by pushing the catch
and open the cover.
Remove the battery.
Insert a new AAA size battery as shown.
Close the battery compartment
. The battery
compartment cover locks into place with an audible click.
Always replace the two batteries at the same time.
Remove the batteries from the battery
compartments
if the headset will not be used for
extended periods of time.
