PRODUCT FEATURES
1. High brightness LED display SpO
2. Low power consumption; battery-low indicator.
3. Two display modes.
4. Automatically power off ; 2 AAA alkaline batteries.
5. When no signal or low signal is detected, the pulse oximeter will power
off automatically in 8 seconds.
INTENDED USE
Fingertip pulse oximeter is a portable non-invasive device intended for
spot-checking of oxygen saturation of arterial hemoglobin (SpO
pulse rate of adult and pediatric patients in hospitals, hospital-type faci-
lities. It is not for continuous monitoring.
OPERATION INSTRUCTIONS
1. Install two AAA batteries according to the Battery Installation instructions.
2. Place one of your fingers into the rubber opening of the pulse oximeter.
3. Press the switch button one time on front panel to turn the pulse oximeter on.
4. Keep your hands still for the reading. Do not shake your finger during
the test. It is recommended that you do not move your body while
taking a reading.

5. Read the data from the display screen.
6. There are two display modes. After turining on the pulse oximeter, each
time you press the power swith, the pulse oximeter will switch to ano-
ther display modes (Figure 3).
EVALUATING MEASUREMENT RESULTS
Warning : The following table for evaluating your measurements does
NOT apply to people with certain pre-existing conditions (e.g. asthma,
heart failure, respiratory diseases) or whilst staying at altitudes above 1500
metres. If you have a pre-existing condition, always consult your doctor to
evaluate your measurements.

Note : The following table informs you of the effects of various altitudes on
oxygen saturation value and its impact on the human body. The following
table does NOT apply to people with certain pre-existing conditions (e.g.
asthma, heart failure, respiratory diseases etc.). People with pre-existing
conditions can show signs of illness (e.g. hypoxia) at lower altitudes.
