Check antenna connections to posts on the interface internal housing, to be sure that they are securely attached for both antenna sides.
|
2.
|
|
Ensure that the long axis of the interface case (or external antenna unit) is facing in the general direction of the audience.
|
3.
|
|
Elevate the interface or external antennas as far as possible above the plane of the distributed keypads.
|
4.
|
|
On a soft case interface without external antenna extensions, make sure that the short wire antennas are attached to the right and left posts on the internal housing, and the longer wire is attached to the center post.
|
Note:
|
|
Outdoor use of the Wireless Response System significantly reduces the range of the keypads. Antenna extensions should always be used in such cases.
