connection” unit is near the telephone entry system.
6 Temporarily stick the supplied battery packs on the outside of each unit with the double stick
tape. Feed the wires through an existing hole on back of the unit. It is VERY important that BOTH
battery packs produce 12 Vdc, weak batteries will produce undependable test results.
If a continuous tone is NOT heard during the range test:
7 Both units must be set to the same FACILITY FREQUENCY. If they are not the same,
follow Step 55 on the manual to set the frequencies on both units.
Make sure the antennas are screwed on tight.

units have been powered up, a CONTINUOUS tone will be heard from both
units indicating strong signals are being transmitted
and received.
Try moving the local unit 15-20 feet in several directions.
Try raising the units up, above the rooftops if necessary to clear any obstacles. The higher the units, the
less interference they will encounter. Keep antenna clear from metal surfaces or any obstructions that can
weaken the signal strength.
9 Close and lock the units placing the LOCAL unit in
its final position near the telephone entry system.
Recommend minimum 8 feet above ground.

Test the battery packs with a voltmeter for 12 Vdc. Weak batteries will produce undependable test results.
