Adjustment Procedure:
1 ) Remove the solder at RP-29 board pin
Q)
( REC C) as
shown in Fig. 3 - 1 4 so that the pin is completely off the
land, and input a 7 5 0 kHz, 0.4 ±0.0 1 Vp-p sine wave
from an RC oscillator.
2 ) Connect the oscilloscope t o RP-29 board pin
(?)
and
adjust to 4 2 mVp-p with RV5 08. ( Fig. 3 - 1 5 )
