� Adjustment 1. If the take-up torque is outside the range, clean the capstan D.D. motor pulley, drive belt and limiter pulley with cleaning liquid, then recheck the torque. 2. If the take-up torque is still out of range, replace the drive belt. Notes: 1. Hold down the torque gauge so that it may not fly off. 2. When checking the take-up torque, do not keep the reel disk locked for a longer time.
CHECKING AND ADJUSTMENT OF TAKE-UP TORQUE IN VIDEO SEARCH REWIND MODE
� Remove the cassette housing control assembly. � Make a short-circuit between TP701 and TP702, both located at the center on your side on the main PWB. Now turn on the power. � Setting 1. Push the PLAY button to place the ass�y in the playback mode. 2. Push the REW button to place the ass�y in the video search rewind mode. � Checking 1. Place the torque gauge on the supply reel disk, and turn it counterclockwise(CCW) very slowly (one rotation every 1 to 2 seconds) and check that the torque is within the set value 13.7 ± 4.3mN�m (140 ± 45gf�cm).
CHECKING AND ADJUSTMENT OF TAKE-UP TORQUE IN PLAYBACK MODE
1. Remove the cassette housing control assembly. 2. Make a short-circuit between TP701 and TP702, both located at the center on your side on the main PWB. Now turn on the power. 3. Open the lid of the cassette torque meter, and hold it with two pieces of vinyl tapes. 4. Load the cassette torque meter into the unit. 5. Put the weight (500g) on the cassette torque meter. 6. Press the REC button to put the unit in REC mode. Set value SP10.5 ± 3.8mN�m (107 ± 39gf�cm)

� Checking 1. Check that the torque is in the range of 10.5 ± 3.8mN�m (107 ± 39gf�cm). 2. The torque fluctuates due to the rotational deviation of the limiter pulley ass�y. Use the center of the fluctuation as the value. 3. Place the ass�y in the SP record mode, and check that the take-up torque is within the range. � Adjustment If the take-up torque in the playback mode is outside the range, replace the limiter pulley ass�y. Note: Stabilize the cassette torque meter to prevent floating. 13
Note: Set the torque gauge securely on the supply reel disk. If it is not secure, the measurement will be incorrect. � Adjustment If the take-up torque in video search rewind mode is outside the range, replace the limiter pulley ass�y. Note: The torque fluctuates due to the rotational deviation of the limiter pulley ass�y. Use the center of the fluctuation at the value.
