Chamberlain Elite EWC485 User manual

Screw antennas on TIGHT.
Loose antennas will affect the signal strength!
Unlock the units and open doors.
Set both units to TEST MODE. ONLY test 2 units at a time, turn ALL other units OFF!
Set one unit to LOCAL connection and the other to REMOTE connection. The “LOCAL
connection” unit is near the telephone entry system.
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 12VDC, weak batteries will produce undependable test results.
Both units must be set to the same FACILITY FREQUENCY. If they are not the same,
follow Step 5on the manual to set the frequencies on both units.
Connect the battery wires to the removable power connector. When BOTH
units have been powered up, a CONTINUOUS tone will be heard from both
units indicating strong signals are being transmitted
and received.
Close and lock the units placing the LOCAL unit in
its final position near the telephone entry system.
Recommend minimum 8 feet above ground.
Take the REMOTE unit to the desired remote access
point and place it in its final position.
A continuous tone should be heard indicating that the range is OK.
The units can now be permanently installed in their current
positions.
Use the supplied transformer for permanent power. Discard battery pack.
Set the units back to OPERATING MODE.

Make sure the antennas are screwed on tight.
Try moving the remote unit 15-20 feet in several directions, away from metal surfaces or any obstructions.
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.
Test the battery packs with a voltmeter for 12VDC. Weak batteries will produce undependable test results.
Try changing the FACILITY FREQUENCY of the units. Follow Step 55 on the manual. Both units MUST be
set to the same frequency.
If a continuous tone is NOT heard during the range test:
