modes.

Power Supply
The LXE MX3-CE uses two batteries for operation.
• A replaceable Lithium-Ion (Li-Ion) battery pack. The battery pack recharges while in
the MX3-CE with the computer in a powered cradle or with the optional external power
sources attached. The main battery pack can be removed from the MX3-CE and inserted
in the LXE Multi-Charger which simultaneously charges up to six battery packs in four
hours.
• An internal 50 mAh Nickel Cadmium (NiCd) backup battery. The backup battery is
recharged directly by the main battery when it is installed. Full charging of the backup
battery may take several hours. The recharging of the backup battery is automatically
controlled by the MX3-CE. The backup battery must be replaced by qualified service
personnel.
Optional AC adapters are available – external AC power supplies (US and International) and a
cigarette lighter adapter.
