Battery Operation and Battery Charging Logic

When used in Media Player mode, VoIP Speaker Phone uses 3.7 V lithium ion (Li-ion)
batteries. They are automatically charged by the internal battery charger when connected
to USB.
Note: Only 3.7 V Li-ion rechargeable batteries may be used with the VoIP Speaker Phone.
Other types of batteries will require a different charging logic. For testing, VLSI Solution
has used 230 mAh batteries, which are approx. 30 17 4 mm and provide playback
time of 4. . . 5 hours when using earphones. For longer playback times use batteries with
a higher capacity.
IMPORTANT! Battery charging is performed by a chip not designed by VLSI
Solution Oy. While VLSI Solution has tested and measured battery charging
and have no reason to believe there are problems with it, VLSI Solution takes
absolutely no responsibility over the suitability or safety of it.
