Power Supply
Do not force the unit’s power-supply cord to share an outlet with an unreasonable number of other devices.
Be especially careful when using extension cords-the total power used by all devices you have connected to the extension
cord’s outlet must never exceed the power rating (watts/amperes) for the extension cord. Excessive loads can cause the
insulation on the cord to heat up and eventually melt trough.
The unit and the AC adapter should be located so their location or position does not interfere with their proper ventilation.
Always grasp only the plug on the AC adapter cord when plugging into, or unplugging from, an outlet or this unit.
At regular intervals, you should unplug the AC adapter and clean it by using a dry cloth to wipe all dust and other
accumulations away from its prongs.
Also, disconnect the power plug from the power outlet whenever the unit is to remain unused for an extended period of
time. Any accumulation of dust between the power plug and the power outlet can result in poor insulation and lead to fire.
Try to prevent cords and cables from becoming entangled. Also, all cords and cables should be placed so they are out
of reach of children.
Never climb on top of, nor place heavy objects on the unit.
Never handle the AC adapter or its plugs with wet hands when plugging into, or unplugging from, an outlet or this unit.
Before moving the unit, disconnect the AC adapter and all cords coming from external devices.
Before cleaning the unit, turn off the power and unplug the AC adapter from the outlet.
Whenever you suspect the possibility of lightning in your area, disconnect the AC adapter from the outlet.
Keep any caps you may remove and the included wing bolts in a safe place out of children’s reach, so there is no
chance of them being swallowed accidentally.
Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter
(such as a refrigerator, washing machine, microwave oven, or air conditioner), or that contains a motor.
Depending on the way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may
produce audible noise.
If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the electrical outlet.
The AC adapter will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.
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
Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference.
This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.
Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit.
Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you
should relocate such wireless devices so they are at a greater distance from this unit, or switch them off.
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 temperature extremes. Excessive heat can deform or discolor the unit.
When moved from one location to another where the temperature and/or humidity is very different, water droplets
(condensation) may form inside the unit.
Damage or malfunction may result if you attempt to use the unit in this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation has completely evaporated.
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 benzene, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.
