ADJUSTMENT REMOTE COMMANDER
(RM-95)
(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.
