specified.
Troubleshooting
A general troubleshooting process is as follows: If
the
SRI10 is completely "dead," check the ac power
source and power supply output (34V at pin
M
of
printed circuit board). If the output is distorted,
low
or not present, apply an input signal as described
under
Ac
Voltage Measurements
below, and determine
that the input voltage to the board assembly is correct.
If an incorrect ac voltage is found on the board, per-
