3. ATTACH THE ANTENNA CABLE TO THE RADIO
A suitable antenna must be mounted in a safe location and connected to the radio base
station before turning on the radio. A very important factor affecting the performance
of any radio communication system is the selection of a suitable antenna. Consult your
dealer about antennas and ask them to help you select a suitable antenna for your
radio. Refer to the following guidelines for best results.
For optimal radio performance and to minimize human exposure to Radio Frequency (RF)
and Electromagnetic Energy (EME), make sure the antenna is:
Connected to the radio before powering up the radio.
Properly mounted according to the antenna manufacturer’s recommendations.
Located at least three feet (one meter) from people while it is transmitting.
Located at least 3.3 feet (1 meter) from the radio base station transceiver and
microphone handset.
• Using a standard PL259-type (UHF-type) connector.
WARNING: Failure to comply with the above requirement may expose those closer than the
recommended boundaries to absorb enough RF radiation to exceed the Maximum Permissible
Exposure (MPE) limit defined by the FCC. It is the responsibility of the radio operator to make
sure that both the radio operator and any other people in the vicinity of the radio comply with
MPE limits while the radio is transmitting.
4. INSTALL THE MICROPHONE MOUNTING BRACKET
Find a location near the base station for the microphone mounting bracket. The distance
between the base station and the microphone mounting bracket should be shorter than
the length of the microphone cable.
CAUTION: Keep the radio base station and microphone at least 3.3 feet (1 meter) away from
any magnetic devices on your boat (such as a compass).
1. Place the microphone mounting bracket on the surface where you want to
attach it, and use a pencil to mark the location of the two mounting holes on
the mounting surface.
CAUTION: Before drilling, make sure that there is nothing behind the mounting surface that
might be damaged while drilling the mounting holes. Also, if the back side of the mounting
surface is inaccessible or difficult to reach then you should probably use the supplied self-
tapping screws instead of the supplied mounting nuts and bolts.
