a.
No active visual and audio alarms.
b.
Saturation indication between 88 and 92 inclusive.
c.
BPM indication between 57 and 63.
d.
Pulse waveform of approximately half-inch P-T-P amplitude. Actual amplitude
may vary but references low pulse amplitude/high light indications.

alarm condition.
c.
BPM indication between 57 and 63 inclusive.
d.
Pulse waveform of approximately half-inch peak to peak (P-T-P) amplitude.
Actual amplitude may vary but will be a reference for low pulse amplitude/
high light indications.

Verify the MOD increase LED lights. The pulse amplitude waveform initially increases in
amplitude and then stabilize at P-T-P amplitude of approximately one-inch.
