CONNECTIONS AND INSTALLATION

■ Power source

The transceiver requires a regulated DC power of
13.6 V and at least 60 A or 26.4 V and at least 30 A,
depending on the transceiver version.
Directly connect to a 12 V or 24 V battery in your
vessel through the supplied DC power cable.
CAUTION:
• DO NOT reverse the DC power cable polarity.
This could damage the transceiver.
• BE SURE to use a 12 V or 24 V battery,
depending on the transceiver version.

■ Antenna

Most stations operate with a whip or long wire antenna.
However, these antennas cannot be connected directly
to the transceiver because their impedance may not
match the transceiver antenna connector.
