Important Note

If the Yanhua Mini ACDP displays the error "number of server calculations has exceeded the limit," this applies to DME types that require server-side calculation, including MSV90, MSV80, DPS6, and similar models. Each of these DMEs is limited to 6 server calculations before access is temporarily restricted. If this error appears, wait until the following day before attempting the operation again.
