14 MAINTENANCE
The inherent quality of the solid-state components used in this transceiver will
provide many years of continuous use. Taking the following precautions will
prevent damage to the transceiver.
• Keep the microphone connected or the jack covered at all times to prevent
corrosion of electrical contacts.
• Never key the microphone unless an antenna or suitable dummy load is
connected to the transceiver.
• Ensure that the supply voltage to the transceiver does not exceed 16 VDC
or fall below 11 VDC.
• Use only FURUNO-approved accessories and replacement parts.
In the unlikely event of serious problems, please contact your dealer.
