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:

Maintenance and inspection
2.5.1 Cleaning
Regular cleaning of the transport system parts is desirable but
practically impossible. So make it a rule to carry out cleaning of
the tape transport system whenever the machine is serviced.
When the video head, tape guide and/or brush get soiled, the
playback picture may appear inferior or at worst disappear, re-
sulting in possible tape damage.
Note:
•
Absolutely avoid sweeping the upper drum vertically as
this will cause damage to the video head.
(1) When cleaning the upper drum (especially the video head),
soak a piece of closely woven cloth with alcohol and while
holding the cloth onto the upper drum by the fingers, turn
the upper drum counterclockwise.
(2) To clean the parts of the tape transport system other than
the upper drum, use a piece of closely woven cloth or a cot-
ton swab soaked with alcohol.
(3) After cleaning, make sure that the cleaned parts are com-
pletely dry before using the cassette tape.
