Chapter 6: Trend Data
Description
Whenever the monitor is on, it stores one SpO
2
and one pulse rate reading every 4 seconds.
The stored readings are called trend data. The monitor remembers trend data for at least 12
hours of run-time, possibly more, depending upon battery condition.
A summary of trend data can be printed on the built-in printer or stored data can be
downloaded to a computer.
Trend data will be preserved for about one and a half minutes, without battery power, allowing
battery replacement without losing trend data.

2. Press and hold the F key, then turn the monitor on. Do not release the F key.

switch the unit into Verification Mode. See pg. 7-5 on use of F key for Paper Feed.
