Charging A Spare Battery

•Slide NEO into the docking station, making certain that the connector on the base of the hand-held is securely seated on the docking station connector pins. An icon is displayed in the task bar at the bottom of the hand-held screen indicating that the unit is properly installed in the station:

The LED on NEO lights up indicating that the unit has external power and battery charging will begin. It is safe to leave the unit in the desktop docking station while it is not in use – the battery will not be overcharged.

Note: To maintain the NEO real time clock for three days, the battery must be charged for a minimum of two hours (while installed in the hand-held).

6.5.3Charging A Spare Battery

To charge a spare battery:

•Insert the battery in the spare battery charge well at the back of the docking station, aligning the contacts on the battery with the contacts in the spare battery charge well.

Note: To maintain the NEO real time clock for three days, a battery must be charged for at least two hours while installed in the hand-held; however, if you are charging a spare battery (not installed in the hand-held), the real time clock three day backup cannot be maintained until a charged battery is installed in the hand-held computer for at least two hours.

6.5.4Battery Charge Duration

A NEO inserted in the desktop docking station requires 3 hours to charge the battery to 75% capacity.

Note: The specified battery charge times are based on NEO default settings – i.e., display brightness 50%, keyboard backlight off, 802.11b/g radio on and 23° C temperature. Additional peripherals and other power consumption features will also alter the specified charge time.

The desktop docking station stops applying power to the battery when it is fully charged– there is no risk of overcharge if the battery remains in the charge well.

6.5.5Docking Station Charger LED Indicators

The desktop docking station is equipped with a single tri-coloured LED indicator in the lower-right corner of the front panel that indicates various charge states of the spare battery installed in the docking station.
