How do I change the battery in the I-13 and I-16 device ?

The battery may only be replaced with a TDG G1 battery pack sold by Tobii Dynavox.

1. Place the device with the display facing down.
2. Unscrew the five (5) screws holding the battery cover in place with a Phillips screw driver.  Note: By design, the screws will not come loose from the battery cover.
3. Remove the battery cover plate.
4. Pull the Battery strap to remove the battery from the battery compartment.
5. Align the small green and white battery icons, one is located on the battery and one on the device, for the battery to be in the correct position.
6. Push the new battery into the battery compartment.
7. Place the battery cover back in place.
8. Tighten the five (5) screws with a Phillips screwdriver.
