72 EN TROUBLESHOOTING (cont.) VIDEO NAVIGATION SYMPTOM 1. Tape infomation screen does not appear for the currently inserted tape. 2. The VCR cannot search for the correct program. POSSIBLE CAUSE ● The current tape inserted has not been recorded on this VCR. ● Two (or more) tape numbers are recorded on one tape. 3. "MEMORY FULL" appears on the screen when you try to start recording. OTHER PROBLEMS SYMPTOM 1. When scanning channels, some of them are skipped over. 2. The channel cannot be changed. ● The VCR's memory for Video Navigation is fully recorded. POSSIBLE CAUSE ● Those channels have been preset to be skipped. ● Recording is in progress. 3. The Remote will not operate your TV or cable box or DBS receiver. 4. Even though Auto or Semiauto Clock Set has been performed, the clock is incorrect. ● The brand codes are set incorrectly. ● The clock setting data received from the host channel is incorrect. 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, fastforward 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). CORRECTIVE ACTION If you need the skipped channels, restore them (੬ pg. 14). Press PAUSE ( 8 ) to pause the recording, change channels, then press PLAY ( 3 ) to resume recording. Reset the correct brand codes (੬␣ pg.␣ 66, 67 or 68). Select a different host channel during Semiauto Clock Set (੬ pg. 11), or perform Manual Clock Set (੬ pg. 12). 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. 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.
