[WIham] ST855

[Thomas Ruhlmann]

I recently acquired a motorola ST855 microphone tester with a broken wafer 
switch. I repaired the wafer and plan to use a wall wart for power rather than 
the 12 volts of mercury battery.

I have no motorola mic to test it with but would like to convert it to universal 
use. However, I have no literature etc on the unit.

Does anyone have any literature on this ST855 or is familiar with it's use?
