1-13. 50-pin Connector
The position of the 50-pin connector on the VTR is
previously calibrated at the factory with a special tool. If
this position is incorrect, the VTR connector cannot make
positive contact with the camera or so. Therefore, do not
remove the fixing screws of the V connector holder and
50-pin connector except in an emergency.
. When you check the 50-pin connector portion, remove
the C holder cap as shown in the figure.
. If the lead wire is happened to be open at the 50-pin
connector portion, solder the lead wire and contact.
