Power management - low battery state

[Jan-OK2]

How works in this tracker power management to prevent battery overdischarging? I tried to use tracker as long as possible and tracker worked with lion battery under 2V, then it periodicaly reset, as voltage was insufficient for CPU. Doesn't has it any threshold to going sleep mode or turn off?

Unfortunately there is no Power Management in Software.
We have functions to read out Battery Level, but there is no shutdown at the Moment.

Thanks for reply. The power consumption in sleep mode should be about 0,03mA, so it isn't heavy problem. But how to wake-up? If i press user button, device start to consumpt cca 3mA and make nothing. I have to press RST, then it starts normally, but with reseted settings (e.g. profile...). What's will happen in sleep mode, while pressing user button?
