ADJUSTING REMOTE COMMANDER

The adjusting remote commander is used for changing the calcu-
lation coefficient in signal processing, EVR data, etc. The adjust-
ing remote commander performs bi-directional communication
with the unit using the remote commander signal line (LANC).
The resultant data of this bi-directional communication is written
in the non-volatile memory.

1. Used the Adjusting Remote Commander

1) Connect the adjusting remote commander to the CN706 on
the SY-77 Board via CPC-9 jig (J-6082-393-C).
2) Set the HOLD switch of the adjusting remote commander to
"HOLD" (SERVICE position).
3) Turn on the power with the POWER switch of the unit.

correct adjustment data at times. To prevent this, it is recommended
that all adjustment data be noted down before beginning adjust-
ments and new adjustment data after each adjustment.
