If the sound quality decreases and the stereo effect is lost while listening to an FM station

In some areas, adjacent stations may interfere with each other. If this interference occurs, this unit can automatically reduce this interference noise (the initial setting when shipped from the factory). However, in this case, the sound quality will be degraded and the stereo effect will be also lost.

If you do not want to degrade the sound quality and to lose the stereo effect, rather than to eliminate the interference noise, see "To change the FM tuner selectivity" on page 55.

What you can do with RDS EON

RDS (Radio Data System) allows FM stations to send an additional signal along with their regular programme signals. For example, the stations send their station names, as well as information about what type of programme they broadcast, such as sports or music, etc.

Another advantage of RDS function is called “EON (Enhanced Other Networks).” The EON indicator lights up while receiving an FM station with the EON data. By using the EON data sent from a station, you can tune into a different station of a different network broadcasting your favorite programme or traffic announcement while listening to another programme or to another source such as CD.

By receiving the RDS data, this unit can do the following:

  • Tracing the same programme automatically (Network-Tracking Reception)
  • Standby Reception of TA (Traffic Announcement) or your favorite programme
    • PTY (Programme Type) search
    • TP (Traffic Programme) search
    • And some other functions

Tracing the same programme automatically (Network-Tracking Reception)

When driving in an area where FM reception is not good, the tuner built in this unit automatically tune in another RDS station, broadcasting the same programme with stronger signals. So, you can continue to listen to the same programme in its finest reception, no matter where you drive. (See the illustration on the next page.)

Two types of the RDS data are used to make Network-Tracking Reception work correctly — PI (Programme Identification) and AF (Alternative Frequency).

Without receiving these data correctly from the RDS station you are listening to, Network-Tracking Reception will not operate.

JVC KDLX50R - Tracing the same programme automatically (Network-Tracking Reception) - 1

To use Network-Tracking Reception, press and hold TP RDS (Traffic Programme/Radio Data System) for more than 1 second. Each time you press and hold the button, Network-Tracking Reception modes change as follows:

Mode 1 Mode 2 Mode 3

87.5 MHz

FMT 245

AF indicator — — REG indicator

Mode 1

The AF indicator lights up but the REG indicator does not.

Network-Tracking is activated with Regionalization set to "off."

Switches to another station within the same network when the receiving signals from the current station become weak.

Note:

In this mode, the programme may differ from the one currently received.

Mode 2

Both the AF indicator and the REG indicator light up.

Network-Tracking is activated with Regionalization set to "on."

Switches to another station, within the same network, broadcasting the same programme when the receiving signals from the current station become weak.

Mode 3

Neither the AF indicator nor the REG indicator lights up.

Network-Tracking is deactivated.

Note:

If a DAB tuner is connected and Alternative Reception (for DAB services) is activated, Network-Tracking Reception is also activated automatically. On the other hand, Network-Tracking Reception cannot be deactivated without deactivating Alternative Reception. (See page 75.)

The same programme can be received on different frequencies.

Usually when you press the number button, the preset station is tuned in.

However, when the preset station is an RDS station, something different will happen. If the signals from that preset station are not sufficient for good reception, this unit, using the AF data, tunes in another frequency broadcasting the same programme as the original preset station is broadcasting. In case no other station is tuned in, you can also search all receivable frequencies for the same programme. (Programme search) To activate programme search, follow the procedure below.

  • Programme search takes a while.
  • See also "Changing the general settings (PSM)" on page 51.

  • Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.

  • Press ▲▶▶ or ◀◀◀ ▼ to select "P(Programme)-SEARCH."
  • Press + to select "SEARCH ON."

Now programme search is activated.

To cancel programme search, repeat the same procedure and select "SEARCH OFF" in step 3 by pressing –.

Changing the display mode while listening to an FM station

You can change the initial indication on the display to either station name (PS NAME) or to station frequency (FREQUENCY), while listening to an FM RDS station.

- See also "Changing the general settings (PSM)" on page 51.

  1. Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.
  2. Press ▲▶▶ or ◀◀◀ ▼ to select "TUNER DISP (display)."
  3. Press + or - to set to the desired indication ("PS NAME" or "FREQUENCY").

Note:

By pressing DISP, you can also change the display while listening to an FM RDS station. Each time you press the button, the following information appears on the upper part of the display:

→ Station FrequencyPS (Station name) PTY (Programme type)

* Then, the display goes back to the original indication in several seconds.

Setting the TA volume level

You can preset the volume level for TA Standby Reception. When a traffic programme is received, the volume level automatically changes to the preset level.

- See also "Changing the general settings (PSM)" on page 51.

  1. Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.
  2. Press ▲▶▶ or ◀◀ ▼ to select "TA VOLUME."
  3. Press + or - to set to the desired volume.

Automatic clock adjustment

When shipped from the factory, the clock built in this unit is set to be readjusted automatically using the CT (Clock Time) data in the RDS signal.

If you do not want to use automatic clock adjustment, follow the procedure below.

- See also "Changing the general settings (PSM)" on page 51.

  1. Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.
  2. Press ▲▶▶ or ◀◀◀ ▼ to select "AUTO ADJUST."
  3. Press – to select "ADJUST OFF."

Now automatic clock adjustment is canceled.

To reactivate clock adjustment, repeat the same procedure and select "ADJUST ON" in step 3 by pressing +.

Note:

It takes about 2 minutes to adjust the time using the CT data. So, you must tune to the station for more than 2 minutes continuously; otherwise, the clock time will not be adjusted.

What is BBE ^II ?

The BBE ^™ function restores the brilliance and clarity of the original live sound in recording, broadcasts, etc.

When a speaker reproduces sound, it introduces frequency-dependent phase shifting, causing high-frequency sounds to take longer to reach the ear than low frequency sounds. The BBE function adjusts the phase relationship between the low, mid and high frequencies by adding a progressively longer delay time to the low and mid frequencies, so that all frequencies reach the listener's ears at the proper time.

In addition, the BBE ^II function boosts low and high frequencies, which loudspeakers tend to be less efficient in reproducing, through dynamic, program-driven augmentation. When combined with the phase compensation feature, the resulting sound has a clearer, more finely detailed “live” presence.

Each time you press + or – in step 2 on the previous page, the BBE ^II function changes as follows.

BBE 1 BBE 2 BBE 3 BBE OFF

As the number gets higher, the BBE ^II function becomes stronger.

When shipped from the factory, the BBE ^1 function is set to “BBE 2.”

To cancel the BBE ^II function, select “BBE OFF.”

What is Voice Recognition System?

The Voice Recognition System enables the voice command operations — “Speak a word. It will be done.”

This System allows you to operate the receiver by your spoken words with ease and safety. It has ended the risk of searching for push-buttons while you are on the road.

The Voice Recognition System provides you two operation modes — User Word mode and Standard Word mode (for demonstrations). In the User Word mode, you can use two types of commands — Operation Commands and Access Commands.

The Operation Commands (13 in total) are preset by the factory and cover basic operations such as “turning off the power” and “ejecting the CD” (see the Preset Operation Command list on page 32).

On the other hand, the Access Commands must be preset by yourself, and be registered by your own voice. For example, you can preset an Access Command to choose a disc in the CD changer when you say “Pop music.” The Voice Recognition System responds to your command, giving you direct access to the disc. You need to preset what to do and what to speak for the Access Commands.

In the User Word mode, both the Operation Commands and the Access Commands are speaker-dependent. So, they may be any phrase in any language (English, Spanish, even Japanese) as long as they are registered using your voice.

This fact ensures that only you can operate this receiver by your voice.

Just for demonstrations (voice demo — see page 45), there are also preregistered Standard Words (English). In the Standard Word mode, this System allows you to use only 13 Operation Commands.

The Operation Commands are speaker-independent in the Standard Word mode, so the System recognizes and responds to an Operation Command spoken by anyone in English.

JVC Voice Recognition System
User Word modeStandard Word mode (for demonstrations)
Features:• Registration of your voice required before use.• More commands available (13 Operation Commands and 12 Access Commands).• Only your voice can be recognized.• Any language can be recognized.Features:• No registration of commands required before use.• Only 13 Operation Commands available.• Anyone’s voice can be recognized.• Only English can be recognized.

Before using the voice commands

Read carefully the following precautions.

Before you start...

  • Make sure that the voice control unit, voice remote, and microphone are correctly connected. (Refer to the Installation/Connection Manual separately supplied.)
  • Set "VOICE/BEEP" to "VOICE," and "VOICE LANG" to the language you understand (see page 47). This may make the voice command operations easy for you to follow.

Precautions for registering your voice:

- Words you should not use:

  • Similarly-pronounced words: If you register words similarly pronounced for different commands, the Voice Recognition System cannot distinguish the differences and cannot recognize your voice.
  • Too short or too long words: Too short or too long words may be difficult to register. Use the words of adequate length (within 3 seconds).
  • Where to register: Command registration should be performed in as quite a condition as possible with car windows all closed.
  • Timing to speak your voice: Your voice will not be accepted unless the voice navigation "Please speak now," "Please repeat" or "Please speak again" is finished completely.

  • Speak word(s) only while "SPEAK" or "REPEAT" is shown on the display.
    – Pronounce your words in a large, clear voice.

- Keep the ignition turned on during registration: Do not turn on or off the ignition.

Precautions when speaking your commands:

- Your voice commands may not be recognized or executed correctly in the following cases:

  • When road conditions are not good. (For example, you are driving on rough roads.)
  • When car windows are open and surrounding noise is high.

- In the User Word mode: If an operation different from one you have commanded is executed, or if your command is ignored so frequently, try to change and register different words again.

- In the Standard Word mode (for demonstrations): Due to the characteristics of your voice, the Voice Recognition System may fail to recognize your Operation Commands you speak and they cannot be executed correctly. If this happens, use the User Word mode.

Registering your voices for the voice commands

In the User Word mode ("DEMO OFF" — initial setting: when shipped from the factory), you can use 13 preset Operation Commands and 12 Access Commands.

To use these voice commands in the User Word mode, you have to do the following:

To use the Operation Commands;

①Select the User Word mode ("DEMO OFF") (Follow steps 1 to 4 on page 34.)
②Register your voice into each Operation Command (Follow steps 5 to 11 on pages 34 to 36.)

To use the Access Commands;

①Select the User Word mode ("DEMO OFF") (Follow step 1 on page 37.)
②Select an operation to preset into an Access Command (For operations you can store into the Access Commands, see page 37.)
③Register your voice into the Access Command (See pages 38 to 41.)

Registering your own voice for the Operation Commands

In order to use the Operation Commands (see the list on page 32) speaking the commands in the language you speak, record your own voices for the Operation Commands. The unit recognizes and accepts the words you have recorded for the Operation Commands.

Before you start...

  • Set "VOICE DEMO" to "DEMO OFF."
    Without setting it to "DEMO OFF," you cannot record your own voices.
  • Notice the following;
  • You can only use the Operation Command for which you have registered your voice.
  • You can register any word you want; however, if it is too short (ex. "Pops"), the System may not recognize it correctly.

- Refer also to the Instructions supplied with your DAB tuner.

What is DAB system?

DAB is one of the digital radio broadcasting systems available today. It can deliver CD quality sound without any annoying interference and signal distortion. Furthermore, it can carry text, pictures and data.

In contrast to FM broadcast, where each programme is transmitted on its own frequency, DAB combines several programmes (called “services”) to form one “ensemble.”

With the DAB tuner connected with this unit, you can enjoy these DAB services.

Tuning into an ensemble and one of the services

A typical ensemble has 6 or more programmes (services) broadcast at the same time. After tuning into an ensemble, you can select a service you want to listen to.

What you can do more with DAB

Tracing the same program automatically (Alternative Reception)

You can keep listening to the same program

• While receiving a DAB service:

When driving in an area where a service cannot be received, this unit automatically tunes in another ensemble or FM RDS station, broadcasting the same program.

• While receiving an FM RDS station:

When driving in an area where a DAB service is broadcasting the same program as the FM RDS station is broadcasting, this unit automatically tunes into the DAB service.

Note:

When reception switches between DAB and FM, the listening volume level may increase or decrease inconveniently. This change in the volume level results from unequal audio injection levels at broadcaster site, but not from the malfunction of this unit.

To use Alternative Reception

When shipped from the factory, Alternative Reception is activated.

1 Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.
2 Press ▲▶▶ or ◀◀◀ ▼ to select "DAB AF," if not shown on the display.
3 Press + or - to select the desired mode.

- AF ON: Traces the program among DAB services and FM RDS stations — Alternative Reception. The AF indicator lights up on the display (see page 12).

• AF OFF: Deactivates Alternative Reception

Note:

When Alternative Reception (for DAB services) is activated, Network-Tracking Reception (for RDS stations: see page 12) is also activated automatically. On the other hand, Network-Tracking Reception cannot be deactivated without deactivating Alternative Reception.

4 Press SEL (select) again to finish the setting.

Handling CDs

This unit has been designed only to reproduce the CDs bearing the COMPACT and DISC marks. Other discs cannot be played back.

How to handle CDs

When removing a CD from its case, press down the center holder of the case and lift the CD out, holding it by the edges.

• Always hold the CD by the edges. Do not touch its recording surface.

When storing a CD into its case, gently insert the CD around the center holder (with the printed surface facing up).

- Make sure to store CDs into the cases after use.

To keep CDs clean

A dirty CD may not play correctly. If a CD does become dirty, wipe it with a soft cloth in a straight line from center to edge.

To play new CDs

New CDs may have some rough spots around the inner and outer edges. If such a CD is used, this unit may reject the CD.

To remove these rough spots, rub the edges with a pencil or ball-point pen, etc.

Moisture condensation

Moisture may condense on the lens inside the CD player in the following cases:

• After starting the heater in the car.

• If it becomes very humid inside the car.

Should this occur, the CD player may malfunction. In this case, eject the CD and leave the unit turned on for a few hours until the moisture evaporates.

Center holder
JVC KDLX50R - Moisture condensation - 1

CAUTIONS:

  • Do not insert 8cm CDs (single CDs) into the loading slot. (Such CDs cannot be ejected.)
  • Do not insert any CD of unusual shape – like a heart or flower; otherwise, it will cause a malfunction.
  • Do not expose CDs to direct sunlight or any heat source or place them in a place subject to high temperature and humidity. Do not leave them in a car.
  • Do not use any solvent (for example, conventional record cleaner, spray, thinner, benzine, etc.) to clean CDs.

When playing a CD-R (Recordable)

You can play back your original CD-Rs on this receiver.

  • Before playing back CD-Rs, read their instructions or cautions carefully.
  • Some CD-Rs recorded on CD recorders may not be played back on this receiver because of their disc characteristics, and of the following reasons:

– Discs are dirty or scratched.
- Moisture condensation occurs on the lens inside the unit.
- The pickup lens inside the CD player is dirty.

  • Use only "finalized" CD-Rs.
  • CD-RWs (Rewritable) cannot be played back on this receiver.
  • Do not use the CD-Rs with stickers or sticking labels on the surface. They may cause malfunctions.

About mistracking:

Mistracking may result from driving on extremely rough roads. This does not damage the unit and the CD, but will be annoying.

We recommend that you stop CD play while driving on such rough roads.
