At power up, all B441 LEDs activate for
several seconds, indicating proper insertion.
The Signal LEDs then turn off until the
module registers on the cellular network.
Registering a new module might take up to 2
minutes.
Check the LED display to ensure a good
signal strength level, and adjust the antenna
location as required. The signal strength
LEDs momentarily turn off to indicate the
module has measured and updated the signal
strength status. Refer to
Table 3.1.
