TM 262

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 result on the screen and
the print screen pushbutton is pressed, the printer will indicate "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 your Welch Allyn Service
Representative, giving him/her the exact error code number.

Sample Test Results

Figures 1 through 10 illustrate test results from sample TM 262 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 looking tracing but does not dramatically affect
the test results.
