Step 4. Turning on the hearing aid
Switch on the hearing aid by closing the battery
compartment (Fig. 4a).
I Open and close the battery compartment gently
and carefully.
I Check if you feel resistance when closing the
battery compartment. Check to make sure the
battery is correctly inserted and in the correct
direction. If the battery is inserted the wrong way,
the hearing aid will not work and the
battery compartment can be damaged.
