PRECAUTIONS
Placement precautions
l l l 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. l 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
l l l l l 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 (5oC 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.
