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).
