2.2.1 The Battery
Omnii is powered by a Lithium-ion Smart Battery pack, 5000 mAh—Model No. ST3000.
Battery packs shipped from the factory are charged to approximately 40% and must be fully 
charged prior to use. Batteries can be charged using a variety of chargers and docking sta-
tions. For detailed information, see “Battery Details” on page 35.

Omnii On and Off” on page 15). If you do not turn the hand-held off before
