BEFORE YOU BEGIN
To ensure proper functioning of the BHGR618 follow this setup
procedure.
For best operation:
1. Assign different channels to different remote units.
2. Insert batteries in remote units before doing so for the main
unit (see instructions for battery installation).
3. Place the main unit as close as possible to the remote unit,
reset the main unit after installing batteries. This will ensure
easier synchronization between the transmission and reception
of signals.
4. Position the remote unit and main unit within effective
transmission range, which, in usual circumstances, is 65 to
100 feet.

Note that the effective range is vastly affected by the building
materials and where the main and remote units are
positioned. Try various set-ups for best result.
Though the remote units are weather resistant, they should be
placed away from direct sunlight, rain or snow.
