MECHANISM ADJUSTMENT
2.1 Before starting repair and adjustment
2.1.1
Precautions
(1) Unplug the power cord plug of the VCR before using your
soldering iron.
(2) Take care not to cause any damage to the conductor
wires when plugging and unplugging the connectors.
(3) Do not randomly handle the parts without identifying
where the trouble is.
(4) Exercise enough care not to damage the lugs, etc. dur-
ing the repair work.
(5) When reattaching the front panel assembly, make sure
that the door opener of the cassette holder assembly is
lowered in position prior to the reinstallation. (See SEC-
TION 1 DISASSEMBLY.)
(6) When using the Jig RCU, it is required to set the VCR to
the Jig RCU mode (the mode in which codes from the
Jig RCU can be received). (See SECTION 1 DISASSEM-
BLY.)
2.1.2
Checking for proper mechanical operations
Enter the mechanism service mode when you want to oper-
ate the mechanism when no cassette is loaded. (See SEC-
TION 1 DISASSEMBLY.)
2.1.3
Manually removing the cassette tape
1. In case of electrical failures
If you cannot remove the cassette tape which is loaded be-
cause of any electrical failure, manually remove it by taking
the following steps.
(1) Unplug the power cord plug from the power outlet.
(2) Refer to the disassembly procedure and perform the dis-
assembly of the major parts before removing the drum
assembly.
(3) Unload the pole base assembly by manually turning the
loading motor of the mechanism assembly toward the
front. In doing so, hold the tape by the hand to keep the
slack away from any grease. (See Fig.2-1-3a.)
(4) Bring the pole base assembly to a pause when it reaches
the position where it is hidden behind the cassette tape.
(5) Move the top guide toward the drum while holding down
the lug (A) of the bracket retaining the top guide. Like-
wise hold part (B) down and remove the top guide.
Section (C) of the top guide is then brought under the
cassette lid. Then remove the top guide by pressing the
whole cassette tape down. (See Fig.2-1-3b.)
(6) Remove the cassette tape by holding both the slackened
tape and the cassette lid.
(7) Take up the slack of the tape into the cassette. This com-
pletes removal of the cassette tape.
Note:
• For the disassembly procedure of the major parts and
details of the precautions to be taken, see “SECTION
1 DISASSEMBLY”.
