Your VHF Radiotelephone FM-8500 will perform to the utmost of its ability only if it is operated and maintained in accordance with the correct procedures.
The FM-8500 system consists of a main transceiver unit and two antennas. The transceiver unit contains a VHF transmitter, receiver, and channel 70 watch receiver module. The performance and op- eration are controlled on its front panel. The antenna may be of any type available from FURUNO or market and the recommended type is a vertically polarized non-directional type.
