    10.1 Service and repair It is recommended that you keep the packing material in which MADSEN Xeta was delivered. If you need to send it in for service, the original packing material will ensure protection against damage during transport, etc.

  • Page 82: Calibration

    Clean the bone oscillator between patients, e.g. with a non-alcohol based antibacterial wipe, such as Audiowipes. 10.3 Calibration You can download new software to MADSEN Xeta, and if this involves no change to the transducers, MADSEN Xeta does not need recalibration. Annual calibration The audiometer, headphones, bone oscillators, and sound field speakers must be calibrated once a year by your authorized service department.

  • Page 83: Unpacking And Installing

    • Before you start using MADSEN Xeta, it is recommended that you leave it at room temperature for 30 minutes - par- ticularly if it has been stored at very cold or warm temperatures, e.g. if it has been in a car.
