: 5-wire flat cable for VP-1
PWB assembly
RELAY JIG
Connect
the flat cable end from the cylinder
assembly
to the
VP-1
PWB
assembly
using the relay jig to provide
simple
repairing
of the VP-1
PWB assembly,
as shown
in Fig.2-2-3.
Further,
when adjusting
the VP-1
PWB assembly,
be sure to
make contact
an end of shield case with bracket
of the VP-1
PWB assembly
to maintain
the shield effect.
If the VP-1
PWB
assembly
does not contact, there is insufficient
ground and no
proper play back image can be obtained.
