TANDBERG TCD 310 Service Manual

3.6 PAUSE CONTROL
When the PAUSE button is depressed, the gap
between pinch rollers and capstans can be adjusted
with a screw marked *PAUSE ADJUST”, which
can be reached by removing the right side wall.
Insert a cassette and set the deck to PLAY.
Depress the PAUSE button a few times, and check
the following:
— The PAUSE lever should move freely, without
touching the motor support plate or the bracket
of the PAUSE switch. (If required, this bracket
can be bent a little with a screwdriver.)
— When the PAUSE button is depressed, the tape
should stop, and the pinch rollers should be
lifted away from the capstans. The gap must be
wide enough that neither of the pinch rollers
touch the capstans under any circumstance. If
required, adjust with the PAUSE ADJUST screw.
— At the same time, the gap must be so narrow that
the pinch roller solenoid will pull the pinch
rollers in again when the PAUSE button is re-
leased, both during PLAY and RECORD.
IMPORTANT! With the deck in PLAY, release the
PAUSE button and check that the PAUSE lever
can be moved a little up and down (as indicated
with an arrow in the figure). If the lever cannot
be moved, the reason is probably that the PAUSE
ADJUST screw butts against the lever, and the
force of the pinch roller solenoid is transferred to
the lever. The pressure of the pinch rollers is then
correspondingly reduced.
3.7 ADJUSTING THE POSITION OF A
REEL MOTOR
Insert a high quality cassette and close the cassette
compartment. Check that the tape spindle on the
motor is exactly in the center of the correspond-
ing hub on the cassette.
Try the recorder in play, wind and rewind. Check
that the hub runs easily and does not wobble.
If necessary, adjust by loosening the two screws
holding the reel motor. This will be easier if you
remove the circlip on the left side of the cassette
compartment and swing the cassette compartment
upwards (see page 8, step 4).
The ree] motor can now be moved slightly.
3.8. SALVAGING TANGLED TAPE
Occasionally the tape will wind itself around the
last of the two capstans.
To salvage the tape proceed as follows:
1. Remove the bottom plate of the deck.
2. Turn the flywheel of the entangled capstan
slowly against its normal rotation. Use your
finger to turn the flywheel.
3. When the tape has been untangled from the
capstan, wind it manually onto the hubs of
the cassette. Turning the flywheel in order to salvage tangled tape
