Caution
The heat sink can get hot enough to cause a burn injury. Allow the unit to cool
before doing any maintenance procedures.
The inherent quality of the solid-state components used in this radio should
provide many years of continuous use. However, take the following precautions
to prevent damage to the radio.

Keep the handsets connected or the jack covered at all times to prevent
corrosion of electrical contacts.

Remove dust from the cabinet with a dry clean cloth. Do not use commercial
cleaners to clean the equipment. Those cleaners can remove paint and
markers.

Check that all cables are tightly fastened. Check the cables for corrosion and
rust. Connect the cables that have loosened. Replace any damaged cables.

Never press and hold the PTT key and talk into the handset to transmit your
voice unless an antenna or suitable dummy load is connected to the radio.

The supply voltage range to the radio must be within 10.8 to 15.6 VDC.

Use only FURUNO-approved accessories and replacement parts.

In the unlikely event of serious problems, please contact your dealer.
