with devices not specified in User
Manual.
Cautions
Explosive hazard—DO NOT use the
oximeter in environment with
inflammable gas such as some ignitable
anesthetic agents.
DO NOT use the oximeter while the
testee is under MRI or CT scanning.
Warnings
An uncomfortable or painful feeling may
appear if using the oximeter continuously
on the same place for a long time,
especially for poor microcirculation
patients. It is recommended that the
oximeter should not be applied to the
same location for longer than 2 hours. If
any abnormal condition is found, please
change the position of oximeter.
DO NOT clip this device on edema or
tender tissue.
The light (the infrared light is invisible)
emitted from the device is harmful to the

eyes, so service technician or testee
should not stare at the light.
The local law must be followed when
disposing of the device.
Attentions
Keep the oximeter away from dust,
vibration, corrosive substances,
explosive materials, high temperature
and moisture.
The device should be kept out of the
reach of children.
If the oximeter gets wet, please stop
using it and do not resume operation
until it is dry. When it is carried from a
cold environment to a warm and humid
environment, please do not use it
immediately.
DO NOT operate the button on the front
panel with sharp materials.
DO NOT use high temperature or high
pressure steam disinfection on the
oximeter. Refer to Chapter 7 for
instructions of cleaning and disinfection.

rate value will be displayed on screen.
It is lightweight, small in size and easy to
carry;
Large bright LCD;
Accurately measure SpO2value and pulse
rate value;
Automatically start measuring after putting
finger into rubber cushions;
Power off automatically without signal for less
than 5 seconds;
Visible alarm function;
Low voltage indication;

pulse rate and functional oxygen saturation (SpO2)
through patient’s finger. It is applicable for
spot-checking SpO2and pulse rates of adult and
pediatric patients in home and clinics.
2 Battery Installation
Figure 3 Battery Installation
1. Refer to Figure 3, insert two AAA size batteries
into the battery compartment properly in the right
direction.
2. Replace the cover.

3 Operation
1. Open the clip as shown in Figure 4.
Figure 4 Put Finger into the Sensor
2. Put finger into the rubber cushions of the clip
(make sure the finger is in the right position),
and then clip the finger;
3. The device will power on automatically in 2
seconds and start to measure.
4. Measurement result will be displayed on the
screen (as shown in Figure 5). User can read
SpO2and HR values from display screen.
“%SpO2”: SpO2symbol
“”: Pulse beat icon;“BPM”: the unit of
pulse rate (beats per minute);
“”: Bargraph for pulsatile indication.

5. Change display direction.
Two directions display alternately. Press Display
Key once at a time, display screen will be flipped
180° each time in a cyclic manner. See Figure 6.
6. Alarm Indicator
When measuring, if SpO2value or pulse rate
value exceeds the preset alarm limit, the value
which exceeds limit on the screen will flash
(refer to Technical Specifications for alarm
limits).

4 Instructions for Operation
The finger should be put in properly and
correctly.
Do not shake the finger and keep at ease
during using.
Do not put wet finger directly into sensor.
Avoid placing the device on the same limb
which is wrapped with a cuff for blood
pressure measurement or during venous
infusion.
Do not let anything block the emitting light
from device.
Vigorous exercise and electrosurgical device
interference may affect the measuring
accuracy.
Using enamel or other makeup on the nail
may affect the accuracy of measurement.
If the first reading is unlikely true, the more
stable value is expected by waiting for a while,
or a restart is needed when necessary.
