earthing point.
When you press a station button, you only hear hissing:
- No station has been programmed. Program the stations as described above.
The device no longer responds to button commands or displays strange symbols in the display:
- Reset the device using the RESET button (11).
Repairs other than those described above should only be carried out by an authorised specialist.
Disposal
At the end of its service life, dispose of the product according to the relevant statutory regulations.
