4.3.3 Previous Preparation for Deck Adjustment
(Preparation to load the VCR (VCP) with cassette tape not inserted)
(1) Take the power cord from the consent.
(2) Separate the top cover and the plate assembly top.
(3) Insert the power cord into again.
(4) Turn the VCR (VCP) on and load the cassette while push-
ing the lever stopper of the holder assembly CST back-
ward. 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).
4.3.4 Torque Measuring
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:
Adhere the torque gauge adaptor to the torque gauge for measuring the value.
