Adjusting method:
1) Adjust the output voltage of the regulated power supply so
that the digital volt meter display is 7.2 ± 0.1 Vdc.
2) Turn off the power supply.
3) Turn the HOLD switch of the adjusting remote commander.
4) Turn on the power supply.
5) Insert the memory stick to the unit, and set the STILL mode.

8) Decrease the output voltage of the regulated power supply so
that the digital voltmeter display is 5.50 ± 0.01 Vdc.
9) Select page: 2, address: 51, read the data, and this data is named
Dref.
10) Select page: D, address: 90, set data Dref, and then press the
PAUSE button of adjusting remote commander.
11) Convert Dref to decimal notation, and obtain Dref’.
(Refer to Table 5-2-2. “Hexadecimal-decimal conversion
table”)
12) Calculate D91’, D92’, D93’ and D94’ using following equations
(decimal calculation), convert it to a hexadecimal number, and
input each adjustment address.
Address: 91 D91’ = Dref’+8
Address: 92 D92’ = Dref’+23
Address: 93 D93’ = Dref’+44
Address: 94 D94’ = Dref’+55
Note: After setting each data, be sure to press the PAUSE but-
ton.
Processing after Completing Adjustments:
