RF MODULE (Receiver)
The RF Module was designed for installation within the
Pro EX 2.0 controller cabinet therefore providing permanent
placement and maximum protection. Many factors influence
operating range. Listed below are options to consider to
assure you experience the maximum range possible.
1.Do not install Pro EX 2.0 near large sources of metal such
as power meters, water pipes, and aluminum siding.
2.Do not install Pro EX 2.0 in a basement or underground location.
The higher the location the better chance of strong reception.
3.To receive maximum range in all directions, the antenna
should be pointed straight up. (vertical)
4.When operating the the remote, hold as vertical as possible
and face the direction of the receiver.

NO WIRING INSTALLATION OF THE RF MODULE
The Pro EX 2.0 Remote Control System was designed to
work right out of the box. Its “plug and play” installation
eliminates the need for complicated wiring and installation.
You’ll find no installation templets, lengthy tool list or the
need to drill any through-holes in any walls.
The RF Module receives and transmits communication
between the controller and remote. It has no wires
to connect and no batteries to replace because it is
powered by the controller once installed.
Installation is a simple three step process which only requires
a screwdriver.
STEP #1 Remove the protective pin connector cover located
at the rear of the controller face.
STEP #2 With the antenna pointing upward and to the right,
gently press the RF Module into the recess.
STEP #3 Finger tighten only using a Philips head screwdriver
the two mounting screws.
