Before using your TV/monitor as a monitor, be sure you have made all
necessary connections.

1.  Plug the TV/monitor's power cord into an AC outlet.

    NOTE:  The power cord has a polarized plug, one of the plug's blades is
           wider than the other. If you do not have a polarized outlet,
           have one installed before using the TV/monitor.

2.  Turn on the TV/monitor by pressing (POWER) on the front panel or remote
    control.

3.  Press (TV/VCR) until VIDEO displays on screen.

4.  Activate the signal source you connected to the TV/monitor's AUDIO/
    VIDEO IN jacks (VCR, video disk player, external TV tuner, satellite
    receiver, and so forth).

5.  Adjust the CONTRAST, BRIGHTNESS, and COLOR for the best picture.

6.  Use the (VOLUME) up and down arrow buttons and the (BALANCE) control to
    get the desired sound.

NOTES:  (MUTE) does not affect the TV/monitor's AUDIO OUTPUT signal.

        The TV/CATV switch, cable type, and (CHANNEL) buttons have no
        effect when the TV/monitor is in the VCR (video) mode.

Using the VIDEO/AUDIO OUTPUT Jacks

You can connect a VCR to he TV/monitor's VIDEO and AUDIO OUT jacks to
record a channel you select with the TV/monitor's tuner. The TV/monitor's
tuner always controls the channel that is sent to its VIDEO/AUDIO OUT
jacks, even when the  TV/monitor is in the VCR (VIDEO) mode.

Picture Adjustments

The TV/monitor is a highly sophisticated instrument. It has been carefully
checked and adjusted at the factory under the most rigid quality control
and inspection systems. However, if any adjustments are necessary, adjust
the front panel controls as follows:

1.  Press (PICTURE SELECT). The picture adjustment options appear on the
    screen in the following sequence; CONTRAST, BRIGHTNESS, COLOR, AND
    TINT.

2.  For each picture adjustment option, press PICTURE SELECT (UP) or (DOWN)
    until you see the best picture.

The effects are shown below:

                            Down                               UP
TINT                        to green                           to purple
COLOR                       to pale                            to brilliant
BRIGHTNESS                  to decrease brightness             to increase
CONTRAST                    to decrease contrast               to increase

More About Your TV/MONITOR

If you are not familiar with MTS broadcasts or do not know  how a
TV/monitor is different from a regular TV, the following information can
be helpful.

Multi-Channel Television Sound

Beginning in 1984, the FCC allowed television stations to broadcast multi
channel stereo audio signals. Now, major networks are using MTS for some of
their programming. However, not all local stations are equipped to pass
along the MTS signals. In addition to the stereo sound track, an MTS
broadcast might include a separate mono signal audio program (SAP). The
SAP signal can be used for a second language or additional commentary for
the video program.

The stereo and SAP signals are specially encoded and similar in quality to
FM stereo broadcasts, but they cannot be received or decoded by an FM
radio tuner. The signals require a special multi-channel sound tuner, such
as the one in your TV/monitor.

NOTE:  If a TV or VCR does not have a multi-channel sound tuner, the
       signals will be received in mono, as usual.  After you connect the
       TV/monitor to an antenna, indicators tell you a station is
       broadcasting an MTS signal, and if a SAP signal is present.  Then
       you can select which signal to listen to.

NOTE:  MTS signals are used primarily by broadcast TV channels. If you are
       receiving local TV stations as a part of a standard 36-channel cable
       service, multi-channel sound signals might not be included. Some
       premium cable channels offer stereo sound, but these signals, often
       sent through the cable wire, are designed to be received by a
       standard FM stereo tuner. In such cases, use your stereo system
       tuner or receiver to provide sound while you watch the TV/monitor.

What is a TV/MONITOR?

VHF, UHF, and cable TV signals necessary for a regular TV are combined
audio and video (sound and picture). They usually come from an antenna or
cable system connected to the VHF or UHF terminals on a TV set. A video
monitor uses separate audio and video signals. These separate signals
(called base-band signals) might come from a VCR, a Video disk player, and
external TV tuner, a satellite receiver, a video camera, or a computer.
Your Radio Shack TV/monitor can receive either signal.

Separate audio and video signals allow more flexibility in your audio/video
system. You can connect the TV/monitor to audio/video processors, or
directly to your stereo amplifier/receiver. The separate A/V signals
usually provide a better picture and sound than the combination audio/video
signals (UHF, VHF, or cable).
