Important Notes
Be sure to use only the AC adaptor supplied with the unit. Other AC adaptors may use a different polarity, or be
designed for a different voltage, so their use could result in damage, malfunction, or electric shock.
Power Supply
@ Before connecting this unit to other devices, turn off
the power to all units; this will help prevent damage
or malfunction.
@ Do not use this unit on the same power circuit with
any device that will generate line noise; an electric
motor or variable lighting system for example.
@ The power requirement for this unit is indicated on
its nameplate (rear panel). Ensure that the voltage in
your installation meets this requirement.
@ Avoid damaging the power cord: do not step on it,
place heavy objects on it, etc.
@ When disconnecting the AC adaptor from the power
outlet, grasp the plug itself; never pull on the cord.
@ If the unit is to remain unused for an extended peri-
od of time, unplug the power cord.
Placement
@
Do not subject the unit to temperature extremes
(eg., direct sunlight in an enclosed vehicle). Avoid
using or storing the unit in dusty or humid areas, or
areas that are subject to high levels of vibration.
@ Using the unit near power amplifiers (or other
equipment containing large power transformers)
may induce hum.
@ This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
@ Do not expose the unit to temperature extremes or
install it near devices that radiate heat. Direct sun-
light in an enclosed vehicle can deform or discolor
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 mild, non-
abrasive detergent. Afterwards, be sure to wipe the
unit thoroughly with a soft, dry cloth.
@ Never use benzene, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
@ Protect the unit from strong impact.
@ Do not allow objects or liquids of any kind to pene-
trate the unit. In the event of such an occurrence,
discontinue use immediately. Contact qualified ser-
vice personnel as soon as possible.
@ Never strike or apply strong pressure to the display.
@ Before using the unit in a foreign country, consult
with qualified service personnel.
@ Should a malfunction occur, or if you suspect there
is a problem, discontinue use immediately. Contact
qualified service personnel as soon as possible.
@ To avoid the risk of electric shock, do not open the
unit or its AC adaptor.
Memory Backup
@ This unit contains a battery which powers the unit's
memory circuits while the main (AC) power is off.
The expected life of this battery is 5 years or more.
However, to avoid the untimely loss of memory
data, it is strongly recommended that you change
the battery every 5 years. Please be aware that the
actual life of the battery will depend upon the physi-
cal environment — especially the temperature — in
which the unit is used. When it is time to change the
battery, consult with qualified service personnel.
@ When the battery becomes weak the following mes-
sage will appear in the display: "E00". Please change
the battery as soon as possible to avoid the loss of
memory data.
