Replacing BTE, Mini BTE and Babyworn
Controller batteries
Standard Zinc Air or Silver Oxide / Alkaline
batteries
The BTE Controller uses three high power 675 Zinc Air batteries.
The Mini BTE Controller uses two. Silver Oxide or alkaline batteries
can also be used in very humid conditions: your BTE processor will
only operate for a few hours when Silver Oxide or alkaline batteries
are used.
�
Do not use rechargeable NiMH button cells (HB 116/054).
High Power 675 Zinc Air batteries are sealed, usually with a seal or
tab.
To change the batteries:
1. Remove the new set of batteries from their pack and make sure
the seals are removed.
2.
Let the new batteries stand for one minute, outside of their
packaging with their seals removed, to allow the air to activate
the batteries.
3. Turn off your processor.

If you are using the Babyworn wearing option, the BTE Controller
will need to be removed from the Babyworn Retention Case before
removing the batteries. See
Wearing the Babyworn Retention Case
for
more information.
