REPLACING THE FUSE IN THE CAR
BATTERY CORD PLUG

NOTES: • ALWAYS TURN OFF TV/VCR FIRST BEFORE

SWITCH ON OR OFF THE IGNITION OF CAR
ENGINE.

• Make sure that the negative terminal of the

battery is grounded. This set is designed for
use with negative ground system only.

• Use the supplied car cord only.
• When the TV/VCR is not in use, always

disconnect it from the car cigarette lighter
socket to avoid a battery drain.

• If the TV/VCR is to be directly connected to a

12V DC power source, for example, recrea-
tional vehicle (RV) applications, make sure
the power cord is connected after the ignition
switch to avoid battery drain.

• Do not operate the TV/VCR if the car battery

is weak. Peak current from the car alternator
could blow the DC fuse.

• Check the battery’s charge level regularly

when the TV/VCR is used in a vehicle.

If the fuse in the car battery cord plug blows, replace it
with a new 8 A fuse (Fast Blow Type) as shown below.
Unscrew the tip of the plug to remove.

Connect the VHF 75 ohm cable and UHF 300 ohm
twin-lead wire to the Combiner (not supplied). Attach
the Combiner to the Antenna Jack.

If you are using an indoor or outdoor antenna, follow
the instructions below that correspond to your
antenna system. If you are using a cable TV service
(CATV), see page 12 for Cable TV connections.

Connect the UHF 300 ohm twin-lead wire to the Combiner
(not supplied). Connect the VHF 300 ohm twin-lead
wire to the 300-75 ohm Matching Transformer. Attach
the Transformer to the Combiner, then attach the
