When first switched on, the TEL50.GSM will require a few seconds to connect to the GSM network. During this initial stage, the
front LEDs may flash on and off and the GSM field LED flash quickly (one pulse every second). Connection to the GSM
network will be confirmed by the slow flashing of the red LED located in the bottom part of the device (one flash every 3
seconds approx.). Check that this occurs before going on to use the TEL50.GSM.
