LOW BATTERY INDICATOR
When your hearing aid’s battery reaches a low power level, you will hear
a series of tones repeated every few minutes until the battery is replaced.
Only replace the battery when you hear the low battery tones every few
minutes. On average, you should have about seven to ten (7-10) days or
more of battery life per battery. We recommend that you be prepared
with backup batteries to avoid situations that leave your hearing at a loss.
NOTE:
Your hearing aid battery uses oxygen in the air to activate and release its charge.
Removing the battery tab initiates this process. A fresh battery needs a full minute
to air up so that it can reach a voltage level that is optimal for best performance
in the device.
STORING YOUR BATTERIES
When storing spare batteries, make sure you keep them in a dry,
moisture-free location. DO NOT place batteries in a refrigerator or
dehumidifying device, as the batteries could leak and harm your device.
Also, avoid having batteries touch each other, even with the tab attached.
Two batteries touching can cause them to discharge.
CAUTION: BATTERIES CAN BE HARMFUL IF SWALLOWED.
Be sure to keep batteries out of reach of small children, animals or persons of
diminished mental capacity. In the event a battery is accidentally swallowed, seek
prompt medical attention at the nearest emergency center, or call the National
Button Battery Hotline at (202) 625-3333.
DAY-TO-DAY OPERATIONS
TURNING YOUR DEVICE ON/OFF
Your hearing aid is automatically powered on whenever the battery door
is closed. To turn the device off, simply open the door and leave it open
until you are ready to use it again. As we mentioned before, leaving the
battery door open when not in use will dramatically lengthen the life of
your battery.
NOTE:
Your hearing device is programmed with a brief power-on delay. It’s normal to
take a few seconds for the device to become active.
