1. CHARACTERISTICS AND FUNCTIONS
The high-quality finger pulse oximeter is designed for quick and non-invasive measurement of pulse
and blood saturation in both adults and children over four years of age. By monitoring the saturation
of hemoglobin with oxygen, various types of diseases and infections can be detected. For easier and
more accurate measurement, our company offers you a pulse oximeter that measures both
saturation and heart rate. It is extremely simple and convenient to use - just put it on your finger and
press one button.
It is a completely non-invasive and painless test that anyone can do on their own. It is enough for the
patient to put one of the fingers into the sensor for diagnosis, and the display screen after a few
seconds will show the directly measured value of the oxygen saturation of hemoglobin and the pulse.
• Measurement of blood oxygen saturation (SpO2).
• Heart rate measurement.
• Pulse intensity indicator.
• Bar and wave graph - display of heart rate.
• Clear, color, high-quality TFT display.
• Change the display direction.
• Convenient and easy one-key operation.
• Fast measurement.
• Small size, light, easy to carry.
• Very low battery consumption.
• Automatic switch-off after 5 sec.
• Lanyard.
CAUTION:
MESCOMP TECHNOLOGIES reserves the right to make changes to the hardware and software
resulting from technological progress.

2. PLEASE READ BEFORE TURN ON THE DEVICE
Please read the manual carefully before using this equipment.
Failure to follow these instructions could result in:
• measurement irregularities,
• damage to equipment,
• personal injury.
CAUTION:
The warranty for the devices does not cover damage from improper use, incompatible with the
user manual.
3. CAUTIONS OF USE
• Fingers that are too thin or too cold may affect the measurement result and cause the SpO2 and
pulse rate readings to be incorrect. In this case, insert a thick finger, such as a thumb or middle
finger, deep enough into the probe.
• Do not use the device on infants or neonates.
• The product is suitable for children over four years of age and adults (the weight should be
between 15 kg and 110 kg).
• The examined person must not have painted nails.
• The subject's nails must not be too long.
• If stable readings cannot be obtained, stop measuring. The device may not work properly for all
patients.
• If the screen displays abnormal indications during the test, pull your finger out and reinsert it to
restore normal operation.
• Read the measured value when the pulse waveform is normalized and the pulse waveform on the
screen is even and stable.
• Contact your doctor if the device is working properly and the indications are outside the norm.
Clinical limitations
• Factors that may cause inaccurate measurements:
o Poor heart rate
Significant pulsating blood flow is required for correct measurement. If you have a poor pulse due to
shock, low ambient / body temperature, heavy bleeding, or use of a vasoconstrictor drug, your SpO2
value will decrease.
o Anemia, low hemoglobin, toxic hypoxia.
If you have severe anemia, the device may show abnormal SpO2 measurements.
4
o A significant amount of a diluting dye e.g. methylene blue, indigo green and acid indigo blue or
carbon monoxide hemoglobin (COHB), methionine (Me + Hb) or hemoglobin, jaundice.
o Drugs such as dopamine, procaine, prilocaine, lidocaine and butacaine.
• It is not recommended to use the device if the patient is suffering from carbon monoxide
poisoning.
4. PRECAUTIONS
Before use, check the packaging to make sure that the device and accessories fully comply with
the description and instructions. Otherwise the device may malfunction.
Periodically check the main unit and all accessories. Make sure there are no visible damage that
may impact patient safety and monitor the performance of cables and transducers. It is
recommended to check the device at least once a week. Discontinue use of the device in the event of
obvious damage.
It is not recommended to use the oximeter in a high electromagnetic frequency environment.
Do not use the oximeter during MRI and CT examinations.
Do not use the device on people allergic to rubber.
Do not use the oximeter in an environment with flammable gases such as certain flammable
anesthetics. Using in these conditions may cause an explosion.
Do not disassemble or change the configuration on your own. Except as described in the
manual – SOLUTIONS OF EASY TROUBLE section.
CAUTION:
Do not repair the unit yourself. Necessary repair and maintenance work must ONLY be
performed by qualified service engineers. Users are not allowed to maintain or repair the device
themselves.
It is recommended that the sensor is not continuously applied to the same finger for more than
2 hours. Continued use of the device may cause an unpleasant or painful sensation, especially in
patients with a microcirculation barrier. The device must not be used on swollen, irritated or
oversensitive skin.

The light (infrared is invisible) emitted from the device is harmful to the eyes, so the user
cannot look at them.
This device is not intended for medical treatment. The device does not have an alarm function
with incorrect parameters.
Keep the oximeter away from dust, vibration, corrosive substances, explosives, heat, and
moisture.
Do not use the oximeter if it becomes wet. Do not immerse the oximeter in liquid. Do not
spray any liquid directly onto the device.
Do not use the oximeter immediately after it has been transferred from a cold environment to
a warm or humid environment.
Do not press the buttons on the front panel with sharp materials. The flexible circuit connects
the two parts of the device and should not be twisted or pulled.
Remove the batteries if the device is to be stored for more than a month, otherwise leakage
may occur.
The product lanyard is made of anti-allergic material. if the lanyard causes an allergic reaction,
stop using it. Do not wear a lanyard around your neck.
The device does not have low voltage alarm function, only shows low voltage, please replace
the battery when the battery power is used up.
