What does Measurement timed out Indicator LED b and c flash fast mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'Measurement timed out' and LEDs b and c flash rapidly, it can happen when the ear seal check is set to EXTENDED, or the pump failed to achieve the starting pressure within 4 seconds, or the pressure failed to reach -400 daPa within 12 seconds. Reposition the probe and retry the test.
What to do if last measured data cannot be found under VIEW THE LAST TEST on AmpliVox Medical Equipment?
If last measured data cannot be found under VIEW THE LAST TEST on your AmpliVox Medical Equipment, it might be because NEW TEST was selected in between, deleting the last test from short-term memory. Ensure needed data is stored immediately.
What does WARNING! DEFAULTS RELOADED. Indicator LED c steady light mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'WARNING! DEFAULTS RELOADED' and LED c is steady, default configuration settings have been reloaded.
What does WARNING! DEVICE UNCALIBRATED. Indicator LED c steady light mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'WARNING! DEVICE UNCALIBRATED' and LED c is steady, it means one or more default values require recalibration before further tests.
Why is no reflex test conducted after tympanometry on my AmpliVox Medical Equipment?
If no reflex test is conducted after tympanometry on the AmpliVox Medical Equipment, even when the reflex test is active, check the REFLEX SELECTION settings. If the setting is ONLY IF PEAK IS FOUND or NEVER MEASURE, change it to your desired option.
How to restore my profile names on AmpliVox Medical Equipment?
If your profile names are gone on the AmpliVox Medical Equipment, it is because changing the operation language automatically defaults the profile names to the factory description. Re-name the profile again to fix this.
What does AIRFLOW ERROR RESTART THE UNIT Indicator LED c steady light mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'AIRFLOW ERROR RESTART THE UNIT' and LED c is steady, there is a fault with the air system or pump. Restart the unit.
What does AIRFLOW ERROR Indicator LED c steady light mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'AIRFLOW ERROR' and LED c is steady, there's a fault with the air system or pump, or the device cannot determine pump direction. Restart the unit.
What to do if no pressure can be obtained on AmpliVox Medical Equipment?
When the AmpliVox Medical Equipment shows 'No pressure can be obtained' and remains on the EQUALIZE PRESSURE SCREEN, it could be due to: * No seal being obtained. * Estimated volume being too high (perforated eardrum). * Wrong ear tip size being chosen. * Probe being blocked. To fix this: * Examine the probe tip for contamination and replace it. * Reposition the probe. * Change the ear tip.
Why does my AmpliVox Medical Equipment say 'WARNING! CALIBRATION EXPIRED'?
If the AmpliVox Medical Equipment displays a 'WARNING! CALIBRATION EXPIRED' message, it means the current date is past the calibration date. Verify the clock is set correctly. If the date is correct, recalibration is needed before performing further tests.
