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.
1.
Using the Adjustment Remote Commander
1) Connect the adjustment remote commander to CN1011 of VC-
305 board via I/F unit for LANC control (J-6082-521-A) and
CPC jig connector (J-6082-539-A).
The “Jig Modification” is necessary for connecting the adjust-
ment remote commander to this set.
Modify the jig by referring to page 6-5.
To operate the adjustment remote commander, connect the AC
power adapter (8.4 Vdc) to the DC IN jack of I/F unit for LANC
control, or connect the L series Info-LITHIUM battery to the
battery terminal of I/F unit for LANC control.
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.
Fig. 6-4-1
3) Operate the adjustment remote commander as follows.
• 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.

2. Precautions Upon Using
the Adjustment Remote Commander
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.

Note:
The characters shown in the parenthesis (  ) shown the display on the adjustment remote commander.
(Example)
If the DDS display or the adjustment remote commander shows BD (
bd
);
Because the upper digit of the adjustment number is B (
b
), and the lower digit is D (
d
), the meeting point 
“189” of 1 and 2 in the above table is the corresponding decimal number.

DATA PROCESS
The calculation of the DDS display and the adjustment remote
commander display data (hexadecimal notation) are required for
obtaining the adjustment data of some adjustment items. In this
case, after converting the hexadecimal notation to decimal nota-
tion, calculate and convert the result to hexadecimal notation, and
use it as the adjustment data. Indicates the hexadecimal-decimal
conversion table.
