expressed as ± "X" digits. Pulse oximeter equipment measurements are statistically
distributed; about two-thirds of pulse oximeter measurements can be expected to fall in
this accuracy (A ) range. Because scatter and bias of pulse oximeter SpO

specifications are calculated from data spanning the stated range, different accuracy
values may result when described partially overlapping ranges.

Specification applies to N-600x monitor performance. Reading accuracy in the presence
of low perfusion (detected IR pulse modulation amplitude 0.03% - 1.5%) was validated
using signals supplied by a patient simulator. SpO

Battery
The battery provides at least 7 hours of battery life when new and fully-charged with no
alarms, no serial data, no analog output, no nurse call output, with backlight on while
using a pulse simulator set for 200 bpm, high light and low modulation.
