Battery precautions
Follow these precautions when using batteries in this remote control:
• Use only the size and type of batteries specified.
• Make sure to follow the correct polarity when installing the
batteries as indicated in the battery compartment. Reversed
batteries may damage the device.
• Do not mix different types of batteries together (such as alkaline
and carbon-zinc) or old batteries with fresh ones.
• If the remote is not to be used for a long period of time, remove
the batteries to prevent damage or injury from possible battery
leakage.
• Do not try to recharge batteries that are not intended to be
recharged. These batteries can overheat and rupture (follow
battery manufacturer's directions).
Connecting to an antenna
When shipped from the factory, the TV/CABLE menu option is set to the
CABLE (Cable Television) mode. If you are not using Cable TV, set this
menu option to the TV position.
If you are using an indoor or outdoor antenna, follow the instructions
that correspond to your antenna system. If you are using a cable
television service, see “Connecting to cable television” on page 6.
Combination VHF/UHF antenna (single 75 ohm
cable or 300 ohm twin-lead wire)
Connecting a combination VHF/UHL antenna with a twin-lead wire:
1 Connect the 75 ohm cable from the combination VHF/UHF
antenna to the RF IN jack.
2 If your combination VHF/UHF antenna has a 300 ohm twin-lead
wire, you may need to use a 300-75 ohm matching transformer.
Combination VHF/UHF antenna (separate VHF
and UHF 300 ohm twin-lead wires)
Connecting a combination VHF/UHL antenna with separate wires:
1 Connect the UHF 300 ohm twin-lead wire to the combiner (not
supplied).
2 Connect the VHF 300 ohm twin-lead wire to the 300-75 ohm
matching transformer.
3 Attach the transformer to the combiner, then attach the combiner
to the RF IN jack.
Separate VHF/UHF antennas (75 ohm VHF cable
and 300 ohm UHF twin-lead wires)
Connecting separate VHF/UHL antennas:
1 Connect the VHF 75 ohm cable and UHF 300 ohm twin-lead wire
to the combiner.
2 Attach the combiner to the RF IN jack.
Connecting to cable television
This television has an extended tuning range and can tune most cable
channels without using a cable television converter box. Some cable
television companies offer
premium pay channels in which the signal is
scrambled. Descrambling these signals for normal viewing requires the
use of a descrambler device which is generally provided by the cable
television company.
For subscribers to basic cable television service
For basic cable service not requiring a converter/descrambler box,
connect the 75 ohm coaxial cable directly to the RF IN jack on the back of
the television.
For subscribers to scrambled cable television
service
Connecting the TV to cable television:
1 If you subscribe to a cable television service which requires the use
of a converter/descrambler box, connect the incoming 75 ohm
coaxial cable to the converter/descrambler box.
2 Using another 75 ohm coaxial cable, connect the output jack of
the converter/descrambler box to the RF IN jack on the television.
Follow the connections shown above.
3 Set the television to the output channel of the converter/
descrambler box (usually channel 3 or 4) and use the converter/
descrambler box to select channels.
