rfBee as arduino in low power mode, what can wake it up

HI all,

i am using rfbee in wireless sensor kit.
since batery is drained rather quickly I would like to go into low power mode. Is there any example how it should be implemented (on top of regular rfbee firmware)
Also if put in low power mode can rfBee be woken up by received rf transmission or it is ignoring possible RF traffic.
