What is signal finder mode?

Signal finder mode (SFM) is a feature that you can use to determine an install location that will provide the best cellular signal strength for a BZ Gateway. Knowing the ideal location within your environment can improve the installation process.

1. Hold the power button (a) for three to four seconds then release the power button to start Signal Finder Mode. 
   
   A white LED (b) will flash repeatedly to indicate you are in Signal Finder Mode (this mode will operate for three minutes or until you press the power button again).
   
   
    

2. To achieve the best connectivity, move the BZ Gateway around the install location until the white LED begins to quickly blink (a blinking red LED indicates a poor cellular signal). Maximum signal strength is represented with a white LED flash every 200ms (the faster the white LED blinks the stronger the cellular signal).

   SIGNAL STRENGTH	LED PATTERN	INDICATION
   0-3	red LED blinking (quick blinking <1 second)	Low signal strength range
   4-10	white LED blinking (quick blinking <1 second)	Good signal strength range
   N/A	red LED blinking every 4 seconds	The modem is booting and/or has no network coverage

3. Once a good location has been found, quickly press and release the power button to exit signal finder mode.
