Safety

Safety warnings from the record.

A leak at a backup cylinder yoke can deplete the reserve gas that is needed if pipeline supply fails. Source
On the related A3 and A5, a software fault could apply previous settings instead of defaults or skip the start up leak test, so check settings at each start. Source

Not covered: No Mindray product page or manual was opened, so manufacturerUrl points to the FDA summary and errorCodes is empty. The 510(k) comparison table extracted out of order; values were matched to rows by position and should be checked against the PDF. Battery, gas supply pressure, weight and electrical data were not found. The A3/A5 recalls are a related product line and are used only as guidance, not as A7 recalls. Recall text was read through openFDA because FDA recall pages returned errors at drafting time.
