Moisture Condensation
Moisture condensation can occur:
• When the DVD/VCR Receiver is moved from a cold
place to a warm place.
• Under extremely humid conditions.
In locations where moisture condensation may occur:
•
Keep the DVD/VCR Receiver plugged into an AC
power outlet with POWER On. This will help prevent
condensation.
• When condensation has occurred, wait a few hours
for the DVD/VCR Receiver to dry before using it.
Video Head Cleaning
The dirt accumulating on the head after a long period of time can cause the playback picture to become blurred or
broken up. High quality video cassette tapes will not normally deposit dirt onto the video head, but old or damaged
tapes might.
