Antenna Connections

Antennas

•The antenna requirements for good color television reception are more important than those for black & white television reception. For this reason, a good quality outdoor antenna is strongly recommended.

The following is a brief explanation of the type of connections that are provided with the various antenna systems:

1.A 75 ohm system is generally a round cable with F-type connector that can easily be attached to a terminal without tools (not supplied). The F-type connector should be finger tightened only.

2.A 300 ohm system is a flat “twin-lead” cable that can be attached to a 75 ohm terminal through a 300-75 ohm ADAPTOR (not supplied).

CABLE TV (CATV) CONNECTION

•A 75 ohm coaxial cable connector is built into the set for easy hookup. When connecting the 75 ohm coaxial cable to the set, screw the 75 ohm cable to the COAXIAL CABLE CONNECTOR.

•Some cable TV companies offer “premium pay channels”. Since the signals of these premium pay channels are scrambled, a cable TV converter/descrambler is generally provided to the subscriber by the cable TV company. This converter/descrambler is necessary for normal viewing of the scrambled channels. (Set your TV on channel 3 or 4. Typically one of these channels is used. If this is unknown, consult your cable TV company.) For more specific instructions on installing cable TV, consult your cable TV company. One possible method of utilizing the converter/descrambler provided by your cable TV company is explained below.

Please note: RF switch equipped with position A/B (not provided) is required.

“A” position on the RF switch (not supplied) : You can view all unscrambled channels using the TV’s channel keys.

“B” position on the RF switch (not supplied) : You can view the scrambled channels via the converter/ descrambler using the converter’s channel keys.
