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 period of time, unplug the power cord. When installing or replacing batteries, refer to “CHANGING THE BATTERY”.

[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.

Do not expose the unit to temperature extremes or install it near devices that radiate heat. Direct sunlight 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 penetrate the unit. In the event of

such an occurrence, discontinue use immediately. Contact qualified service personnel as soon as possible.

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.

[CHANGING BATTERY]

When replacing battery, be sure to insert them correctly (to ensure correct polarity). Remove the battery whenever the unit is to remain unused for an extended period

of time.
