PRECAUTIONS
Placement precautions
Avoid placing the unit in humid or dusty places, or where it will be exposed to excessive heat
(direct sunlight, heaters, etc.)
Do not step on or set anything on the AC cord.
DAMAGE TO THE AC CORD IS A SAFETY RISK AND CAN CAUSE A FIRE.
Do not connect the unit to the same AC as outlet with appliances that generate large amounts of
interference (such as heaters with thermostats, appliances with motors, etc.). It is best to use a
completely separate electrical outlet.
Keep the unit away from water. If water accidentally enters the unit, unplug the AC power cord
immediately. DO NOT PLUG IN THE UNIT AGAIN.
Handling precautions
Avoid bending, kinking or damaging the AC power cord.
Never insert or remove the power cord with wet hands. Also, be sure to hold cord by the plug when
removing it from the outlet.
Do not remove any parts that are held in place with screws. (The unit does not contain any user
serviceable items.)
Maintain standard room temperature (5
o
C to 35 oC, or 41oF to 95 oF) during use. Do not subject the
unit to shock or vibration. Do not move the unit while it is in use.
A rapid increase in room temperature in cool weather can cause condensation to from inside the unit.
If this occurs, wait at least 15 minutes after turning the unit on before attempting to operate it.

PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol in the parts list and the schematic
diagram designate components in whitch safety can be of special significance. When replacing a component identified with use only the replacement
parts designated, or parts with the same ratings of resistance, wattage or voltage that are designated in the parts list in this manual.
Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably insulated from the supply circuit before
returning the product to the customer.
