5. LED Diagnostics

Once the booster is properly installed and power is applied, both LEDs will turn on

followed by the green LED flashing. The green LED will flash while the booster

increases its gain to the optimum level. The red LED may also flash during this stage

while the gain is properly set on the booster. When power control is established, the

green LED will remain constantly on. You may see the green and red LEDs flash back

and forth; this is normal. In areas where the cellular network is adequate, the booster

will maintain a maximum power level acceptable for normal operation and prevent

overloading the wireless device, as well as keeping RF signal levels at a minimum for

a healthy environment. If the red LED is constantly on and the green LED is off,

the booster has detected a fault. The booster will shut down automatically and

restart. If the fault persists, reposition the antenna until normal operation is achieved.

Once normal operation is established, you may permanently mount the antennas in

the locations you chose in prior steps.

Diagnostic LED Definitions

1. Solid Green and Red - LED test, the unit is initializing

2. Solid Green - Normal Operation

3. Flashing Green - Normal Operation, increasing gain setting

4. Solid Green and Flashing Red - Normal Operation, decreasing gain setting

5. Solid Red and no Green - Fault Detected
