Rapid blue flashes means the device is currently updating itself with new firmware.
A steady blue light mean that the device has received a configuration file from our
server and everything should be ok. This happens at the end of a successful
installation and at some point after a reboot of the device.

Test / Mute button light signals
When the 4th battery is inserted (either the first time you insert them or after
removing one and reinserting it), the test/mute button will flash blue and red once to
indicate that the device is booting up. This also occurs after the device has performed
a software upgrade.
After the device has powered up (first use or reboot) - it will check if it has a working
WiFi configuration. If it does not, it will go into installation/reconfiguration mode for
up to 3 minutes. During this WiFi check (and the possibly following installation mode)
it will be flashing blue. If you already installed your device, but the blue flashing
continues for more than 15 seconds - you need to check your WiFi settings.
