Changing the battery
If you hear four rapid beep-tones while wearing your
hearing aid, it is an indication that the battery is near-
ly exhausted. Once the battery is totally exhausted,
the hearing aid will be completely silent. Exactly how
long the hearing aid will function after the beep-
tones varies from one case to another. We recom-
mend that you always have a spare battery with you.
Never leave an exhausted battery in the hearing aid.
Exhausted batteries may leak, which could damage
the hearing aid. When changing batteries, it is a good
idea to hold the hearing aid over a table or a carpet,
in case you drop the hearing aid or battery.
