Note: On first use the battery pack should be charged with an external power source (i.e. AC
Adapter) – 3 hours for the main battery and 7 hours for the backup battery. New main
battery packs alone must be charged prior to first use -- this process takes up to four
hours in an LXE Multi-Charger.

Note: Using the battery removal tool (or a coin) twist each fastener to the left to loosen the
battery pack. Twist the fastener to the right to tighten the battery pack.
Place the battery in the battery well, making sure the tabs on the bottom of the battery pack fit into
the slots at the bottom end of the battery well. Push the battery down into the battery well while
fastening the screws.
Fasten the screws tight enough to allow the rubber gasket to create a watertight seal. If the screws
do not easily twist into the threaded opening, remove the battery pack and repeat the process.
When the main battery pack is charging, the Battery Charge LED flashes green. The backup
battery is trickle-charged by the main battery. There is no backup battery charging indicator.
Whenever possible, use the AC power adapter with the MX5 to conserve the main battery and
charge the backup battery.

If the MX5 has a dead main battery and is as cold as the extended operating temperature’s
lowest value, the unit must be warmed to above –20°C (-4°F) before installing a new main battery
pack and pressing the On button.
