However, both CD players and DVD players generate RF (radio  
frequency) energy. In some cases this can cause interference with FM  
and AM radio reception. If this is the case, switch the player off or keep  
the player and its connecting cables as far from the tuner and its aerials  
as possible. Connecting the player and the tuner/amplifier to different  
mains sockets can also help to reduce interference.

This product complies with FCC requirements.If the equipment causes  
interference to radio/television reception,which can be determined by  
switching the equipment off and on, the following measures should  
be taken: Re-orientate the receiving antenna or route the antenna  
cable of the receiver as far as possible from this appliance and its  
cabling. Relocate the receiver with respect to this appliance. Connect  
the receiver and this appliance to different mains power outlets. If  
the problem persists contact your Arcam dealer or Arcam Customer

FM AERIAL  
POSITIONINGTHE UNIT  
An FM aerial is required to receiveVHF radio signals. An external FM  
ribbon aerial is supplied as an accessory.  
Always place the tuner on a level, firm surface.  
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).  
SETTING UPTHETUNER  
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.  
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 aT-shape.The tacks should not come into  
contact with the internal wire of the aerial.  
AM AERIAL  
An AM aerial is required to receive AM/Medium Wave radio signals.  
Whether you decide to get an aerial professionally installed or opt  
to use the supplied aerial it should be connected to the FM Antenna  
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  
input  
on the rear of the unit.

and the other to Ground  
this aerial is fitted. Rotate the aerial to discover which position gives  
the best reception.  
. It does not matter which way round  
For use in NorthAmerica,use an F-type antenna connector;for Europe  
and other areas, use a female Belling Lee-type coaxial connector.

8
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

CUSTOM INSTALLATION FEATURES  
The T31 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.  
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.  
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.  
CONNECTINGYOURTUNERTOYOUR  
AMPLIFIER  
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.  
AUDIO OUTPUTS  
6
Two pairs of identical outputs are provided.  
Apply a +12V DC voltage foron’,the power indicator glows green;0V  
for ‘standby’, the power indicator glows red.  
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.  
Note that use of this socket requires a 12V signal before the tuner can  
be switched fully on.  
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.  
INFRARED (IR) REMOTE COMMANDS  
TheT31 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.  
CONNECTINGTOA POWER SUPPLY  
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.  
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

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.
