Operating precautions

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 keep the radio playing for long periods of time with the engine stopped. Doing so

will drain the battery of its charge 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. Doing so

may result in it being rendered inoperable.
