oximeters. The following table provides a brief description of each test. Use the
PLETH view for all functional testing.
Note:
The SRC-MAX selectable indicator LEDs may extinguish if there is a delay in proceeding
through the above tests. This is normal operation in order to increase the battery time.
Note:
Pressing a button on the SRC-MAX during the test procedures may be requested, changing a
certain parameter. If the SRC-MAX LEDs are not lit, press the button twice. Pressing the
button once causes the indicators to relight and pressing twice initiates the change.
