System check
The SYS CHK (SYS CHK0, SYS CHK1) message indicates that the Handle is doing a self-
check to ensure proper operation. The Handle will shut off upon completion of the test.
Press any button to power the Handle and clear the condition.
If these messages persist, the Handle requires service. Return the tympanometer to a
Welch Allyn service location for service. (See Service information.)
Data Transfer
When the DATA XFER message displays, the device has made the data connection to the
Printer/Charger. Any 226-Hz data stored in the Handle is now available for printing.
Note After each service, the device must be calibrated. Appropriate charges will apply
each time your tympanometer is calibrated.
