    2. Installation 2-1. Unpacking and Inspection Carefully unpack the unit from the shipping carton to avoid damaging the contents. It is also recommended to keep the carton and the packing materials. In an unlikely case that the unit has to be returned to the factory, the original packing materials should be used. 2-2.

  • Page 12: Transceiver Location

    Transceiver Location Select the mounting location for the transceiver considering the following: ! Though the equipment is spray-proof, prolonged exposure to the environment can shorten its life. It is recommended to install the equipment in the cabin or at least in a shaded place. ! The equipment should be located as near to the power source as possible, and as far apart as possible from any devices that may cause interference such as direction finders, navigation receivers and other onboard electronics.

  • Page 32: Communication Distance

    4-2. Communication Distance The FM-2710 operates on the VHF band assigned for maritime mobile stations (156.025 to 163.275 MHz). The VHF radio wave, unlike LF or HF, propagates like a light ray. Thus communication is only available with another VHF antenna which is above the horizon. This is called line-of-sight.

  • Page 33: Maintenance

    5. Maintenance The FM-2710 is designed to provide years of trouble-free operation. It is, however, recommended to inspect and maintain the following points to minimize the possibility of equipment failure and assure optimum performance. Be sure to disconnect the power cable at the fuse holders before performing any maintenance work.
