3.5.3.  Turn off/Restart the Module 

Pull down PWRKEY for at least 1 s, and then choose to turn off the module when a prompt window comes 

up.   

 

Another way to restart the module is to drive PWRKEY low for at least 8 s. The module will execute forced 

restart.

 

The forced restart timing is illustrated in the following figure.

The  RTC  (Real  Time  Clock)  can  be  powered  by  an  external  power  source  through  VRTC  when  the 

module is powered down and there is no power supply for the VBAT. The external power source can be a 

rechargeable battery (such as coin cell) according to application demands. The following reference circuit 

design shows a design where an external battery is utilized to power RTC.
