5.4 Grounding
While special grounding is not generally required for VHF radiotelephone installations, it
is good marine practice to properly ground all electronic equipment to the ship’s ground
system. The RAY53 can be connected to ground by attaching a wire to one of the screws
on the unit’s rear panel and then to the nearest ship’s ground connection point. The
recommended wire to be used or such grounding is #10 AWG.
RAY53’s cabinet was specially designed and die-cast from aluminum to insure maximum
noise rejection from external sources
