ADJUSTMENT REMOTE COMMANDER
The adjustment remote commander is used for changing the cal-
culation coefficient in signal processing, EVR data, etc. The ad-
justment remote commander performs bi-directional
communication with the unit using the remote commander signal
line (LANC). The resultant data of this bi-directional communica-
tion is written in the non-volatile memory.

Using the Adjustment Remote Commander
1) Connect the adjustment remote commander to the LANC ter-
minal.
2) Set the HOLD switch of the adjustment remote commander to
“HOLD” (SERVICE position). If it has been properly con-
nected, the LCD on the adjustment remote commander will
display as shown in Fig. 6-4-1.

Mishandling of the adjustment remote commander may erase the
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.
