• External influences such as lightning, static electricity, may cause improper
operation. In this case, operate the unit after first turning on the power of the
Display and the AVC System, or unplugging the AC cord and replugging it in
after 1 or 2 minutes.

• Are batteries inserted with polarity (e, f) aligned? (See page 12.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fluorescent lighting?
• Is a fluorescent light illuminated near the remote control sensor?

53)

Troubleshooting
Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly
delayed. This is not a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near
a heater, as this may cause the cabinet to deform and the Liquid Crystal panel to malfunction.
Storage temperature: –4°F to +140°F (–20°C to +60°C)
