Chapter 1 Safety Information
This chapter contains important safety information related to general
use of the Pulse Oximeter. Other important safety information appears
throughout the manual in sections that relate specifically to the
precautionary information.
Note
 Important! Before use, carefully read this manual, all safety
information and specifications.
 This device is not intended for home use.
 Federal Law (USA) restricts this device to sale by or on the order of
a physician.
 The Pulse Oximeter complies with Class-A requirements of the
EN55011 standard.
Warning
 This device is not intended as a device used for treatment
purposes.
 It is important for the hospital or organization that uses this
equipment to carry out a reasonable maintenance schedule.
Failure to do so may result in equipment failure, or injury to the
patient or operators.
 The Pulse Oximeter is intended only as an adjunct in patient
assessment. It must be used in conjunction with clinical signs and
symptoms.

Safety Information

Warning
 The Pulse Oximeter is to be operated only by medical doctors or
trained healthcare personnel to measure the SpO2 of clinical
patients (including adult, pediatric and neonatal patients) in
hospitals and healthcare agencies or in the process of transporting
patients.
 The Pulse Oximeter is designed for real-time and rapid
measurement of the patient’s SpO2. It is not suitable for long-time
continuous patient monitoring. Continual measurement must not
exceed 2 hours.
 Before using the Pulse Oximeter, the user should check and make
sure the device and its accessories can work properly and safely.
 When using the Pulse Oximeter together with the electrical surgery
equipment, the user should pay attention to and guarantee safety
of the patient being measured.
 To avoid fire or explosion hazards, do not use the Pulse Oximeter
at places where such flammable material as anesthesia gas is
present.
 Do not pull or lift the Pulse Oximeter by its connection cable. That
may lead to device falling and consequent patient injuries.
 It is not recommended to hang the Pulse Oximeter when
transporting patients. Safety hazards may arise from the large
amplitude swing during the transportation.
 Do not use the Pulse Oximeter or its sensor around working MRI
equipment. Induction current may lead to damages. The device
may affect operation of MRI equipment and vice versa.
 The Pulse Oximeter and its accessories may be contaminated by
microorganism during transporting, use and storage. Use the

Safety Information

recommended methods to sterilize and disinfect the Pulse
Oximeter or its accessories when the packing material is damaged,
or it has not been used for a long time.
Caution
 The Pulse Oximeter should be appropriately placed. Keep it from
falling, strong vibration or other mechanical damage.
 The Pulse Oximeter is a commonly sealed device. The user should
keep its surface dry and clean, and prevent any liquid from
infiltrating it.
 Don’t use mobile phones around when the Pulse Oximeter is in
operation.
 The Pulse Oximeter should only be maintained by personnel
approved by our company.
 Before use the Pulse Oximeter on patients, the user should be
familiar with its operation.

Chapter 2 General
2.1 Introduction
The Pulse Oximeter is a portable measuring device powered by
common or rechargeable batteries. It is compact, light, flexible to use
and easy to learn.
Parameters measured by the Pulse Oximeter include: arterial oxygen
saturation (SpO2), pulse rate (PR) and pulse strength. The Pulse
Oximeter measures these parameters through a SpO2sensor and
displays them on the LCD screen after certain further processing.
The Pulse Oximeter is operated and controlled by three buttons, which
are Power button, Backlight button and Confirm ID button. The Pulse
Oximeter is also capable of managing measured data and transmitting
the patient’s trend through the dual-purpose socket to a PC for printing.
2.2 Functions
The Pulse Oximeter has the following functions:
 Measuring: SpO2, PR and pulse strength;
 Prompting: Memory full, ID full, low battery, standby, and
technical error etc.
 Power managing: automatic standby, automatic shutdown;
 Data Managing: data storage, data protection, data deletion;
 Data Printing: patient information and trend data;
For the data printing function, you must install the Pulse Oximeter
management system in a PC equipped with a printer, and connect the
Pulse Oximeter with the PC by a communication cable.
