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.
Fig. 6-4-1
3) Operate the adjustment remote commander (RM-95) as fol-
lows.
• Changing the page
The page increases when the EDIT SEARCH+ button is
pressed, and decreases when the EDIT SEARCH- button is
pressed. There are altogether 16 pages, from 0 to F.
• Changing the address
The address increases when the FF (M) button is pressed,
and decreases when the REW (m) button is pressed. There
are altogether 256 addresses, from 00 to FF.
• Changing the data (Data setting)
The data increases when the PLAY (N) button is pressed,
and decreases when the STOP (x) button is pressed. There
are altogether 256 data, from 00 to FF.
• Writing the adjustment data
The PAUSE button must be pressed to write the adjustment
data in the nonvolatile memory. (The new adjusting data will
not be recorded in the nonvolatile memory if this step is not
performed)
4) After completing all adjustments, turn off the main power sup-
ply (8.4 V) once.

Precautions Upon Using the Adjustment Remote
Commander (RM-95)
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.
