See page 43 or 44 of the manual (depending what revision you have).

You can send the 'PS0;'  command to tell the K3 to shut down and power
itself off.

Turning it back on is more fun... You can do this by grounding pin 8
on the ACC port. I added an extra transistor to my FSK interface to
allow me to do this by toggling the DTR line on the COM port it's
connected to.

The manual says that when you use the ACC port, you should power off
by sending the 'PS0;' command first, waiting at least 100ms, then
removing the grounding from pin 8, otherwise there's some risk to the
non-volatile memory. I'd like some clarification on this ... in my
experience, removing the grounding from pin 8 does NOT power the K3
off (or have any noticeable effect) ... so I'm not sure why the 'PS0;'
command has to happen first...
