Product Description

        GSM 900MHz Cell Phone Cellular Booster Mobile Signal Amplifier Repeater

Model: GW-23G-V

Introduction                                                                                                              

Indoor Signal Booster series is an ideal solution for small/medium businesses and home users looking
to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service
Antenna, Donor Antenna is placed outside the building where it has easy access to a BTS signal, and the
Service Antenna is placed in the building where it can extend radio coverage to the blind area.

About POWER, Signal Bar, ISO, UL, DL indicators.

POWER LED	Green	Normal
	Off	DC power problem
Signal Bar	Off	Output power too small
Signal Bar	Green	Normal working
	Red	Working at Maximum ouput power
UL	Manual gain control of Uplink, 1=4dB, 2=8dB  Decrease 4dB, put down 1  Decrease 8dB, putdown 2  Decrease 12dB, putdown 1+2 together
DL	Manual gain control of Uplink, 1=4dB, 2=8dB  Decrease 4dB, put down 1  Decrease 8dB, putdown 2  Decrease 12dB, putdown 1+2 together
ISO(ALARM LED)	Green	It is working in linearity.
	Red	There are strong input signals or severe self oscillation. Please adjust the gain to see if it's too strong input signals; After that, if it's still red, that means much closer distance between indoor and outdoor antenna, please put them in longer distance between antennas.
MGC	UL	Uplink Gain Control
	DL	Downlink Gain Control

FAQ                                                                                                                     

1. After installing booster signal not be very good, indoor signal coverage very small ?
   > Adjust outdoor antenna's location and direction
   > Change another high gain outdoor antenna
   > Check whether cables are connected well
   > Change more powerful repeater

2. Cell phone signal full bar, but communication quality bad ?
   > Much closer distance between indoor and outdor antenna, separate them with a longer distance.

3. After installing booster not only signal be good, but also more bad ?
  > Much closer distance between indoor and outdor antenna, separate them with a longer distance.

4. Working good for long time, suddenly signal bad ?
  >  Check whether outdoor cable connectors are flooded
  >  Check whether power light is working normally
  >  If cables are not flooded and power light is working normally, the booster should has problems and need to be sent back to factory for repair.
