Page 7: Description Of The Interfaces
“Technical data” . SIM card The GSM Module M1 must have a SIM card to operate in the GSM network. To install this card, press the yellow button to eject the carrier and insert the SIM in the carrier. -
Page 8: Installation / Startup
Brown Switching the GSM module on/off The GSM Module M1 switches on when a positive voltage of 5 - 24 V is applied to IG- NITION if a voltage of 8 - 24 V is simultaneously applied to POWER. The module switches off when a voltage of less than +1 V is applied to IGNITION. An existing call is correctly disconnected. -
Page 9: Overvoltage / Undervoltage
When installed, the M1 must be protected by a medium time-lag fuse with a nominal value of 1A or a fast fuse with a nominal value of 1.6 A. For vehicle installation the M1 must be directly connected to the battery. -
