Configure Gain Setting
Step 4. Configure Gain Settings
If the red LED goes ON, it is the result of one of two factors.
1. More antenna separation is needed. Most likely, the easiest way to achieve this is to
move the magnetic mount antenna farther to the back of vehicle away from the inside
patch antenna.
2. Your vehicle is too close to a cell tower.
If unable to provide more antenna separation and the Alert LEDs flash after the initial
activation period, lower the dial above the blinking LED by 5dB (for example, from
50 to 40) and monitor the bars on your cell phone to see whether reception has improved.
Do not adjust the uplink and downlink dB attenuation settings more than 20dB. This could
cause a temporary shut down of the booster.
The booster case may become warm during operation. This is normal.
Press any key on your cell phone to refresh communication with the base station.
Warning.
The booster is rated for 5-15V input voltage. DO NOT use the booster with a higher voltage power supply. This can damage
the booster and/or cause personal injury.
