Installation

T3I REAR PANEL
① Socket for IEC power inlet line
② Voltage selector switch
③ Remote control input
4 Power On/Standby trigger in
⑤ AM step switch
6 Audio output phono sockets, two pairs
⑦ FM coaxial plug
8 Ground socket (for AM loop aerial)
⑨ AM socket (for AM loop aerial)
POSITIONING THE UNIT
Always place the tuner on a level, firm surface.
SETTING UP THE TUNER
AM STEP SWITCH ⑤
The AM tuning 'step size' needs to be set according to your location. This is done using the switch on the rear panel: set it to 10kHz if you are in North America, or 9kHz anywhere else. This switch also ensures correct reproduction of FM broadcasts for your location.
AM AERIAL
An AM aerial is required to receive AM/Medium Wave radio signals.
An external AM loop aerial is supplied as an accessory. This should be attached to the AM Antenna inputs with one end connected to AM
⑨ and the other to Ground ⑧. It does not matter which way round this aerial is fitted. Rotate the aerial to discover which position gives the best reception.
In areas of weak reception or when the receiver is used inside a steel framed building (such as an apartment building) you can use a wire between 3 and 5 metres long to strengthen reception. Mount this high up outside the building, if possible, and connect one end of this wire to the AM antenna input ⑨ as well as the loop aerial supplied. DO NOT DISCONNECT THE LOOP AERIAL.
FM AERIAL
An FM aerial is required to receive VHF radio signals. An external FM ribbon aerial is supplied as an accessory.
For optimal FM radio reception a roof or loft mounted aerial is advised. For your own safety it is recommended that a roof top aerial is fitted by an experienced contractor. Your Arcam dealer should be able to put you in contact with an aerial installer. A contractor will be able to tune your aerial to the nearest FM transmitter. In an apartment building an aerial system may already be installed. If this is the case you should have sockets in your home marked FM or VHF (do not use those marked TV).
The 'T' shaped wire aerial (dipole design) supplied should give reasonably good reception. Mount this aerial as high up as possible on a wall with the elements positioned horizontally. Try each usable wall of the room to see which gives best reception. Use tacks or adhesive tape to secure the aerial in a T-shape. The tacks should not come into contact with the internal wire of the aerial.
Whether you decide to get an aerial professionally installed or opt to use the supplied aerial it should be connected to the FM Antenna input ⑦ on the rear of the unit.
For use in North America, use an F-type antenna connector; for Europe and other areas, use a female Belling Lee-type coaxial connector.
CONNECTING TO OTHER EQUIPMENT
INTERCONNECT CABLES
Interconnecting cables are not supplied with this tuner. We recommend high quality cables as inferior quality cables will degrade the sound quality of your system. Please contact your Arcam dealer for details of suitable cables. Arcam do not recommend any particular type or brand of interconnect cable.
CONNECTING YOUR TUNER TO YOUR AMPLIFIER
AUDIO OUTPUTS ⑥
Two pairs of identical outputs are provided.
Connect one set to your amplifier's tuner input or any other line-level input using suitable high quality interconnect cables. Ensure that the left and right audio outputs from the tuner are connected to the same left and right inputs on your amplifier.
The second set of audio outputs can be used to connect to a second amplifier set up for 'multiroom' use, or routed to a tape recorder for 'off air' recording.
CONNECTING TO A POWER SUPPLY
WRONG PLUG?
Check that the plug supplied with the unit fits your supply and that your mains supply voltage agrees with the voltage setting switch (115V or 230V) indicated on the rear panel of the unit ②.
If your mains supply voltage is different, switch the voltage selector across using a small screwdriver.
MAINS LEAD
The appliance is normally supplied with a moulded mains plug already fitted to the lead. If for any reason the plug needs to be removed, it must be disposed of immediately and securely, as it is a potential shock hazard when inserted into the mains socket. Should you require a new mains lead, contact your Arcam dealer.
PLUGGING IN
Push the plug (IEC line socket) of the power cable supplied with the unit into the POWER INLET socket ① in the back of the unit. Make sure it is pushed in firmly.
Put the plug on the other end of the cable into your power supply socket and switch the socket on.
CUSTOM INSTALLATION FEATURES
The T3I has a number of useful features that make it ideal for a custom installation, where the tuner is fully integrated with a specialist control system or operated by a programmable remote control.
REMOTE CONTROL INPUT ③
A rear panel input that receives modulated carrier-based infrared (IR) commands in RC5 format. The input is suitable for connection to a simple IR eye or to an external controller.
Use of this socket disables the front panel IR eye.
TRIGGER INPUT ④
The trigger socket allows the tuner to be remotely switched in and out of standby. The primary front panel POWER switch must be in, 'on', for this mode.
Apply a +12V DC voltage for 'on', the power indicator glows green; 0V for 'standby', the power indicator glows red.
Note that use of this socket requires a 12V signal before the tuner can be switched fully on.
INFRARED (IR) REMOTE COMMANDS
The T31 responds to a set of Philips RC-5 codes in addition to those available on the supplied handset, which is kept simple for ease of use.
Advanced programmable control devices, such as the Philips 'Pronto' and other system controllers, can be set up to use the additional codes. Refer to the instructions for your programmable device for details.
A table of IR commands is provided on page 10 of this Handbook.
Using your tuner

FRONT PANEL CONTROLS
Preset Memory buttons ①
Directly select up to 32 preset stations (16 AM, 16 FM). Press briefly for stations 1–8, press and hold for more than one second for stations 9–16.
BAND ②
Selects FM or AM frequency band. The appropriate letters appear on the display.
RDS ③
Switches between RDS modes on FM if RDS is available. See the section 'RDS: Radio Data System'.
MONO 4
Selects mono or stereo output. Stereo is only available on FM radio stations. If a weak station is received in stereo the background hiss can be reduced (and in most cases eliminated) by selecting 'MONO'.
In mono mode, FM muting is suppressed when tuning between stations and the 'FM MUTE' indicator is switched off.
STORE 5
The STORE button allows you to assign radio stations to preset numbers. See the instruction 'Storing a preset'
Preset indicator 6
Indicates the number of the preset currently selected.
Signal strength ⑦
A seven-step indicator shows the strength of a tuned station. Good FM reception and locking onto RDS data generally requires five or more bars.
Tuning 8
Switches between Tune and Preset mode for the down/up buttons. Preset mode is indicated by PRESET on the display.
Tune down/up ⑨
Used to either scroll through presets, or to tune up and down the broadcast band, depending on the current mode. See 'Tuning to a station' for more details.
Frequency/ RDS display 10
Indicates the frequency of the selected station in MHz (FM) or kHz (AM); it also displays RDS information when present.
POWER 11
Switches the mains power to the unit on or off.
Power indicator 12
This glows green to show that the unit is ready for use. The indicator glows red in standby mode when the tuner is switched off via the remote control, or configured in a custom installation.
OPERATION
The T31 radio tuner can be controlled from the front panel buttons or from the remote control handset (see 'Using the remote control').
TUNING TO A STATION
Pressing the TUNING button toggles between the two tuning modes of the unit – 'Preset' or 'Tune'. The selected mode is briefly shown in the display.
PRESET MODE
In Preset mode, press the ▲ or ▼ buttons on the front panel (or < or > on the remote control handset) to cycle up and down the preset stations.
See 'Storing a preset' and 'Deleting unused presets', below.
TUNE MODE
Automatic tuning:
Press the ▲ or ▼ buttons on the front panel (or < or > on the remote control handset) for longer than one second to engage automatic tuning. The tuner searches for a radio station signal of sufficient strength and stops. To skip to the next station, press one of the buttons again. Automatic tuning is available for both the FM and AM bands.
Manual tuning:
Tap the ▲ or ▼ buttons for manual tuning. This can be used for tuning to a specific frequency. It is also useful if you are trying to select a station that is too weak for the auto search mode.
Regardless of the mode used to tune your T31, when it is accurately tuned to a station 'TUNED' lights up in the display.
STORING A PRESET
To store a preset, tune to the radio station you wish to store. Press the STORE button: this causes 'PRESET STORE' to flash in the display. Now select the preset number you wish to assign to the station using the preset memory buttons or the ▲ and ▼ buttons on the front panel. Press the STORE button again.
Once the preset is stored, the display reverts to show the station name (if RDS information is transmitted) or its frequency.
To quit the memory function without storing a preset, leave the tuner controls untouched for ten seconds. It is also possible to overwrite a stored station by saving another in its place. There are thirty presets available for FM use and sixteen for AM use.
Your presets are retained when the T31 is disconnected from the mains supply.
DELETING AN UNUSED PRESET
Press the RDS and STORE buttons on the front panel, wait about three seconds, then select the preset number you want to delete using the ▲ and ▼ buttons, followed by the RDS button.
The display briefly shows 'DELETED' and '-' is shown in place of the preset number. You can reactivate a deleted preset number by storing a station in the normal way.
RDS: RADIO DATA SYSTEM
The Arcam T31 supports RDS Programme Service and RDS Radio Text on FM broadcasts.
When a station carrying RDS information is selected 'RDS' lights up in the display and shortly afterwards the station's RDS name (e.g. 'BBC R3') is shown.
Press the RDS button to view any RDS text information (if a station is not transmitting text information, the display briefly indicates 'NO TEXT' and reverts to show the station name).
Press RDS again to display the station's frequency.
Pressing RDS a third time returns you to a display of the station name.
If the RDS button is pressed while tuned to a non-RDS station, the display shows 'NO NAME' for three seconds before reverting to the default display.
ENTERING STATION NAMES MANUALLY
Station names can be entered and saved for preset AM stations, and for FM stations where RDS is not available. Station names can be up to eight characters long.
First select the band and the preset station you wish to name. Then press and hold the RDS button for more than two seconds. An 'underscore' line should appear blinking in the first position of the frequency display area. Use the ▲ and ▼ buttons beneath the display to scroll through the available alphabet, numbers and special characters available until you reach your wanted letter or character. Press the TUNING button to confirm that character. The 'underscore' line will then move to the next position. Repeat this process to enter the required name. If you want to edit a character later, use the
TUNING button to step along and select it, then use the ▲ and ▼ keys as before to change it. When complete, press STORE to enter the name into the preset memory.
Using the CR-389 remote control

NOTE: DAB (Digital Audio Broadcast) refers to Arcam DAB tuners such as model DT81.
NOTE: Remember to install the two AAA batteries supplied before trying to use your remote control.
Do not place anything in front of the display area on the tuner (where the IR receiver is located), or the remote control may not work.
