ELECTRICAL CONNECTIONS
CAUTION
Reverse polarity battery connections will damage the radio!
Connect the power cord and antenna to the radio. Antenna and Power Supply
connections are as follows:
1. Mount the antenna at least 3 feet (1 m) away from the radio. At the rear of
the radio, connect the antenna cable. The antenna cable must have a PL259
connector attached. RG-8/U coaxial cable must be used if the antenna is 25
feet (7.6 m) or more from the radio. RG58 cable can be used for distances
less than 25 feet (7.6 m).
2. Connect the red power wire to a 13.8 VDC ±20% power source. Connect
the black power wire to a negative ground.
3. If an optional remote extension speaker is to be used, refer to section 6.5
for connections.
4. It is advisable to have a Certified Marine Technician check the power output
and the standing wave ratio of the antenna after installation.

Ferrite Cores
To suppress RF interference that can cause abnormal operation of the transceiv-
er, attach the supplied two ferrite cores as shown in the next page: bigger one
to the accessory connection cable and the DC input cable together, and smaller
one to the PA speaker connection cable and the external speaker connection
cable together. Then snap the two halves of each ferrite core together.
Attach each ferrite core as close as possible to the transceiver body.
Finally, wind some plastic tape around each ferrite core, to prevent vibration
from causing the two halves to split apart.
