Appendix A: Data Format

Appendix-2 Pulse Oximeter for Sleep Screening Operation Manual

The following table shows an example of data de-compression:

Byte in HEX De-compression

88 Marker byte, expect the next byte to be SpO2;

60 SpO2 value, HEX 60 equals to 96% SpO2 decimal, expect the next byte

to be Pulse Rate;

52 Pulse Rate, HEX 52 equals to 82 bpm decimal, expect the next byte to be

the byte divided into low and high nibbles;

f0 Low nibble is 0, SpO2 = 96% + 0 = 96%;

High nibble is –1, Pulse Rate = 82bpm – 1 = 81 bpm;

ef Low nibble is -1, SpO2 = 96% - 1 = 95%;

High nibble is –2, Pulse Rate = 82bpm – 2 = 80 bpm;

30 Low nibble is 0, SpO2 = 95% + 0 = 95%;

High nibble is 3, Pulse Rate = 80bpm + 3 = 83 bpm;

Note: Your service representative can supply an ANSI C de-compression routine.

Appendix B: Setting the Optional Real Time Clock

1. Clear trend memory by pressing and holding the print key at power up until CLR

stops flashing.

2. Turn the monitor off. Power on the monitor and continue to hold the on key for 6-8

7. Press the power key again to show the year setting. Use the print key to set the

desired year.

8. Press the power key again to exit the time setting menu. After the power key is

pressed a time stamp is printed and the monitor turns itself off.

9. Verify that the correct time stamp was printed. If the correct time and date was not

printed, repeat steps 2 through 9 until the proper time and date is verified.

The time and date can be verified by repeating step 2 and then pressing the print key until

the current time and date is printed and the monitor turns itself off.
