(2) If multimeter does not indicate between +17.90 and +18.10 V dc, perform b (1) below.
(3) Connect multimeter to pin 4 on power plug and chassis ground (fig. 4).
(4) Multimeter will indicate between -17.50 and -18.50 V dc.
(5) Connect multimeter to pin 5 on power plug and chassis ground (fig. 4).
(6) Multimeter will indicate between -19.70 and -20.3 V dc.
(7) Connect multimeter to pin 3 on the remote jack and chassis ground (fig. 4).
(8) Multimeter will indicate between -15-90 and -16.10 V dc. Record indication.
(9) Connect multimeter to pin 2 on the remote jack and chassis ground (fig. 4).
(10) If multimeter does not indicate the same voltage, but of opposite polarity as
recorded in (8) above, perform b( 2) below.
b. Adjustments
(1) Adjust R9 (fig. 4) until multimeter indicates +18 V dc (R).
(2) Adjust R95 (fig. 5) until multimeter indicates the same voltage, but of opposite
polarity as recorded in (8) above (R).
