Tape Head and Capstan Cleaning

  2. Clean the head and the capstan every 50 hours of operation.

Clean Tape Indicator Feature

The cassette and remote cassette units will remind the user to clean the cassette head.

The clean tape indicator will be cancelled and the timer reset when the eject button is pressed and held for approximately 5 seconds.

When the feature has been cancelled, CLN appears on the screen.
