The characters shown in the parenthesis (  ) shown the display on the adjustment remote commander.

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.

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.

If reading/writing data on page 18, 1C, set data: 01 to
page: 0, address: 10, and then select page 8, C. By this
data setting, the page 18, 1C 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
service mode by either of the following ways.
1) After data on page: A, 18, 1C is restored, press 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: A, 18, 1C is restored, select page:

0, address: 01, and return the data to 00. And when
data on page: 7 is changed, return data to the original
condition.

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

01.

• For page A, 18, 1C 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”.
