2.5 Mechanism service mode
This model has a unique function to enter the mechanisminto ev-
ery operation mode without loading of any cassette tape. This
function is called the "Mechanism service mode".
2.5.1 How to set the "Mechanism service mode"
(1) Set the VCR to the Jig RCU mode (the mode in which
codes from the Jig RCU can be received).
(2) Transmit the code "E5" from the Jig RCU.
(3) With lock levers (A) (B) on the left and right of the Cassette
holder assembly pulled toward the front, slide the holder in
the same direction as the cassette insertion direction. (For
the positions of lock levers (A) (B), refer to the "Procedures
for Lowering the Cassette holder assembly" of 2.3 Disas-
sembly/assembly method.)
(4) The cassette holder lowers and, when the loading has
completed, the mechanism enters the desired mode.
2.6 Jig RCU mode
This unit uses the following two modes for receiving remote con-
trol codes.
1) User RCU mode : Ordinary mode for use by the user.
2) Jig RCU mode
: Mode for use in production and servicing.
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). As both of the above two modes are stored in the EE-
PROM, it is required to set the VCR back to the User RCU mode
each time that an adjustment is made or to check that the neces-
sary operations have been completed. These modes can be set
by the operations described below.
Note:
• Confirm the RCU mode when exchanged parts. Since
some SERVICE PARTS set the VCR to the Jig RCU mode
as initial setting.
2.6.1 Setting the Jig RCU mode
(1) Unplug the power cord plug from the power outlet.
(2) Press and hold the "REC" and "PAUSE" buttons on the
VCR simultaneously, while plugging the power cord plugin-
to the power outlet. When the VCR is set to the Jig RCU
mode, the symbols ( " : " ) in the time display of the FDP are
blinking.
2.6.2 Setting the User RCU mode
(1) Turn off the power.
(2) Press the "REC" and "PAUSE" buttons of the VCR simulta-
neously. Alternatively, transmit the code "80" from the Jig
RCU.
