INSTALLATION
USEFUL INFORMATION
1. Must be mounted upright. Antenna must be up.
2. Radio Receivers are sensitive to heat. Avoid mounting them
above heater, air conditioner or exposed to afternoon sun.
3. The higher the Receiver Module, the longer its range. For
good range and reliable reception, install modules as high as
practical above ground level with antenna at top.
4. Large metal objects divert radio signals. Avoid mounting
Receiver Modules on metal wall, fence or near large metal
objects.
5. Environmental conditions could affect the operation of the
remote-control system. For example, in rain the range may
be less than normal.
6. Certain electric equipment like brush type motors or
electronic gas heater igniters emit radio signals and can
affect the function of the Receiver Module. Avoid mounting
modules near such equipment.
7. To prevent electronic interference, install Receiver Modules
at least 3 feet apart.
Make sure the intended load is within the capacity of the Module,
see ratings on page 1 and other model choices on page 3.
1. Securely attach Receiver Module to the top of an outdoor grade
junction box.
2. Select the proper location (see Useful Information above) and
install Receiver assembly on a vertical surface or other support,
using hardware, suitable for the purpose.
3. Prepare the necessary conduit runs as required by the installation
layout and pull in the specied conductors.
4. Follow wiring diagram A on the right, make wire connections as
shown.
5. Turn ON power and test installation, using the ON/OFF button on
face of the Receiver Module. Replace junction box cover, make
sure the installation is secure.
6. To link transmitter button with the receiver, see operation
instructions on page 3 or follow linking instructions provided with
RC939 transmitter.
