1). U10 Dew formation Wait until the indication disappears. 2). H01 After cylinder lock is detected, the cylinder does not start rotating again even after tape unloading. Check the cylinder-motor drive circuit. 3). H02 Cassette tape is not wound up during tape unloading except Eject mode. Check the capstan-motor drive circuit. 4). F03 Mechanism locks during mode transition except Eject mode. 1. Check the loading-motor drive circuit. 2. Check the mechanism phase alignment. 3. Check the Mode Switch. 5). F04 Mechanism lock during tape unloading. 1. Check the loading-motor driveї circuit. 2. Check the mechanism phase alignment. 6). F05 Cassette tape is not wound up during tape unloading in Eject mode. 1. Check the capstan-motor drive circuit. 2. Check the Supply/Take-up reel pulse. 7). F06 Mechanism locks after tape unloading in Eject mode. 1. Check the loading-motor drive circuit. 2. Check the mechanism phase alignment for Cassette Holder Unit. 8). F09 No serial clock transmission between IC6001 and IC7501. Check the serial clock circuit.
