Remove the battery door by sliding it off
to the side of the MHA100.
To remove batteries turn the MHA100
upside down. The existing batteries will
drop from their slots.
The new batteries have a protective
covering and will not work unless the
covering is removed. Simply peel off the
covering using the tab and allow the
battery breathe for about 1 minute
before putting it into the MHA100.
