Figure 10Figure 10 roughly describes the current consumption profile of SARA-G350 modules or the
current consumption profile of SARA-G300 / SARA-G310 modules when their EXT32K input is not fed
by a signal (left unconnected), when power saving is disabled: the module is registered with the network,
active-mode is maintained, and the receiver and the DSP are periodically activated to monitor the paging
channel for paging block reception.

Figure 10: VCC current consumption profile versus time of the SARA-G350 modules or the SARA-G300 / SARA-G310 modules (with the
EXT32K input pin not fed by any 32 kHz signal), when registered with the network, with power saving disabled:
the active-mode is always held, and the receiver and the DSP are periodically activated to monitor the paging channel
