Reference

Can’t select certain channel or turns off while playing

Channel may be blocked or not approved in the Parental Controls menu.

If using a VCR, check to make sure the TV/VCR switch on the VCR is in the correct position.

Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on
again. If this happens frequently, the voltage in your house may be abnormally high or low.

Noisy stereo reception

May be a weak station. Use Audio menu to choose Mono sound.

No picture, no sound but TV is on

Maybe the cable/air function is set to the wrong position.

Maybe a vacant channel is tuned.

If watching a VCR (connected only through antenna input), make sure your TV is tuned to channel 3 or 4—the same
as the CH3/4 switch on your VCR. Also check to make sure the TV/VCR switch on your VCR is in correct position.

Sound okay, picture poor

Check antenna connections.

Try adjusting sharpness function to improve weak signals.

CARE AND CLEANING

CAUTION: Turn OFF your monitor before cleaning.

You can clean the monitor as required, using a soft lint-free cloth. Be sure to occasionally dust the ventilation slots in

the cabinet to help assure adequate ventilation.
The monitor’s screen may be cleaned with a soft, lint-free cloth as well. Take care not to scratch or mar the screen. If

necessary, you may use a cloth dampened with warm water.

Never use strong cleaning agents, such as ammonia-based cleaners, or abrasive powder. These types of cleaners will

damage the monitor.
While cleaning do not spray liquid directly on the screen, or allow liquid to run down the screen and inside the monitor.

Also, avoid placing drinks or vases with water on top of the monitor. This could increase the risk of fire or shock hazard or

damage to the monitor.
Caution: If fixed (non-moving) images are left on the screen for long periods, they may be permanently imprinted on the

screen. Such images include network logos, phone numbers, and video games. This damage is not covered by your
warranty. Extended viewing of channels displaying these images should be avoided.

RADIO INTERFERENCE

This equipment has been type tested and found to comply with the limits for a Class B Digital Device in accordance with

the specifications in Part 15 of FCC Rules. These rules are designed to provide reasonable protection against radio and

television interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with

the instructions, may cause harmful interference to radio communications. However, there is no guarantee that

interference will not occur in a particular installation.

If this equipment does cause interference to radio or television reception (which you can determine by turning the
equipment off and on), try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna (that is, the antenna for radio or television that is “receiving” the

interference).

Change the position of the multimedia monitor with respect to the radio or television equipment that is receiving

interference.

Move the multimedia monitor away from equipment receiving interference.

Plug the multimedia monitor into a different wall outlet so the receiver and equipment receiving interference are on

different branch circuits.

If these measures do not eliminate interference, please consult your dealer or an experienced radio/television technician

for additional suggestions. Also, the Federal Communications Commission has prepared a helpful booklet, “How To

Identify and Resolve Radio/TV Interference Problems”. This booklet is available from the U.S. Government Printing
Office, Washington, D.C. 20402. Please specify stock number 004-000-00345-4 when ordering copies.
