2.4 Service position 

This unit has been designed so that the Mechanism and Main
board assemblies can be removed together from the chassis as-
sembly. Before diagnosing or servicing the circuit boards, take
out the major parts from the chassis assembly.

2.4.1 How to set the “Service position”

(1) Refer to the disassembly procedure and perform the disas-

sembly of the major parts before removing the Mechanism
assembly.

(2) Remove the screws that fix the Mechanism assembly to

the Chassis assembly. If any other screws are used to fix
the boards, remove them also.

(3) Remove the combined Mechanism and Main board assem-

blies.

(4) If any other major parts are used, remove them also.
(5) Connect the wires and connectors of the major parts that

have been removed in steps (1) to (4). (Refer to Fig. 2-4-
1a.)

(6) Place the combined Mechanism, Main board and other

board assemblies upside down.

(7) Insert the power cord plug into the power outlet and then

proceed with the diagnostics and servicing of the board as-
sembly.

Notes:

Before inserting the power cord plug into the power out-
let, make sure that none of the electrical parts are able
to short-circuit between the workbench and the board
assembly.

For the disassembly procedure of the major parts and
details of the precautions to be taken, see “2.2 Remov-
ing the major parts”.

If there are wire connections from the Main board and
Mechanism assemblies to the other major parts, be sure
to remove them (including wires connected to the major
parts) first before performing step (2).

When carrying out diagnosis and repair of the Main
board assembly in the “Service position”, be sure to
ground both the Main board and Mechanism assem-
blies. If they are improperly grounded, there may be
noise on the playback picture or FDP counter display
may move even when the mechanism is kept in an inop-
erative status.

In order to diagnose the playback or recording of the
cassette tape, set the Mechanism assembly to the re-
quired mode before  placing it upside down. If the mech-
anism mode is changed (including ejection) while it is in
an upside down position the tape inside may be dam-
aged.

For some models, the mechanism and board assem-
blies are attached by connectors only. When carrying
out a diagnosis or repair of the boards in the “Service
position”, make sure that the connectors are not dis-
connected.

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 sets the VCR to the Jig RCU
mode as initial setting.

Fig.2-5a  User/Jig RCU mode

2.5.1 Setting the Jig RCU mode

(1) Turn on the power.
(2) Press the following remocon keys continuously within 2

seconds " MENU " 

 " 2 " 

 " 8 " 

 " OK ".

Note:

When the VCR is set to the Jig RCU mode, the symbols
( " : " ) in the time display of the FDP are turned off.
(7 segment LED display model)

When the VCR is set to the Jig RCU mode,the "POWER"
button of RCU will not work.
