How to put nRF9160 DK in deep sleep mode?

[Haifan]

I just bought the nRF9160 DK.   How do I put it in deep sleep mode?

Thanks.

Are you talking about system off mode? You can put the chip in system off mode by writing 1 to the SYSTEMOFF register. Not sure if there is another way.

I want to put it in deep sleep to make the battery last as long as possible.  The spec says Page 56:  IMCUOFF0( MCU off, modem off, no RAM retention, wake on GPIO and reset) has power consumption of 1.4uA.  How do I put it in this mode?  Thanks.

On page 56 of the manual, it says  the current consumption is 1.4uA in the mode IMCUOFF0  (MCU off, modem off, no RAM retention, wake on GPIO and reset).  How do I put it in this mode?  I have the eval kit.

Looks like there is a more detailed answer to your question here; devzone.nordicsemi.com/.../230141

 I'm also trying to enter SYSTEMOFF on my 9160 DK with no luck so far.

 Tried to follow the link but got Access Denied.

 Any chances to have the answer unlocked?
