How do I add a battery upgrade?
I purchased the rechargable battery upgrade for the Grace Digital Mondo. How do I install it?
According to this link there are only 3 screws visible from the exterior of the product, and two of them are sunken so as to not be immediately obvious. Scroll down to Background and Identification.
Presumably if you undo these the back may come off so as to allow insertion and connection of the battery.
This link may be of interest as it has mixed reviews about using the battery mode of operation.
