Figure 17 roughly describes the current consumption profile of the SARA-G300 and SARA-G310 modules (when
their EXT32K input is not fed by a signal, i.e. left unconnected), or the SARA-G340 and SARA-G350 modules
(‘00’ versions only), or the SARA-U2 modules, 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 17: VCC current consumption profile versus time of the SARA-G300 and SARA-G310 modules (when their EXT32K input is
not fed by a signal), or the SARA-G340 and SARA-G350 modules (‘00’ versions only), or the SARA-U2 modules, 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
For detailed modules’ VCC current consumption values in fixed active-mode (module registered with 2G / 3G
network with power saving disabled), see SARA-G3 series Data Sheet [1] and SARA-U2 series Data Sheet [2].
