The solid-state memory in the device functions much like an endless loop. When the memory fills up,
the unit begins overwriting the oldest locations with the latest data.
Each time the device 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. Animal SpO
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 have increments of 1 pulse per minute from 18 to 200 pulses per minute, and increments of
2 pulses per minute from 201 to 300 pulses per minute.
NOTE: The 9847V can not store pulse rates greater than 300 pulses per minute in memory. All
detected pulse rates greater than 300 pulses per minute are truncated and saved as 300 pulses
per minute in memory.
During data retrieval, the last data recorded is the first displayed. For example, the last 4 minutes of
data recorded are the first 4 minutes displayed.
Recording Sessions
Each time the device is turned on (except while setting the clock) data is automatically collected.
NOTE: Only recording sessions greater than 1 minute in length are kept in memory for later
printing.
Memory Playback Mode
1. With the unit off, press and hold Alarm Limit Review while pressing and then releasing On/
Standby.
2. Release Alarm Limit Review when 888 888 displays on the SpO
displays. Three brief beeps sound and ALr and dFt appear in the SpO
displays.
3. Data will be automatically played back from the memory.
NOTE: The keypad sequence for starting memory playback is identical to the sequence used for
entering setup mode.
