INSTALLATION-SYSTEM DESCRIPTION
SECTION 200-096-202
FEBRUARY 1991
NOTE:
As of November 1989, the PSTU is equipped
with a jumperplug to change the ring genera-
tor no load output from 79OV peak-to-peak
square wave (high) to 130V peak-to-peak
square wave (low). The low setting is used
with peripherals that are sensitive to high-ring
voltage (almost all peripherals function with
high-ring voltage).
7 SYSTEM CONTROLS AND INDICATORS
7.00 System controls and indicators are located
inside the KSU. Controls and indicators may be
accessed only by removing the cabinet’s front
cover. Controls and indicators are located on the
power supply, KSU chassis, and on various PCBs.
