A tempered glass window requires the use of the supplied magnetic

wand/screwdriver to activate the four user interface switches that

are located on the front of the display module. This allows for non-

intrusive setup and operation.

A locking screw integrated into the cover provides positive

scription of all of the parts that are shipped with the transmitter.
