Does one have to do anything to turn it off and save battery when not in use?

After the sensor is properly worn, it will automatically turn on, the front LED flashes (turns off after 10 times). * Note: The red light indicates that the monitor is ready to use.

Will this connect with Nu Step cross trainer?

It syncs with all my set ups - Garmin, Wahoo and my Schwinn Carbon Blue Spin bike computer (who know who made that)

Will this connect to the cardio machines at the gym?
