Operating Instructions

BTR-800, TR-800, TR-825 Initial Equipment Setup 23
Keep the distance between the base station and the beltpacks as
short as possible. The greater the distance, the weaker the signal.
Make sure the signal paths between the base station and
beltpacks are unobstructed. You should be able to visibly locate
the base station antennas at all times for best performance.
Attempting to operate the wireless intercom system through or
around walls, ceilings, metal objects, etc will reduce 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,
equipment racks, etc. This also applies to
the antennas when assembled directly to
the Base Station. This will detune the
antennas which can result in noise or loss
of RF signal at the Base Station, see
Figure 17.
