A. Battery connection
Connect the supplied power cable with fuse directly
to the battery terminals. Connecting to the cigarette
lighter socket can cause a poor connection, and ex-
cessive voltage drop.
Caution:
1. When connecting or disconnecting the power
cable to or from the power connector, be sure
that the power switch is always in the ''OFF''
position.
2. Disconnect the transceiver before jump-starting
or before charging the battery.
2. Observe polarity of the cable. The transceiver
operates on 13.8 VDC, negative ground. Bat-
tery polarity must be correct. The power cable is
color coded:
