Attempting to operate the wireless intercom system through or
around walls, ceilings, metal objects, etc. reduces system range
and performance.
IMPORTANT: DO NOT mount the base station 1/2-
wave antennas on or next to: metal, such
as beams; walls with metal studs; or
equipment racks, etc. This also applies to
antennas assembled directly to the Base
Station. Mounting antennas near metal
detunes the antennas, which can result in
noise or loss of RF signal at the Base
Station. See Figure 17.
