3. When charging your vehicle battery, or when jump-

disconnect the
power cable from the back of the transceiver, or
damage may result to the transceiver.
Connect the TS-440S/44X power cable to the bat-
tery terminals, with consideration to current re-
quirements and noise prevention. The maximum
current drawn by the TS-440S/44X reaches to be-
tween 18 and 20A when transmitting. Therefore,
the cable should be made as short as possible, us-
ing the specified fuse. Also, determine that the
power system of the car (including the battery and
generator or alternator) will handle the increased
load of the TS-440S/44X.
