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.
What to do if BLOCKED PROBE Indicator LED b and c flash fast on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment shows 'BLOCKED PROBE' and LEDs b and c flash rapidly, it indicates the probe is blocked, placed against the ear canal skin, or disconnected. To resolve this: * Examine the probe tip for contamination and replace it. * Reposition the probe. * Change the ear tip. * Check the probe connection with the base unit.
How to fix 'Printing Error No connection can be established with the printer' on AmpliVox?
If the AmpliVox Medical Equipment displays 'Printing Error' indicating no connection with the printer, try the following: * Restart the base unit. * Restart the printer. * Charge the printer. * Ensure the connection between the printer and the base unit is established.
What does it mean when WITHDRAW PROBE Indicator LED b and c flash fast on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment shows 'WITHDRAW PROBE' and LEDs b and c flash rapidly, it means the probe moved during measurement, or the test started with the probe already inserted. Reposition the probe to resolve this.
What does Volume outside range WITHDRAW PROBE Indicator LED b and c flash fast mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'VOLUME OUTSIDE RANGE' and LEDs b and c flash rapidly, it indicates the ear canal volume is greater than 5ml, or the probe isn't properly inserted. Reposition the probe.
What does Pressure lost WITHDRAW PROBE Indicator LED b and c flash fast mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'Pressure lost' and LEDs b and c flash rapidly, it means the ear seal broke during testing. Reposition the probe.
What does VOLUME OUTSIDE RANGE Indicator LED b and c flash mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'VOLUME OUTSIDE RANGE' and LEDs b and c flash, it means the probe isn't correctly placed in the ear canal. Reposition the probe.
What does PROBE NOT CLEAR Indicator LED c solid light mean on AmpliVox Medical Equipment?
If the AmpliVox Medical Equipment displays 'PROBE NOT CLEAR' and LED c is solid, it indicates the probe is blocked or incorrectly placed. Ensure the probe isn't in a test cavity at start-up and is free from obstructions.
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 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.
