Special Messages and Error Codes
Error code numbers and other special messages may be displayed on the screen or on
the printout. These messages appear whenever an instrument error occurs or, in some
instances, to apprise the operator of certain situations. For example, if there is no test

"No Test To Print".
Error codes will appear as a two-digit number prefixed by the letter "E". If an error code
appears, please repeat the operation that caused the error code to appear. If the error
code appears for the second time, make a note of it and contact a Welch Allyn service
representative, and give him/her the exact error code number.
Sample Test Results
The following figures illustrate test results from sample TM286 Auto Tymp printouts. The
smoothness of the tympanogram tracing is determined by the amount of movement
during the testing. Little or no movement during the testing provides a smoother tracing.
Moving, talking or crying during testing leads to a more erratic traces but does not
dramatically affect the test results.
