Safety guidelines

Safety instructions

This product is designed and manufactured to meet strict
quality and safety standards. However, you should be aware of
the following installation and operation precautions:

1. Take heed of warnings and instructions

You should read all the safety and operating instructions
before operating this appliance. Retain this handbook for future
reference and adhere to all warnings in the handbook or on
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.

Many of these items are common sense precautions, but for
your own safety, and to ensure that you do not damage the unit,
we strongly recommend that you read them.

Radio interference

The DT81 digital radio tuner is an audio device containing
microprocessors and other digital electronics. It has
been designed to very high standards of electromagnetic
compatibility.

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:

■ Reorient 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

outlets.
If the problem persists contact your Arcam dealer or Arcam
Customer Support on [phone].

Setting up the aerial

Your new Arcam tuner is capable of superb reception but only if
it is receiving a good quality transmission signal.

We recommend that a roof mounted aerial is used where
possible, to ensure the best performance. Use a Band III (multi­element Yagi) array if you are a long way from a transmitter, or
use an omnidirectional or folded dipole aerial if you are close to
more than one transmitter. In the U.K. this should be mounted
with all elements vertical as the transmissions are vertically
polarised. Be sure to use a good quality coaxial cable such as
URM43, CT-100 or similar. For Band III use you can use either
50Ω or 75Ω cable provided it is good quality. Always use 50Ω
cable for L-band use.

If the signal is strong the supplied indoor aerial may be
suffi cient. It should be hung on a wall with both wires fully
stretched out vertically. However there will be many areas
where one DAB ensemble (i.e. a group of stations transmitted
together) is strong and others are weak. An external aerial is
desirable in these cases in order to receive a higher number
of services. If the DAB services in your area are transmitted
on L-band (1.5GHz) then consult your dealer with regard to the
best aerial to use.

NOTE: The supplied indoor aerial is suitable only for Band
III, not L-band. An aerial is not supplied in US or Canada.

There is a small aerial made by Bosch which is suitable for
L-Band and Band III and has been used with good results. The
Bosch part number is: F01DE00144

Aerial input socket

The coaxial cable from the aerial should be fi tted with a 50Ω
BNC plug. Connect this to the aerial socket on the back of this
tuner, turning to lock in place.

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.

Digital outputs

Optical and co-axial digital audio outputs are provided. These
can be connected to an external DAC (Digital to Analogue
Converter) in order to enhance the audio potential of this tuner.

They can also be used to connect this tuner to a digital
recording device (such as a CD-R or Minidisc recorder) for
direct recording.

NOTE: The digital output data includes Serial Copy
Management System (SCMS) codes. This allows you to make
one generation of digital recording but further digital copies
will be prevented.

AM/FM tuner audio input

The audio output from a conventional tuner can be connected
here to save an input on the amplifi er. When this tuner is
switched off or is set to bypass mode, this input is routed
straight to the audio output of this tuner.

Remote control in/out

If you are using this tuner with an amplifi er that also features a
remote bus (such as the Arcam Diva A85 or FMJ A22) you can
connect the REMOTE OUT of the amplifi er to the REMOTE IN of
the tuner using a 3.5mm jack lead.

This allows the tuner to be positioned out of sight while still
offering remote control as commands are passed through the
amplifi er. It can also be used to route control signals for multi-
room use.
