IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2–4, please read and
observe the following:
Power Supply:
Use of Batteries
301
• Do not use this unit on the same power circuit
with any device that will generate line noise
(such as an electric motor or variable lighting
system).
302
• The AC adaptor will begin to generate heat
after long hours of consecutive use. This is
normal, and is not a cause for concern.
303a
• The use of an AC adaptor is recommended as
the unit’s power consumption is relatively
high. Should you prefer to use batteries,
please use the alkaline type.
304a
• When installing or replacing batteries, always
turn off the power on this unit and disconnect
any other devices you may have connected.
This way, you can prevent malfunction and/
or damage to speakers or other devices.
306b
• Batteries are supplied with the unit. The life
of these batteries may be limited, however,
since their primary purpose was to enable
testing.
307
• Before connecting this unit to other devices,
turn off the power to all units. This will help
prevent malfunctions and/or damage to
speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or
other equipment containing large power
transformers) may induce hum. To alleviate
the problem, change the orientation of this
unit; or move it farther away from the source
of interference.
352
• This device may interfere with radio and
television reception. Do not use this device in
the vicinity of such receivers.
354a
• Do not expose the unit to direct sunlight,
place it near devices that radiate heat, leave it
inside an enclosed vehicle, or otherwise
subject it to temperature extremes. Excessive
heat can deform or discolor the unit.
355
• To avoid possible breakdown, do not use the
unit in a wet area, such as an area exposed to
rain or other moisture.
Maintenance
401a
• For everyday cleaning wipe the unit with a
soft, dry cloth or one that has been slightly
dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild,
non-abrasive detergent. Afterwards, be sure
to wipe the unit thoroughly with a soft, dry
cloth.
402
• Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possibility
of discoloration and/or deformation.
