Maintenance

PHILIPS recommends two periodic maintenance steps to insure the peak performance of the LTC 3924/62.

1.Periodically make a careful observation of the quality of the playback video. If there are exces- sive dropouts (noise specks) across the video pic- ture, and the TRACKING control does not clear the picture, then head cleaning may be necessary. Obtain a high quality head cleaning kit, and follow the directions carefully. The length of time between cleaning depends on the amount of air- borne contaminates around the tape recorder and/or cassette.

2.Have the LTC 3924/62 inspected every 3500 hours of continuous usage by the dealer from whom the recorder was purchased.
