Slide the battery into the battery compartment until it is fully seated. The battery is keyed so that it cannot be
installed incorrectly. Make sure that the pull-tab on the battery is accessible and does not prevent the battery
cover from closing properly.
3 Re-install the battery cover with the locking tabs seated downward, and then push the cover forward.
It may take up to 12 hours to reach full charge when:
• The battery is installed for the first time.
• The battery is replaced.
• The battery is fully discharged.
