Initial Setup Assembly & Installation
1-First make sure that no power is connected to the booster. Connect the inside antenna or cell phone holder,
the outside antenna and power supply to the booster. Please make sure to connect each item in to the
correct ports as indicated on the booster.
2-Place the antenna on the outside of the vehicle and keep it separated as far as possible from the inside
antenna or cell phone holder.
3-Turn the power switch to ON position and the single Green LED on the side of the unit will become Green
constant ON to indicate that pwr is reaching the unit and that the unit is turned on.
Operation: PLEASE NOTE: It is normal for the booster to be quite warm during cell phone "in use" state.
LED Light Indicators on
Panel Label:
There two orange LED lights, one for the 800MHz cellular band and one for the 1900MHz PCS band. LED
ON state indicates that the RX (Receive Signal) function of the band is functioning normally.
LED Off state indicates that the band is shut down.
There two Green LED lights, one for the 800MHz cellular band and one for the 1900MHz PCS band.
Solid ON state indicates that the TX (Transmit Signal) function of the indicated band is on and is at
maximum gain.
Flashing Green LED in either 800MHz or 1900MHz indicates gain reduction in that band
Each flash equals 3db reduction in gain. One flash represents a 3dB reduction, two flashes represents a
6dB reduction etc. until the total gain of the booster has been suppressed.
Causes of Flashing Green LED Lights:
1-If the outside antenna is located too close to the inside antenna or phone holder the booster will reduce
gain in order to suppress any oscillation (feedback loop) and the Green LED will flash. To achieve higher
gain or max gain further separation of the inside and outside antennas is required.
2-If the booster is close to a cellular tower (Strong cell tower signal ) it will automatically reduce its gain to
protect the network. This condition will change as the booster approaches or leaves a cellular tower. This
is normal and cannot be defeated or altered by the user.
