1. Kit and dummy load
The existing jig kit and dummy load are available only if these are kept in stock.
In the future, no jig kits and dummy loads will be put into inventory any more.
Reasons;
If any part of these items is not obtainable, no complete kit can be established any more.
Therefore, the maintenance of the inventory is impossible to continue.
The dummy load is expensive. In addition, it is extremely difficult to establish the former
model of a dummy load again.
If our supply system is maintained so that a single jig kit can be supplied, we can easily
accept an ordering for the supply of parts.
2. Method of optical axis alignments without a dummy load
In regard to the VT70, VT80, VT90, NP3150, NP3250, VT700, and NP905 Series, we have
made optical axis alignments by means of a dummy load. In the future, please make optical
axis alignments with the use of the extension connector and the extension connector PWB in
the same manner as for the polarizer alignments.
(The method of connection to make optical axis alignments with the use of the extension
connector and the extension connector PWB is the same as for the polarizer alignment. This
method is used for the NP600, NP610, and NP-M Series.)
In regard to the extension connector and the extension connector PWB needed to make
connections with the MAIN PWB, please refer to the relevant Service Manual (method of
adjustment, list of jigs) for each model.
