Guardian Technologies WRT-30-A Manual De Usuario

 

Page 6 

 

 

 

The WRT-A is shipped from the factory set for DTMF (Tone) dialing mode.  If 
loop disconnect (Pulse) dialing is required proceed as follows.

 

•  Loosen the five captive screws in the faceplate and swing the faceplate to 

the left.  If the set is on a vertical surface the faceplate will stay open like a 
book in this position.  Take care not to disturb the internal wiring.

 

•  Change the position of the Tone/Pulse jumper on the circuit board to Pulse, 

as indicated on the label.

 

•  The set will now be in pulse dialing mode, it can be returned to tone mode 

by changing the position of the jumper back to the Tone position. 

•   Carefully replace the front plate and install all five screws.  Do not over 

tighten the cover screws, there is a flexible gasket between the cover and 
the body.  Excessive tightening of the screws deforms the gasket and 
reduces the weather resistance of the set.
