NOTES: • ALWAYS TURN THE TV/DVD TO “OFF”
BEFORE SWITCHING THE IGNITION OF
THE CAR ENGINE.
• Make sure that the negative terminal of the
battery is grounded.
This set is designed for use with negative
grounding systems only.
• Use the supplied car cord only.
• When the TV/DVD is not in use, always discon-
nect it from the car cigarette lighter socket to
avoid a battery drain.
• If the TV/DVD 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/DVD 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/DVD is used in a vehicle.
REPLACING THE FUSE IN THE CAR
BATTERY CORD PLUG
If the fuse in the car battery cord plug blows, replace
it with a new 8 A fuse (Fast Blow Type) as shown

TIP
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, fol-
low the instructions below that correspond to your
antenna system. If you are using a cable TV service
(CATV), see page 13 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
Combiner to the Antenna Jack.
Connect the 75 ohm cable from the combination VHF/
UHF antenna to the Antenna Jack.
If your combination VHF/UHF antenna has a 300 ohm
twin-lead wire, the use of the 300-75 ohm Matching
Transformer may be necessary.
