Troubleshooting

VTR fails to operate as per the
mode selected on the menu
screen.
VTR fails to operate even when a
function button is pressed.
Recording and/or editing cannot
be performed.
How to eject the tape in an emergency
1. Remove four screws from both sides of the front panel and then remove the VTR's top panel.
2. The mechanism is moved in the unloading direction by turning the loading motor clockwise.
Since tape slack now develops, proceed with the following 4 steps to take up the tape.
3. Insert a screwdriver into hole A (for an S or M cassette) or hole A' (for an L cassette), and
press the manual lever of the take-up reel. The tape will be taken up by pressing this lever.
4. Remove the tape from the cylinder by performing the operations in steps 2 and 3. (When
turning the loading motor, keep turning it until the position is reached where it will turn no fur-
ther. Bear in mind that turning the motor past this position will cause the gear engagement
to fail and/or other problems.)
5. To release the sub-loading, insert a screwdriver or other tool into hole B, and while turning it
clockwise, take up the tape by performing the operation in step 3. (Bear in mind that contin-
uing to turn the screwdriver even after the sub-loading status has been released will cause
the gear engagement to fail and/or other problems.)
6. Check that all the tape has been taken up, and that its unloading has been completed. In
order to eject the cassette, insert a screwdriver or other similar tool into hole C, and turn it
counterclockwise. (Bear in mind that continuing to turn the screwdriver even after the cas-
sette has been ejected will cause the gear engagement to fail and/or other problems.)
