Turning the GSM500 M2M device on

Power the GSM500 M2M.

Wait 30 seconds after power-up to give time to the GSM500 M2M
to register correctly with the GSM network.

Make sure the red LED (device status) flashes briefly once every 3
seconds as shown in chapter “SIGNALS” (see page 22).
If the red LED flashes quicker and stays lit for a longer time (see page 22), the
GSM device has not properly registered with the GSM provider:

Disconnect GSM500 M2M and make sure the SIM card is inserted
correctly and that the PIN is not locking it.

See chapter “PROBLEM-DETECTION GUIDE” (page 24).
