Nexus uses a battery door to control power.
- To turn Nexus on, insert a size 13 zinc-air battery, wait about 3 to 5 minutes after removing the tab, then close the battery door completely.
- To turn Nexus off, open the battery door.
Tip: Opening the battery door when you are not wearing the device helps preserve battery life.
