Displays
Liquid crystal display (LCD): displays SpO
2
, pulse rate, and PIr values; updated
every second.
Pleth bar: seven-segment column that indicates the pulse rate and signal strength;
updated continuously. During monitoring, the lowest segment is always on.
Indicators (LCD icons): low battery and print
Backlight: edge-lit yellow light-emitting diode (LED)
Visibility without backlight: visible in normal light (fluorescent, 215 Lux) from
1.5 meters (5 feet) at 30° angle from above and 45° angle from the left, right, and
below
Visibility with backlight: visible in dark room from 0.6 meters (2 feet) at 30° angle
Power
Four 1.5V AA batteries (alkaline, rechargeable alkaline, NiCad, carbon, lithium, etc.)
Low battery indicator (screen icon)
Flashes on/off when battery power is low and fresh batteries are needed. The icon
continues to flash on/off until (1) the batteries are replaced, (2) no power is left to
power the oximeter, or (3) the oximeter is powered off.
The first time the icon flashes on/off, 10 to 60 minutes of battery life remains for
alkaline batteries when the oximeter has been operated at room temperature. The
time remaining for nonalkaline batteries is not predictable—the battery type
determines the capacity, operation time, and life cycle of the battery.
