NEC MOBILEPRO 900 - Manual (Page 18)

1-10 Getting Started
Before using the system for the first time,
charge the MobilePro continuously for 6 to10 hours to fully charge the
main battery. Allow the 6 to10 hours to pass even if the indicator light
changes from amber to green before the 6 to10 hours have passed.
To protect your data, do not use the system until the battery is fully
charged. Recharge the battery whenever the battery charging LED
lights amber.
You must repeat this full 10-hour charge cycle only if the battery
becomes fully discharged.
Connecting the AC Adapter
In addition to using the AC adapter to fully charge your main battery
for the first time, NEC Solutions America recommends using the AC
adapter when you:
! Recharge the main battery pack
! Use PC Cards or CompactFlash ™ cards
! Use the internal modem
! Keep your MobilePro on for long periods of time.
Follow these precautions whenever you use
the AC adapter and the MobilePro:
! When using the AC adapter, make sure the AC outlet is near the
MobilePro and is easily accessible.
! Keep the main battery installed when running on AC power.
! When communicating or sending transmissions for a long time, use
the AC adapter to conserve power.
Follow these steps to connect the AC adapter.
1. Insert the plug on the AC adapter cable into the AC power port on
the left side of the MobilePro (see the following figure).
