IV. OPERATING PROCEDURES
A.
Preparation for Testing
Turn the unit on by pressing the green power switch at the top left of the front
panel. The cool temperature will automatically be selected as indicated by
the illumination of the green LED next to the blue temperature select control.
Press the orange temperature select button if the warm temperature is to be
selected. The digital display will flash until the set temperature is reached. It
takes approximately 60 seconds for set temperatures to be reached when the
unit is first turned on. When the set temperature is reached (
±
0.5
°
C), the
temperature display will stop flashing and illuminate steadily. Note that the
flashing display does not preclude the user from stimulating the ear. If the set
temperature or flow time needs to be changed, see section IIIA for
instructions on how to use the front panel controls.
