(3) Set the VCR to the EVR mode by transmitting the code
(F1) from the Jig RCU.
(4) Set the EVR address to (F2) by pressing the button of
the digit-key remote controller.
(5) Adjust with the channel buttons (+,–) on the VCR (or on
the remote controller) so that the frequency of the meas-
uring point (D1) becomes the specified value (G).
(6) Release the EVR mode of the VCR by transmitting the
code (F1) from the Jig RCU again. (When the EVR mode
is released, the adjusted data is memorized.)
(7) Disconnect the short wire between the short point (D2)
and the GND (Ground).
