Batteries shipped from the factory are charged to approximately 40% of capacity. Lithium-
ion battery packs must be fully charged before use. These batteries can be charged with a
variety of chargers and docking stations. Currently the following are available:
•
The Snap Module is a mobile adaptor for Omnii. Three models are available—see
•
The AC Wall Adaptor operates as an AC power source and also charges the battery
installed in the unit—see “AC Wall Adaptor - Model No. ST1050” on page 179.
•
The Vehicle Power Outlet Adaptor powers Omnii and recharges the battery using power
drawn from your vehicle’s automotive power outlet—see “Vehicle Power Outlet
Adaptor - Model ST3113” on page 179.
•
The Desktop Docking Stations operate as both chargers and docking stations. Operating
as a charger, both the battery installed in Omnii and a spare battery can be charged. Pri-
ority is given to charging the hand-held's battery. See “Desktop Docking Stations -
Models ST4002 and ST4003” on page 180.
Normally it takes 3 to 4 hours to charge a battery. The Omnii intelligent charging system
protects the battery from over-charging by terminating the charge process when the battery
is at maximum capacity.

Installation—Chargers and Docking Stations
When installing a charger or docking station, consider the following guidelines.
•
Keep chargers and docking stations away from excessive dirt, dust and contaminants.
