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

CONNECTINGTO OTHER EQUIPMENT
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 for‘on’,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
.
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
sure it is pushed in firmly.
