How can I perform hardware tests and what are the possible error messages?
Please refer to the manual, chapter 3.5.4.
The probe does not work properly – it seems to be always too loud!
Please use only the big ear tips together with the big probe tip during measurements and the small ear tips together with the small probe tip. Wrong combination of ear tip and probe tip will deteriorate your results. See also the advice in the accessory box. If in doubt, please perform a probe test as described in the manual, chapter 3.5.4 or contact your distributor.
The display remains black! What to do?
The display is deactivated after 2 minutes (power safe mode). Please touch the display to restart it. After 5 minutes without activity, the instrument powers down completely. Please press the ‘on-switch’ to restart.
My device needs calibration. What should I do?
Please contact your local service partner. You can find a list of service partners and their contact details here.
The display remains black or stalled – the device does not react at all!
Please restart the device by pressing the reset switch (see fig 3 in the manual). Please charge the battery if necessary. If the error is still present, please contact your distributor.
My device shows a “Touch screen error” message box during startup and then shuts down. What is wrong with my device?
Please check if there is any dirt/small particle between your display and your housing. Remove the dirt/small particle with a piece of thin paper.
My device shows a limited range of test modules since a firmware update / service / usage by others. How do I get the full list of modules back?
Please check if you can slide the screen left/right to switch between the “most recently used” list and the full list. You may configure the startup default in the settings/preferences dialog.
My device settings are locked and I cannot change any time / date or protocols. What is the password and reasoning behind this?
In order to prevent unintentional changes of the factory defaults / country specific defaults in the U.S.A., the devices’ settings are locked with a password. This password should be told to the supervisor only by the sales representative during the introduction. However sometimes this information is not provided. The password is: MOZART. Please contact your supervisor or sales representative if you need further information.
How to start Bone Conduction (BC) audiometry? / The license was upgraded to PTA 3 and BC audiometry is still not available.
To do BC audiometry the following prerequisites need to be met: - The “Audio Class 3” licenses is present (see “Activated Modules at Device Settings -> About Device -> Licenses Management) - BC connected at appropriate port: Grey for devices with SN 290000 and below, Red all other devices - Protocol “Expert” selected in the Audio module preset. You may reset the device to factory defaults after applying the license code enabling “Audio Class 3” and use the “Threshold” preset.
The device shows a message box on passed calibration although the last calibration was less than 1 year ago.
When pressing "Details" the device will tell why it complains. If it is because a transducer with passed calibration was connected you may simply delete the list by pressing the "x" button.
