1.9 Jig RCU mode
This unit uses the following two modes for receiving remote
control codes.
1) User RCU mode : Ordinary mode for use by the user.
2) Jig RCU mode
: Mode for use in production and serv-
icing.
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
EEPROM, 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
necessary operations have been completed. These modes can be
set by the operations described below.
1.9.1 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 plug
into the power outlet.
When the VCR is set to the Jig RCU mode, the symbols
( “ : ” ) in the time display of the FDP are turned off.
1.9.2 Setting the User RCU mode
(1) Turn off the power.
(2) Press the “REC” and “PAUSE” buttons of the VCR simul-
taneously. Alternatively, transmit the code “80” from the
Jig RCU.
