• To ensure safe operation of the machine, always be sure to keep the volume of the

radio down to a level where you can easily hear sounds from outside the machine.

• Do not use the radio for a long time when the engine is stopped. Doing so will drain

the battery and make it difficult or impossible to restart the engine.

• Be careful not to allow water or other liquids to come into contact with the radio.

Otherwise, it may result in malfunction.
