If reading/writing data on page 18, set data: 01 to page:
0, address: 10, and then select page 8. By this data set-
ting, the page 18 can be selected.
After the data reading/writing finished, return the data
on page: 0, address: 10 to “00”.

After the completion of the all adjustments, cancel the

RESET button and unplug the main power supply.
(In this case, date and time and menu setting have
been set by users are canceled. Perform resetting)

2) After data on page: D and 18 is restored, select page:

• Before setting the data , select page: 0, address: 01, and set data:

01.

• For page D and 18, the data set will be recorded in the non-

volatile memory by pressing the PAUSE button of the adjust-
ment remote commander. In this case, take note that the test
mode will not be exited even when the main power is turned off
(8.4 Vdc).

• After completing adjustments/repairs, be sure to return the data

of this address to 00, and press the PAUSE button of the adjust-
ment remote commander. And select page: 0, address: 01, and
set data: 00.

When no error occurs in this unit, data “00” is written in the above
addresses (F4 to FF). when first error occurs in the unit, the data
corresponding to the error is written in the first emergency ad-
dress (F4 to F7). In the same way, when the second error occurs,
the data corresponding to the error is written in the second emer-
gency address (F8 to FB).
Finally, when the last error occurs, the data corresponding to the
error is written in the last emergency address (FC to FF).

After completing adjustments, be sure to initialize the data
of addresses F4 to FF to “00”.

Bit values must be discriminated using the display data of the ad-
justment remote commander for the following items.  Us the table
below to discriminate if the bit value is “1” or “0”.

(Example) If the remote commander display is “8E”, bit value from

bit 7 to bit 4 can be discriminated from the column 

A

,

and those from bit 3 to bit 0 from column 

B

.

Address 0E

Using method:
1) Select page: 7, address: 0E.
2) By discriminating the bit value of display data, the state of the

switches can be discriminated.

Address 0C

Using method:
1) Select page: 7, address: 0C.
2) By discriminating the bit value of display data, the state of the

switch can be discriminated.
