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.
