VIDEO NAVIGATION
CORRECTIVE ACTION
Tape information cannot be shown if it
has not been recorded on this VCR.
Video Navigation cannot work
correctly on a tape if it has more than
one tape number. If this happens, fast-
forward the tape up to its end, eject it,
and try it again.
Check the remaining memory
(
੬
␣ pg.␣ 51). If it is full, delete
unnecessary Video Navigation
information. (
੬
pg. 50, 51).
SYMPTOM
1. Tape infomation screen does not
appear for the currently inserted
tape.
2. The VCR cannot search for the
correct program.
3. “MEMORY FULL” appears on the
screen when you try to start
recording.
POSSIBLE CAUSE
● The current tape inserted has not
been recorded on this VCR.
● Two (or more) tape numbers are
recorded on one tape.
● The VCR’s memory for Video
Navigation is fully recorded.
ATTENTION
This VCR contains microcomputers. External electronic noise or interference can cause microcomputer to malfunction. If the
VCR does not operate correctly switch its power off and unplug the AC power cord from the AC supply. Wait for a while and
then plug the power back in. Eject and check the condition of the cassette. If everything appears normal, you can operate the
VCR as usual.
MOISTURE CONDENSATION
Moisture in the air will condense on the VCR when you move it from a cold place to a warm place, or under
extremely humid conditions—just as water droplets form on the surface of a glass filled with cold liquid. Moisture
condensation on the head drum will cause damage to the tape. In conditions where condensation may occur, keep the
VCR turned on for a few hours to evaporate the moisture before inserting a tape.
ABOUT HEAD CLEANING
Accumulation of dirt and other particles on the video heads may cause the playback picture to become blurred or
interrupted. Be sure to contact your nearest JVC dealer if such troubles occur.
