Battery Installation
1. When using Zinc Air batteries*, remove adhesive tab
(IMAGE 1) on the Battery to activate. Allow Battery to sit
for a full minute prior to inserting into the HD Smart Ear
Battery Compartment.
NOTE: HD Smart Ear can also use alkaline batteries.
2. To open the Battery Compartment Door, find the notch
with your finger nail and pull outward to open the door
(IMAGE 2). Slide the Battery into the Battery Compartment
with the positive side facing up as marked on the Battery
Compartment frame (IMAGE 3).
3. Press the Battery Compartment Door closed until you hear
it snap shut (IMAGE 3). If the Battery door does not close
with ease, check to be sure the Battery has been placed
inside the Battery Compartment correctly.
NOTE: HD Smart Ear may use Zinc Air battery (P675) or an
Alkaline Battery (LR44). Zinc Air is best for frequent use,
Alkaline best for infrequent use.
* Zinc Air batteries will last roughly 30-45 days after tape is
removed, even if HD Smart Ear is turned off.
