DECK MECHANISM ADJUSTMENT
2. Previous Preparation for Deck Adjustment
(Preparation to load the VCR (VCP) with cassette tape not inserted)
3. Torque Measuring
1) Unplug the power cord.
2) Separate the top cover and the plate assembly top.
3) Plug in power cord.
4) Turn the VCR (VCP) on and load the cassette while
pushing the lever stopper of the holder assembly CST
backward. In this case, clog both holes on the housing rail
part of chassis to prevent detection of the end sensor.
If doing so, proceeding to the stop mode is done. In this
status, input signals of all modes can be received.
However, operation of the Rewind and the Review is
impossible since the take-up reel remains at stop status
and so cannot detect the reel pulse (however, possible for
several seconds).
Purpose of Measuring: To measure and check the reel torque on the take-up part and the
supply part that performs basic operation of the VCR (VCP) for
smoothly forwarding the tape.
Measure and check followings when the tape is not smoothly
wound or the tape velocity is abnormally proceeded:

Measuring method
• Torque Gauge
• Play (FF) or Review
• Try to operate the VCR (VCP) per mode with the
