FDA (Devices) recall action 79433
The FDA (Devices) publishes a recall like this one as 2 separate product records. They share a firm, a date and a cause; this page is all of them in one place, so the scale of the action is visible rather than spread across 2 pages.
The battery is integral to the device. If the device sits unused and is not charged for a lengthy period of time (a few months) the battery will go into a deep discharge state and the battery will expire. The battery may out-gas which may be described as swelled or puffed, as gas is trapped inside the pack surrounding the cells. This battery may cause the device case to separate a small amount.
The agency’s own wording, quoted from the enforcement report.
The unit total adds up the quantities the agency stated for each product. Where a product record gave no figure, or gave a weight rather than a count, it contributes nothing — so the real total is at least this, never less.
Dynavox Systems LLC is recalling 4,615 T10 Speech Generating Devices because the internal battery may swell and cause the device case to separate.
Dynavox Systems LLC is recalling 307 T15 Speech Generating Devices because the integral battery may out-gas and swell after long periods of disuse, potentially causing the device case to separate.
