DETAILED CONTROLS AND GAUGES
Antenna
Before transporting the machine putting it inside a building, stored the antenna to prevent any interference.
Stow the antenna as follows.
1. Loosen antenna mounting bolt (1) and store the antenna at
position (A).
2. After storing the antenna, tighten bolt (1).
Use Radio with Care
To ensure safety, always keep the sound to a level where it is possible to hear outside sounds during operation.
If water gets into the speaker case or radio, it may lead to an unexpected failure, so be careful not to get water
on the equipment.
Do not wipe the scales or buttons with solvent such as benzene or thinner. Wipe with a dry soft cloth. If the dirt
cannot be removed easily, soak the cloth with alcohol.
When the battery is disconnected or replaced, settings for the preset buttons and clock are cleared, so all settings
must be reprogramed.
