Operation; Adjusting Temperatures; Selecting Temperature Levels; Adjusting Stimulation Time - Atmos Varioair 3 Operating Instructions Manual

4.0 Operation

• Use the main switch to start the unit.
• Readiness for operation after 1 second.
• Completely press the hose tip onto the handle.
If the hose tip is not completely attached onto the handle,
!
damage could be caused to the patient's eardrum.

4.1 Adjusting temperatures

• Two variable temperature levels (20 °C ‒ 47 °C) (48 °C +
49 °C only for testing purposes).
) The lowest achievable stimulation temperature is approx.
2 °C over the ambient temperature.
• Temperature setting by coding switches (
- Left switch: for adjusting the "ten" partition
- Right switch: for adjusting the "one" partition
ª Lower keys (+): temperature increase
ª Upper keys (-): temperature decrease
• Standard settings:
- Level for cold stimulation: 30 °C
- Level for warm stimulation: 44 °C
Avoid bending the tip of the hose within the ear / auditory
!
canal. Otherwise, the error "F1" or "F7" may occur.

4.2 Selecting temperature levels

• For selecting the desired temperature level, use the
respective key (, , Fig. 1).
