Optimizing the System
Setting RF Gain for Installation
Dynamic RF Power Control
By default, the MXW system automatically adjusts the RF power level based
on the distance between an APT and the microphones. This prevents signal
dropout if a microphone is taken outside of the radius of the coverage of the
current RF level.
Note: Greater RF coverage uses more battery power and decreases the
battery runtime. Additionally it increases the required distance between
systems.
RF Level and Coverage Area
Level 3: 100'
Level 2: 50'
Level 1: 25'
Manually Setting RF Power
You can limit the RF gain in order to maximize RF efficiency of a fixed space
and save microphone battery life.
There are three stages of RF gain in the APT for coverage over a range
of installation sizes: Level 3: 100' radius, Level 2: 50' radius, Level 1: 25'
radius. RF setting affects the microphone battery (higher level uses more
power, reducing battery runtime) and the system ability to reuse channels
in a space. Using a lower gain level decreases space the needed between
systems to avoid conflicting DECT frequency allotment.
