ADJUSTMENT REMOTE COMMANDER
(RM-95)
The adjustment remote commander (RM-95) is used for changing
the calculation coefficient in signal processing, EVR data, etc. The
adjustment remote commander (RM-95) 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.
1.
Using the Adjustment Remote Commander (RM-95)
1) Connect the adjustment remote commander to the LANC ter-
minal.
2) Set the HOLD switch of the adjustment remote commander
(RM-95) to “HOLD” (SERVICE position). If it has been prop-
erly connected, the LCD on the adjustment remote commander
(RM-95) will display as shown in Fig. 6-4-1.
