Mechanism service mode

This model has a unique function to enter the mechanism into ev-
ery operation mode without loading of any cassette tape. This
function is called the “Mechanism service mode”.

2.6.1

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) Release the lug of the Cassette holder and then slide the

Cassette holder toward the direction where the Cassette
holder is loaded by manually.

(4) The cassette holder lowers and, when the loading has

completed, the mechanism enters the desired mode.
When the VCR is set to the Mechanism service mode, the
symbols (“Timer”) in the FDP (LED) are blinked.

Maintenance and inspection

2.7.1

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.

2.7.2

Lubrication

With no need for periodical lubrication, you have only to lubricate
new parts after replacement. If any oil or grease on contact parts
is soiled, wipe it off and newly lubricate the parts.

Note:

•

See the “mechanism assembly” diagram of the “parts
list” for the lubricating or greasing spots, and for the
types of oil or grease to be used.

2.7.3

Suggested servicing schedule for main components

The following table indicates the suggested period for such ser-
vice measures as cleaning, lubrication and replacement. In prac-
tice, the indicated periods will vary widely according to
environmental and usage conditions. However, the indicated
components should be inspected when a set is brought for ser-
vice and the maintenance work performed if necessary. Also
note that rubber parts may deform in time, even if the set is not
used.
