Power On Self-Test

When the Model 920M PLUS is turned on for normal operation, the unit

will cycle through a startup/initialization sequence before displaying valid

data. During startup, always check for any missing indicators or LED

display segments. If any indicator is not functioning, do not use the device.

Contact Respironics’ Technical Service for repair or replacement.

During its normal startup sequence, the device will cycle as follows:

•“888 888” appears briefly in the SpO

and Pulse Rate displays.

• the amber Low Battery LED turns on steadily for a few seconds.

• the Pulse Quality display turns red for 1 second, then green for

1 second, then shuts off.

• the clock time currently set in the memory (in hours and minutes,

04 41 for example) appears briefly in the displays.

• the software revision numbers (display in the following order, each for

approximately 1 second): Main revision “r” + 3 digit; Memory revision

“n” “n” (for m) + 3 digits.

• (two dashes) appear in the displays until a valid pulse signal is

detected.

NOTE: This startup sequence varies slightly when entering setup mode

at power on.
