cell phone cannot dial out. in this cases, cell phone signal booster can solve this problem in a certain 

extent. 

 

 

■ AGC(Automatic Gain Control):

 

When the downlink output signal is too strong or self-

 

oscillated, the 

uplink and downlink can automatically reduce the gain and reduce the interference signal 

 

■ Self- Oscillation elimination:

 

The system detects self- Oscillation, first reduces the link gain, then 

detects the loop, and finds that the self- oscillation is eliminated, the system returns to normal working 

state, otherwise, the power is turned off to prevent interference signal. 

 

■ Inactivity Mode:

 

When no user calls, the device is in standby mode, the uplink power amplifier is 

switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy saving.
