fessional.
2. MADSEN Astera² is intended for diagnostic and clinical use by audiologists and other trained health care professionals
in testing the hearing of their patients.
3. To prevent cross-infection, use new eartips when you test the next client.
4. Accidental damage and incorrect handling can have a negative effect on the functionality of the device. Contact your
supplier for advice.
5. For the sake of safety and in order not to void the warranty, service and repair of electro-medical equipment should
be carried out only by the equipment manufacturer or by service personnel at authorized workshops. In case of any
defects, make a detailed description of the defect(s) and contact your supplier. Do not use a defective device.
6. It is recommended to install the unit in an environment that minimizes the amount of static electricity. For example,
anti-static carpeting is recommended.
7. Do not store or operate the device at temperatures and humidity exceeding those stated in the Technical Spe-
cifications, Transport and storage.

12. The device and any device to be connected which has its own power supply should be turned off before any con-
nections are established.
To disconnect the device from the mains supply, pull the mains plug out of the wall mains
outlet. Do not position the unit so that it is difficult to pull the mains plug out of the wall mains.
13. For safety reasons and due to effects on EMC, accessories connected to the equipment's outlet fittings must be
identical to the type supplied with the system.
14. It is recommended that an annual calibration be performed on accessories containing transducers. Furthermore, it is
recommended that calibration be performed if the equipment has suffered any potential damage (e.g. headphones
dropped on the floor).
