Clear-Com DX Base Antenna - Manual (Page 3)

Tools Required:
Phillips (cross-point) screwdriver, size #2
Power drill and drill-bit set
Procedure:
The antenna extension kit allows either of the antennas to be mounted up to 30 feet (9.14
meters) from the base station for improved coverage. With the extension cable and mounting
bracket, an antenna can be mounted inside a window or outside for extended coverage. Install
the antenna extension kit as follows.
Lay out the enclosed 30 foot (9.14 meter) antenna cable, with its female connector near the
base station and its male connector at the proposed area where the antenna will be mounted.
Bend and align the cable to the desired position.
Remove electrical power from the base station.
Remove (unscrew) either antenna from the base station.
Screw the female antenna cable connector onto the base station antenna connector where the
antenna was removed.
NOTE: To minimize stress on the connector, bend the cable to line it up with the base station
antenna connector before connecting it.
Screw the removed antenna onto the male connector at the other end of the antenna cable.
Return electrical power to the base station.
Place the antenna in the area where improved performance is required, and walk test
transmission and reception with two people using COMMUNICATOR ® s (with fully charged
batteries), pressing button B to communicate with each other. Move the antenna around the
area while communicating, to determine the mounting location where the antenna will have the
best possible transmission and reception.
Hold the enclosed antenna mounting bracket against the wall at the desired mounting location
and mark the wall through the two screw holes in the bracket. It may be necessary to mount
the antenna high enough to avoid a safety hazard or possible damage to the antenna.
Remove the bracket from the wall and drill two 3 /
16
inch (4.76mm) holes in the wall at the
marked spots.
Insert the enclosed screw anchors into the holes.
Place the enclosed screws through the holes in the bracket and screw them into the two screw
anchors to secure the bracket to the wall.
Again remove electrical power from the base station.
Remove the antenna from the antenna cable. DO NOT remove the antenna cable from the base
station.
Unscrew the hexagonal nut from the antenna cable connector.
Insert the antenna cable connector through the hole in the mounting bracket as shown in
Figure 2, and screw the hexagonal nut onto the connector to secure it in place on the bracket.
NOTE: To minimize stress on the bracket, bend the cable to line it up with the bracket before
connecting it.
Replace the antenna on the cable connector mounted on the wall.
NOTE: The best transmission and reception may be achieved with the antenna perpendicular to
the wall. However, if it is a safety hazard or is likely to be bumped and damaged in that
position, it may be necessary for the antenna to be parallel to the wall.
Return electrical power to the base station and resume normal operation.
