Remark:
Increase the output power*---Recommended ways: adjust the outdoor antenna
direction/location, or replace with a higher gain antenna to increase input signal

fittings. Before using it, please confirm that your
Booster’s frequency
range is the same
as your service provider’s network, otherwise,

- A.Verify the receiving antenna if be damaged.
- B.Tighten all cable connections (be sure to hand-tighten only, do NOT use tools).
- C.Verify whether the outside and inside antennas connects to correct booster’s
port.
- D.Verify whether the booster’s frequency is corresponding with cell phone
frequency.
