4-1. ADJUSTING REMOTE COMMANDER

The adjusting remote commander is used for changing the calculation
coefficient in signal processing, EVR data, etc. The adjusting
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. Using the adjusting remote commander

1) Connect the adjusting remote commander to the LANC terminal.
2) Adjust the HOLD switch of the adjusting remote commander to
"HOLD" (SERVICE position).
If it has been properly connected, the LCD on the adjusting
remote commander will display as shown in Fig. 5-4-1.
