Installing the radio
1.
Cut the proper-sized hole in your dash.
2.
Pass any cables through the hole, then insert the radio until the mounting
flange is flush with the dash.
3.
Use the screws and washers to attach the right angle brackets to
the radio as shown.
4.
Thread the lock nuts onto the stove bolts; turn them until they move up close
to the bolt head.
5.
Place the flat bracket against the dash and align the dimples with the holes in
the right angle bracket.
6.
Insert the bolts through the right angle bracket and into the dimples on the
flat bracket, then tighten the bolts securely. Move the lock nuts down the bolts
until they touch the bracket.
7.
Use pliers or a wrench to tighten the lock nuts against the bracket.
8.
Repeat this procedure with the other right angle bracket.
Connecting the radio
To operate correctly, your radio requires 2 electrical connections to:
•
provide it with power from the boat’s electrical system, and
•
connect a VHF-FM marine antenna to the antenna connector.
Power Supply Requirements
VHF Antenna Requirements
-
Nominal 13.8 VDC power supply with a negative ground (10.4
VDC to 15.8 VDC).
-
Power leads should be kept as short as possible. A direct
connection to the power supply is ideal.
-
Minimum of #14 AWG copper wire for extensions up to 20 feet,
12 AWG wire for extensions from 20 to 35 feet, or 10 AWG wire
for extensions from 35 to 60 feet.
-
Male PL-259 connector
-
50 Ω impedance
-
Minimum 4 foot, 3 dB rated antenna for sailboats or 8 foot, 6dB
rated antenna for powerboats
-
Minimum RG-58 lead-in wire for antenna leads up to 20 feet,
RG-8X for antenna leads from 20 to 35 feet, or RG-8U for
antenna leads from 35 to 60 feet.

NOTE: To extend the life of the radio, use waterproof tape to seal electrical connections.
1.
Install your antenna according to the manufacturer’s instructions.
2.
Be sure there is enough distance between the antenna and any occupied areas.
- The FCC recommends that antennas up to 3 dB be installed a minimum of 3 feet from any occupied location;
antennas over 3 dB should be installed at least 6 feet away. If necessary, consult the FCC guidelines for antenna
separation.
3.
Connect the PL-259 connector from the antenna lead-in wires to the SO238 connector labeled
ant
on the back of your
radio.
