Your CobraMarine VHF radio is powered
from the vessel’s 13.8-volt negative ground
direct current electrical system (12-volt
nominal). A 10A fused power connection
lead is provided at the back of the
transceiver.
To Connect To A Power Source:
1. Attach the black (-) wire to a negative
(-) ground.
2. Attach the fused (10A) red power (+)
wire to the positive (+) side of the
power system.
NOTE
This radio will draw up to 8 amps when transmitting at full power.
NOTICES

NOTE
All wiring is best kept as short as possible. If the power leads must be extended,
use a high-quality, marine-grade cable sized for up to 10 amps
of current. To minimize voltage drop, choose a wire gauge as follows:
Length Wire Gauge
Up to 1.5m (4.9ft) 1.6 mils (#14)
Up to 3.0m (9.8 ft) 2.0 mils (#12)
Up to 5.0m (16.4 ft) 2.6 mils (#10)
Up to 6.0m (19.7 ft) 3.3 mils (#8)
