Each time the 920M PLUS is turned on, the current time/date information

(if the clock is set properly) is stored in memory to allow quick differentiation

of recording sessions. Patient SpO

and pulse rate are sampled and stored

every 4 seconds.

The oxygen saturation values are stored in 1% increments in the range of 0

to 100%. The stored pulse rate ranges from 18 to 300 pulses per minute. The

stored values are in increments of 1 pulse per minute in the interval from 18

to 200 pulses per minute, and increments of 2 pulses per minute in the

interval from 201 to 300 pulses per minute.

During data printing, the last data recorded are the first data printed. For

example, the last 4 minutes of data recorded would be the first 4 minutes of

printout.

Recording Sessions

Each time the 920M PLUS is turned on (except during setup mode) data are

automatically collected in memory.

Note: Only recording sessions greater than 1 minute in length are stored in

memory, and memory will be cleared approximately 2 minutes after

removing batteries. Replace batteries immediately to avoid losing

stored data.

Memory Playback

Note: Playing back data in memory does not clear any data from memory.

Note: The keypad sequence for starting memory playback is identical to the

sequence used for entering setup mode.

Playing Back Data Stored in 920M PLUS Memory

1. With the unit off, press and hold the advance switch while pressing

and then releasing the On/Standby switch .

2. Release the advance switch when is displayed on the SpO

and

pulse rate displays. The clock time currently set in the memory ( for

example) appears briefly in the displays, and then appears.

3. Data will be automatically played back from the memory. Data are

played back at a rate of 20 minutes of collected data per second. A

72-hour recording session (the maximum memory saved) is played back

in approximately 3.5 minutes.

4. After all data are played back, the 920M PLUS should be shut off

before collecting new patient data. The patient information is held in

memory as long as the batteries are sufficiently charged, so if the

memory must be cleared, use the memory clear function.
