Transceiver Location
Select the mounting location for the transceiv er 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 possib le, and as f ar apart as possible
from any devices that ma y cause interf erence such as direction finders , navigation receiv ers and other
onboard electronics.
! The cabinet of the equipment, especially the rear panel, gets warm after a long transmission.
Therefore, provide some space around the transceiver to allow f or circulation of cooling air.
Compass safe distance
Standard: 1.7m
Steering : 0.8m
