Every 3dB lower, the power level go down 50%. Every 6dB lower the power level
go down 75%, the coverage radius go down 50%.
The panel indicator is flashing or solid green:
1. Booster has CPU inside, it will do the
“Oscillation” test every time after power on.
When it detect the Oscillation is happening, it
will lower the gain of the relative band 1dB.
And then test again, see if the oscillation is
cancelled. If not it will lowered the gain 1dB
again. This cycle will continue.

Trouble Shooting: Status Light Flash or Solid green
2. If the gain of the band is lowered by CPU between 1~15dB, and the oscillate
stopped. The status indicator will flash 1~15 times for 2 cycles.
3. If the gain of the band is lowered by CPU between 16~25dB, and the oscillate
stopped. The status indicator will flash all the time.
4. If the CPU can not eliminate the oscillation after reducing the gain by 25dB, it will
shut down the corresponding band to stop the oscillation. The status light will
solid red.
Indicator Status Gain lowered What to do?
Flash 1 to 15
times( 2 cycle) 1~15 dB If your coverage is good and reception is good, you
can ignore the flash.
Flash all the time 15~25 dB Check and install the whole system again.
Solid red shut down Check and install the whole system again.
Meaning of indicator light
Microphone
Speaker Sp
Have you ever had the experience of putting the
microphone in front of the speaker and you'll
hear a loud noise?
1. Microphone receive sound which from the
speaker, and then send the sound to speaker;
2. Speaker boost the sound then broadcast the
bigger sound to microphone again;
3. The sound gets louder and louder, and
eventually it becomes noise.
