Information about Swapping Battery Packs in ECO2.
Swapping Removable Batteries
ECO2 has an internal battery that is never removed from the case. There is also a removable battery behind the Battery Door on the right side of the case. You can check on the charge of each battery in the Battery Menu. With normal use of your device you will probably never have to remove the removable battery, but if you find that you are using your device to the extent that you can't keep your removable battery charged long enough for your use, you can purchase a second removable battery and battery charger from PRC. You can then keep a full battery handy and replace the low battery with the full one.
To Remove the Battery and Replace it with a Charged Battery
Remove the battery door on the right side of the case before you begin. You must press down on door with both thumbs and slide the door off the end of the case.
Pull on the battery tab that is attached to the end of the battery. The battery will slide out of the case.
Slide the replacement battery in so the pull-tab on one end is visible when the battery is in place.
Replace the battery door by lining it up on the case. Then place your thumb on the end of the door nearest the edge of the case and push the door into its slots. You may need to use the edge of the case for leverage. The door should fit tightly.
When you Remove the Battery Door
A yellow message box will appear on your display screen telling you that the battery door is off the case. The Battery Graph in the Status Display Area will show all red lines.
The removable battery will not work if the Battery Door is off. Your device will be powered solely by the internal battery which will give you must less battery life than when both batteries are working.
If the Battery Door remains off the case, the yellow message box will appear at intervals on your display screen. Eventually you will hear the low battery warning.
Always dispose of old batteries properly. Follow the regulations of your community, state or country.
