1. LCD Display Screen. The device can automatic detect signal and real time display signal strength.
2. ALC/AGC (Automatic Gain Control): Ensure output level stable and adjustable continuously. Protect the device work stable.
1. Green light means work normally.
2. Reach full power, the ALC function start using and than show red light. Or the isolation is not enough, system come to self-excitation, also red light. It is time to decrease the gain manually.
3. Button “SEL” is for switch different system, Such as GSM+DCS dual band repeater.
Sys-1 stand for the first system-GSM, sys-2 stand for the second system-DCS.
User can push “SEL” to change system. And than push “+” “-”to adjust the gain.
If you want to decrease gain of DCS, Firstly, Push “SEL” to select sys2, than press the downlink "-" button to decay to the value you need.
As usual, downlink decrease how many dB gain, the uplink following.
On the contrary, push “+”button.
If you need decrease gain of GSM, Push “SLE” to select sys-1. Gain control same as above.
