Product Safety Information 
 
 
When installing the transmitter, do not touch 
exposed contacts on the component board. 
 
 
When opening or closing the transmitter, avoid 
damaging the transmitter electronics with the 
two plastic supports on the bottom of the 
mounting base. 
 
 
Wire the transmitter according to the 
terminal label on the mounting base. 
Terminal layout depends on transmitter 
model, so do not mix mounting bases from 
different transmitter models. 
 
 
If you connect more than one transmitter to a 
single 24 VAC transformer, always connect the 
phase (~) to the +Vs connector in each 
transmitter. 
 
 
The trimmers only turn 135 degrees each way, 
less than half a rotation. Do not force the 
trimmer past the stopping point.
