How to change the spare batteryUpdated a year ago

To replace the spare battery in your Omni Ultimate+, follow these steps: 

1. Turn off the device. 
2. Peel back the rubber at the bottom of your Omni Ultimate+
3. Unscrew the 6 screws around the bottom of the device. 
4. Firmly pull the battery out from the bottom. 
5. You can now place the spare battery into the Ultimate+. Make sure you align the connectors on the correct side before insertion.

Note: All 6 screws are not necessary for regular use. The rubber casing does a good job of holding the spare battery in place.
