2.  Push the battery cover horizontally along the arrow shown in figure 3.

WARNINGS:

•  Battery polarities should be correctly installed,  

otherwise, damage may be caused to the equipment.

•  Please remove the batteries if the oximeter will be stored  

for more than 30 days.

•  Please remove the batteries if you want turn off the oximeter.  

Otherwise it is always in sleep mode.

•  Battery may leak or explode if used or disposed off improperly.

5 - OPERATING GUIDE

5.1 Application Method

1.  Remove the battery cover, and insert the two AAA batteries following polarity markings indicated 

inside of the battery compartment, then reposition the cover.

2.  Hold the oximeter with the display facing toward you, slide your finger into the opening probe of the 

device as shown below (Figure 4), until the fingertip touches the built-in stop guide. For best results, 

make sure the finger is centered within the finger guide.

3.  Press the button to activate the oximeter from sleep mode. The measurement interface will appear  

in 3 seconds.

4.  The measurement result will appear on the screen within 10 seconds.
5.  The oximeter will turn to sleep mode automatically within 8 seconds after the finger is removed.

5.2 Notes for Operation

•  The index finger, middle finger, and ring finger are suitable positions for the monitor.

•  Excessive or rapid movement may affect measurement.

•  Improper sensor placement may affect the measurement accuracy.

•  The oximeter can be reused after cleaning and disinfection.

•  The measurement is most accurate when the oximeter and the heart are at the same level.

•  (Only for Clearwave II) The plethysmogram can be used as signal quality indicator. 

  The displayed parameters might be unreliable with the disorderly plethysmogram.

•  (Only for Clearwave) The bar graph can be used as signal quality indicator. 

  The displayed parameters might be unreliable with un-periodic bar change.

•  The displayed parameters will show invalid indicator as ‘---’ if signal quality is very low.

•  The displayed parameters will show invalid indicator as ’---’ if oximeter fault occurs.
•  The oximeter will shut down after 5 minutes if continuous testing.

Probe LED Specifications

Thank you for purchasing the SureLife Pulse Oximeter. This manual contains the instructions necessary 

to operate the product safely and in accordance with its function and intended use. Observance of this 

manual is a prerequisite for proper product performance and correct operation and ensures patient and 

operator safety. Read this manual carefully before using the fingertip pulse oximeter. This product is a 

reusable medical device. The lifespan of the product is 2 years. This device is a prescription use device.

1 - SAFETY

1.1 Contraindications

Do NOT use oximeter in a magnetic resonance (MR) environment.

1.2 Warnings

Keep the oximeter away from young children. Small parts such as the battery door, battery, and lanyard 

may be choking hazards.

1.3 Cautions

•  Do not use the oximeter in the presense of flammable anesthetics. 

•  The oximeter needs to be used according to information provided in this user manual. 

•  The equipment is NOT intended for neonate and infant.

•   Do not use a damaged oximeter as it may affect measurement performance.

•   Do not place the oximeter on the same hand/arm when using a blood pressure monitor or cuff. 

•  Do not use the oximeter for more than 30 minutes without relocating the device to another finger.

•   Do not place the oximeter on edema or fragile tissues.

•   Do not use the oximeter as the only basis for making medical decisions, it is intended only to be used 

as additional information that you can give to your licensed health care professional.

•   Do not use the oximeter in high frequency environments such as near electro-surgical equipment.

•   Do not place the oximeter in liquid.

•   Follow local disposal and recycling laws for the oximeter and its components, including the batteries. 

•  Do not stare at the light (infrared is invisible) emitted from the oximeter as it is harmful to the eyes.

•   The oximeter is designed to measure the percentage of arterial oxygen saturation of functional 

hemoglobin. Any of the following conditions may reduce the performance of the oximeter:

 

- Flickering or very bright light 

- Moisture in the oximeter

 

- Body weight less than 10lbs 

- Weak pulse quality (low perfusion)

 

- Venous pulsations 

- Low hemoglobin

 

- Cardiogreen and other intra-vascular dyes 

- Carboxyhemoglobin

 

- Methemoglobin 

- Dysfunctional hemoglobin

 

- Artificial nails or fingernail polish

2 - THE BASICS

The pulse oxygen saturation is the percentage of HbO

2

 in the total Hb in the blood, so-called the O

2

 

concentration in the blood. It is an important bio-parameter for respiration. A number of diseases relating 

to the respiratory system may cause the decrease of SpO

2

 in the blood, furthermore, some other causes 

such as the malfunction of the human body’s self-adjustment, damages during surgery, and the injuries 

caused by some medical checkups would also lead to the difficulty of oxygen supply in human body. 

The corresponding symptoms would appear as a consequence, such as vertigo, impotence, vomit etc. 

Some symptoms may be serious enough to cause significant harm. Therefore, prompt information 

concerning the patients SpO

2

 can help doctors discover potential problems, and is of great importance  

in the clinical and medical field.

2.1 Principle

The Principle of the oximeter is as follows: an experience formula of data process is established making 

use of the Lambert Beer law according to Spectrum Absorption Characteristic of Reductive hemoglobin 

(Hb) and oxyhemoglobin (HbO

2

) in glow & near-infrared zones. The operation principle of the device 

is: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse 

Scanning Recording Technology, so that two beams of different wavelengths of light can be focused  

onto the human nail tip through a perspective clamp finger-type sensor. The signal is obtained and 

measured by a photosensitive element. The information acquired will be shown on screen through 

treatment in electronic circuits and microprocessor.

3 - INTRODUCTION

3.1 Intended Use

The Pulse Oximeter is a portable, convenient, non-invasive device, used to monitor arterial hemoglobin 

oxygen saturation (SpO

2

) and pulse rate. The personal application are adult patients (weight: >30lbs) and 

pediatric patients (weight: 20-30lbs). We recommend using the index finger, middle finger, or ring finger 

as suitable positions for the monitor. It is intended for spot-checking or attended-care monitoring in 

home health care and medical facilities.

WARNING:

•  This pulse oximeter is intended to be used only by clinical professionals or under their guidance.  

It must only be used by persons who have received adequate training in its use. Anyone unauthorized 

or untrained must not perform any operation on it.

CAUTIONS:

•  This pulse oximeter is intended for use in 

hospitals, clinical institutions, or healthcare communities.

•  The pulse oximeter is NOT designed for a newborn or infant. For adults and children, a finger thickness 

between 8 - 25.4mm is recommended.

NOTES:

•  The probe is the opening in the middle of the equipment in which the finger is inserted.

•  The probe is the Applied Part of the equipment.

3.2 Features

•  The pulse oximeter is small in size, lightweight, and easy to carry.

•  Low in power consumption,(600 spot-checks on two AAA batteries.)

•  Easy, one-button operation.

•  There are two modes: sleep and measure.

•  Automatic sleep mode after 8 seconds with no signal.

NOTES:

•  Press the power button to activate oximeter (measure mode) from sleep mode.
