(1) Observe the CB OUT waveform at the measuring point (D).
(2) Set the VCR to the EVR mode by transmitting the code (F1)
from the Jig RCU.
(3) Set the EVR address to (F2) by transmitting the code (F3)
from the Jig RCU.
(4) Transmit the code (F4) from the Jig RCU to adjust so that
the CB level of the CB OUT waveform becomes the speci-
fied value (G).
(5) Release the EVR mode of the VCR by transmitting the
code (F5) from the Jig RCU again. (When the EVR mode
is released, the adjusted data is memorized.)

(1) Connect the frequency counter to the measuring point
(D1).
(2) Connect the short wire between the short point (D2) and
Vcc (5V).
(3) Short the leads of capacitor (D3) once in order to reset
the microprocessor of the Syscon.
(4) Disconnect the short wire between the short point (D2)
and Vcc then connect it again.
(5) Adjust the Adjustment part (F) so that the output frequency
becomes the specified value (G).
