ANTENNA POLARIZATION
The Telex Wireless Intercom System is “Ver-
tically Polarized”. This means both the trans-
mitting and receiving antennas should operate
in the vertical position.

ANTENNA PLACEMENT
Proper antenna placement probably has the
most effect on you TELEX Wireless intercom
System’s overall performance. The following
suggestions will result in optimum perfor-
mance.
Proper placement of the TR-300 can be criti-
cal. The trailing antennas should “dangle”
freely. “Wadding” the antennas up and placing
them in a pocket, etc., will reduce system
range.
It is suggested that the unit be worn on the belt
or pocket with both antenna’s hung vertically
for best operating range and performance.

(BTR-300) and the belt pack (TR-300) anten-
nas as short as possible. The greater the dis-
tance, the weaker the signal. However, the
portables should be a minimum distance of 10
feet from the base station and each other for
best performance.
Make sure the “signal paths” between the
BTR-300 and remotes are unobstructed. You
should always be able to visibly locate the an-
tennas for best performance.
