Basic Operation 9

Power On/Standby

Turn on the 920M PLUS by pressing and releasing the On/Standby

switch . Turn off the unit by pressing and holding this switch for about 2

seconds. Refer to Figure 2 on page 4 for a detailed illustration of the switches

and indicators. Refer to “Detailed Operation” on page 11 for detailed

information about entering setup mode and on general operation of the

920M PLUS.

Power On Self-Test

When the 920M PLUS is powered on for normal operation by pressing and

releasing the On/Standby switch , the unit will cycle through a startup (or

initialization) sequence before displaying valid data values.

During a startup, always check for any missing indicators or LED display

segments. If any indicator is not lit, do not use the 920M PLUS. Contact

Respironics Customer Support for repair or replacement.

At normal startup (when not entering the setup mode), with fresh batteries,

the 920M PLUS will cycle through the following sequence:

• will appear briefly in the SpO

and pulse rate displays

• the yellow low battery indicator will turn on steadily for a few seconds

• the pulse quality indicator will turn on red for 1 second, then green for 1

second, and then begin to blink

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

example) appears briefly in the displays

• the software revision number (the letter “r” followed by a 3-digit number,

for example) appears briefly in the displays

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

detected

Note: When entering setup mode at power on (for memory clear, calendar, or

clock settings), the 920M PLUS will cycle through a startup sequence

similar to the above, with the following exceptions: 1) The pulse quality

indicator will first turn on red for 1 second, then green for 1 second, but

will then turn off and not blink until after exiting setup mode; 2) the

software revision number will not appear; and 3) the two dashes will

appear only after exiting setup mode.
