    3.5.1 Activating Sleep Mode By default, the G610 powers on in Idle Mode. The ATS24 default is 0. In this mode the G610 interfaces and features are functional and the module is fully active. Sleep mode is activated by the ATS24 command.

  • Page 20: Terminating Sleep Mode

    3.5.3 Terminating Sleep Mode Terminating the Sleep mode, or wake-up, is defined as the transition of the G610 operating state from Sleep mode to Idle mode. There are several ways to wake-up G610 from Sleep mode as described below. Important: During Sleep mode the G610 internal clocks and circuits are disabled, in order to minimize power consumption.
  • Page 21 During Sleep mode, G610 continues monitoring the GSM network for any incoming data, message or voice calls. When G610 receives an indication from the network that an incoming voice call, message or data is available, it automatically wakes up from Sleep mode to alert the application.

  • Page 22: Real Time Clock

    When the main power supply and VBACKUP is disconnected from G610, the RTC timer will reset and the current time and date will be lost. On the next G610 power-up the time and date will need to be set again automatically or manually.
