Note: J-6082-053-B
(2) Extension cable (for remote commander plug converter)
J-6082-291-A
Note: The page will not be changed over, unless the microprocessor in
the adjusting remote commander is a new one (uPD7503-G-C56-
12). In such a case, replace with new microprocessor (8-759-148-
35).
2. Adjusting Remote Commander
For the adjustment, the adjustment data saved in the nonvola-
tile memory (EEPROM) must be rewritten, and for this pur-
pose the adjusting remote commander is used.
The adjusting remote commander makes two-way communi-
cation with the set using a remote control signal line (LANC).
The adjusting remote commander transmits pages, addresses,
and data up/down commands to the set. The set transmits pages,
addresses, and data to the adjusting remote commander.
3. How to Use The Adjusting Remote Commander
(1) Connect the adjusting remote commander to the CN305 on
YM-A01 board via extension cable (J-6082-291-A).
( At this time, set the switch of extension cable to OFF
(OPEN) position
Turn ON the power on the set.
(2) Set the HOLD switch on the adjusting remote commander to
the HOLD (SERVICE) position.
If connection is normal, the LCD display on the adjusting
remote commander will be as shown in Fig.3-3.

The PAUSE button must be pressed to write adjustment
data (D page) to the nonvolatile memory (EEPROM). (Un-
less the PAUSE is pressed, new data are not saved in the
nonvolatile memory.)

input to page: D is enabled.
(5) After the adjustment finished, select page: 1, address: 00,
and set 00 data. Thus, the data change on page: D is dis-
abled.
(6) After all adjustments finished, turn OFF the main power sup-
ply (9 V) once.
4. Precaution on Use of The Adjusting Remote Commander
Misoperation of the adjusting remote commander could erase

of data from page: D before adjustment, and also to make a
note of new adjustment data each time the adjustment of one
item is finished.
