ear, masking in the other ear is switched off.
NOTE: Once the default settings are changed, the device applies the new settings.
Reset the device to return to the default settings.
The display has an energy saving function; the backlight of the display is automatically
dimmed after approximately three minutes. Any action with the MA 41, such as pressing
a button or rotating the dial, immediately illuminates the backlight.

Measurement Methods of Audiometry

The patient should sit at a distance of at least 1 m from the device.
Remove any obstructions that interferes with the earphone cushion placement over the
ear (e.g. hats, eyeglasses). Always use the headphones with appropriate padded ear
cushions.
Ensure the headphones are placed correctly over the patient's ears and that the red side
is over the right ear and the blue side is over the left ear. Adjust the headband of the
headphones so that the receivers are at the correct height (the sound output grid on the
inside of the headphone should be directly over the ear canal).
Ask the patient to press the button on the patient response switch when the tone is heard,
even if it is barely audible.
For hygienic reasons it is important to clean and disinfect the ear cushions on the
headphone between patients (see Section 3.3).
