OPERATION TV FUNDAMENTALS

Introducing

you to the
basics of your
Entertainment

Machine.

Basic Television Operation

On some models A/V input is designated as a channel that is one below
the lowest/one above the highest. You’ll have to use the Channel
Up/Down buttons to access it. The Time/Channel display will read “Video”
in place of a channel number.

Cable/Antenna Input: This setting allows you to change cable or
antenna channels and to view videocassettes on channel 3 (or 4) in mono
sound.

Video Input: This setting allows stereo playback of videocassettes. The
television cannot change channels in the Video mode, but the VCR can.

To view the current input source, press ENTER on your remote. The
Time/Channel display should appear in the upper right hand cor­ner of the screen. If the display reads ‘Video,’ then the source is
an A/V input. If the display reads a channel number, then the
source is your Cable or Antenna.

CHANNEL UP/DOWN arrows: Use these arrows to change the channels.
Auto Program will have found all channels available to you.

NUMBER Keypad: To skip to any channel, enter the number of the
channel using the NUMBER key pad, then press ENTER.

FLASHBACK: To instantly return to the last channel viewed,
press FLASHBACK.

Volume Right/Left: To adjust the volume level, use the volume Right/Left
arrows. To silence your TV instantly, press MUTE. To get the sound back,
press MUTE again.
