Switch setting:
1) AUTO FOCUS .................................................................OFF
2) LCD display ................................................................. Closed
3) View finder ............................. ON (View finder is pulled out)
Connection:
1) Connect the regulated power supply and the digital voltmeter
to the battery terminal as shown in Fig. 5-3-3.
Adjusting method:
1) Adjust the output voltage of the regulated power supply so that
the digital voltmeter reading is 3.5 ± 0.1 V dc.
2) Turn off the power supply.
3) Turn on the HOLD switch of the adjustment remote
commander.
4) Turn on the power supply.
5) Load a cassette, and set the recording mode.
6) Select page: 0, address: 01, and set data: 01.
7) Decrease the output voltage of the regulated power supply so
that the digital voltmeter reading is 3.30 ± 0.01 V dc.
8) Select page: 2, address: 5D, read the data, and this data is named
Dref.
9) Set the read-out data (Dref) to page: D. address: 30 and press
the PAUSE button.
10) Convert Dref to decimal notation, and obtain Dref'. (Refer to
Table 5-4-1 “Hexadecimal-decimal Conversion Table” of “5-
4. Service Mode”.)
11) Calculate D31', D32', D33', D34' and D49' using following equations
(decimal calculation), convert it to a hexadecimal number, and
input each adjustment address.
Address: 31 D31' = Dref' + 3
Address: 32 D32' = Dref' + 10
Address: 33 D33' = Dref' + 10
Address: 34 D34' = Dref' + 10
Address: 49 D49' = Dref' + 13
Note: After setting each data, be sure to press the PAUSE button of
the adjustment remote commander.
12) Select page: 0, address: 01, and set data: 00.
