IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 29–31, 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.
304b
• Batteries should always be installed or replaced before connecting any other devices. 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 trans-
formers) 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.
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.
