BEFORE YOU BEGIN
For best operation,
1. Assign different channels to different remote units.
2. Insert batteries for remote units before doing so for the main
unit.
3. Place the main unit as close as possible next 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 trans-
mission range, which, in usual circumstances, is 20 to 30
meters.
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 proof, they should be
placed away from direct sunlight, rain or snow.
