Control Panel: Understanding the Control Panel and LED lights
Outside Signal Level/RX Power LED Indicator Light States
General: Mobile networks, phones and data devices operate in two frequency bands
(800Mhz & 1900Mhz). The Stealth Booster will amplify signals in both bands if they are
present. The band that the phone or cellular data device will transmit (TX) and receive (RX)
on is determined by the cellular provider and cannot be chosen by the user. The booster
LED lights will indicate outside signal level and booster gain. The ‘Master Control’ button
on the control panel will allow the user the option to increase gain, decrease gain or shut
off one or both of the frequency bands.

Outside Signal LED lights: three orange LED lights for each frequency band indicate out-
side RX signal strength (base station power) being amplified by the booster and transmit-
ted into the building (Receive Power). This indicator is affected by two things : the outside
signal and attenuation that is applied by the user or the automatic controls of the booster.
The highest level signal being displayed by the booster lights can belong to any service
provider, not necessarily your service provider. To determine if your provider is the high
signal provider, start a call and place your phone at or close to the location of the donor
(outside) antenna and compare the phone signal bars to the LED indicator lights on the
booster. Note: if attenuation (gain reduction) has been applied by the automatic controls
of the booster or by the user, you may see low signal indication on the booster LED lights
even though the true outside signal is strong.
