Charging the Modem Battery Your modem’s lithium-ion battery is supplied discharged. For optimum
performance, you should charge it fully before use. If during use, the
Low battery indicator starts flashing red, the battery needs immediate
recharging or it should be swapped with a re-charged unit.
The modem battery is automatically recharged simultaneously with the
iPAQ when both units are inserted into the iPAQ Desktop Cradle (as
supplied with the iPAQ) or when directly connected to the mains
adaptor via the iPAQ serial port (depending on iPAQ model – refer to
your iPAQ user manual)
Follow the steps below to charge the iPAQ and modem’s battery:
1. Connect your iPAQ to the modem.
Slide the iPAQ into the desktop cradle.
2. Plug the iPAQ battery charger into a power source and the iPAQ
cradle. The iPAQ battery charging indicator on the iPAQ front
panel will flash when the iPAQ is charging and the battery
charging indicator on the rear face of the modem battery will also
flash when it is charging.
Note: Perform an overnight charge when charging the modem’s
battery for the first time.
3. When the iPAQ and battery charging indicators fully illuminate
both batteries are fully charged. If only one indicator fully
illuminates, only that corresponding battery is fully charged.
4. Remove the iPAQ and modem from the cradle when fully charged.
When the modem battery is fully charged, the internal charger stops
charging until the battery capacity falls below a certain value. The
battery charger will then automatically start recharging the batteries
again.
