Power Supply: Use of Batteries
• A battery was installed in the unit before it left the
factory. The life of this battery may be limited,
however, since its primary purpose was to enable
testing.
• 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
• This device may interfere with radio and televi-
sion reception. Do not use this device in the vicini-
ty of such receivers.
• 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 temper-
ature extremes. Excessive heat can deform or dis-
color the unit.
Maintenance
• 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.
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
• Use a reasonable amount of care when using the
unit’s buttons, sliders, or other controls; and when
using its jacks and connectors. Rough handling
can lead to malfunctions.
• Never strike or apply strong pressure to the dis-
play.
