the appliance.

2. Water and moisture

The presence of electricity near water can be dangerous. Do
not use the appliance near water – for example next to a
bathtub, washbowl, kitchen sink, in a wet basement or near a
swimming pool, etc.

3. Object or liquid entry

Take care that objects do not fall and liquids are not spilled into
the enclosure through any openings. Liquid fi lled objects such
as vases should not be placed on the equipment.

4. Ventilation

Do not place the equipment on a bed, sofa, rug or similar
soft surface, or in an enclosed bookcase or cabinet, since
ventilation may be impeded. We recommend a minimum

distance of 50mm (2 inches) around the sides and top of the
appliance to provide adequate ventilation.

5. Heat

Locate the appliance away from naked fl ames or heat
producing equipment such as radiators, stoves or other
appliances (including other amplifi ers) that produce heat.

6. Climate

The appliance has been designed for use in moderate climates.

7. Racks and stands

Only use a rack or stand that is recommended for use with
audio equipment. If the equipment is on a portable rack it
should be moved with great care, to avoid overturning the
combination.

8. Cleaning

Unplug the unit from the mains supply before cleaning.
The case should normally only require a wipe with a soft, damp,

lint-free cloth. Do not use paint thinners or other chemical
solvents for cleaning.

We do not advise the use of furniture cleaning sprays or
polishes as they can cause indelible white marks if the unit is
subsequently wiped with a damp cloth.

9. Power sources

Only connect the appliance to a power supply of the type
described in the operating instructions or as marked on the
appliance.

10. Power-cord protection

Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against
them, paying particular attention to cords and plugs, and the
point where they exit from the appliance.

11. Grounding

Ensure that the grounding means of the appliance is not
defeated.

12. Power lines

Locate any outdoor antenna/aerial away from power lines.

13. Non-use periods

If the unit has a standby function, a small amount of current will
continue to fl ow into the equipment in this mode. Unplug the
power cord of the appliance from the outlet if left unused for
a long period of time.

14. Abnormal smell

If an abnormal smell or smoke is detected from the appliance,
turn the power off immediately and unplug the unit from the wall
outlet. Contact your dealer immediately.

15. Servicing

You should not attempt to service the appliance beyond that
described in this handbook. All other servicing should be
referred to qualifi ed service personnel.

16. Damage requiring service

The appliance should be serviced by qualifi ed service personnel
when:

A. the power-supply cord or the plug has been damaged, or
B. objects have fallen, or liquid has spilled into the

appliance, or
C. the appliance has been exposed to rain, or
D. the appliance does not appear to operate normally or

exhibits a marked change in performance, or
E. the appliance has been dropped or the enclosure

damaged.

Safety compliance

This product has been designed to meet the IEC 60065
international electrical safety standard.

Positioning the unit

Always place the tuner on a level, fi rm surface.

Setting up the aerials

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 fi tted 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 my 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 4 on the rear of the unit.

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
matter which way round this aerial is fi tted. 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

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.

Connecting your tuner to your amplifi er

Audio outputs

Two pairs of identical outputs are provided.
Connect one set to your amplifi er’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 amplifi er.

The second set of audio outputs can be used to connect to a
second amplifi er set up for ‘multi room’ 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 fi ts your supply and
that your mains supply voltage agrees with the voltage setting

(115V or 230V) indicated on the rear panel of the unit 1.
If your mains supply voltage or mains plug is different,

consult your Arcam dealer or Arcam Customer Support on
[phone].

Mains lead

The appliance is normally supplied with a moulded mains plug
already fi tted 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 2 in the back of the unit.

Make sure it is pushed in fi rmly.
Put the plug on the other end of the cable into your power

supply socket and switch the socket on.
