1 Safety 1.1 Instructions for safe operations � � � � Check the main unit and all accessories periodically to make sure that there is no visible damage that may affect patient’s safety and monitoring performance about cables and transducers. It is recommended that the device should be inspected once a week at least. When there is obvious damage, stop using the monitor. Necessary maintenance must be performed by qualified service engineers ONLY. Users are not permitted to maintain it by themselves.
␇ ␇ ␇ The device may not work for all patients. If you are unable to achieve stable readings, discontinue use. The update period of data is less than 5 seconds, which is changeable according to different individual pulse rate. If some abnormal conditions appear on the screen during test process, pull out the finger and reinsert to restore normal use. ␇ ␇ The device has normal useful life for three years since the first electrified use.
� seconds. Low‐battery indicator as battery icon flash manner. 2.3 Major applications and scope of application The Pulse Oximeter can be used to measure human Hemoglobin Saturation and pulse rate through finger, and indicate the pulse intensity by the bar-display. The product is suitable for use in family, hospital（Ordinary sickroom ）, Oxygen Bar, social medical organizations and also the measure of saturation oxygen and pulse rate.
3.2 Caution 1. 2. 3. 4. 5. 6. 7. The finger should be placed properly (see the attached illustration of this manual ,Figure 5), or else it may cause inaccurate measurement. The SpO2 sensor and photoelectric receiving tube should be arranged in a way with the subject’s arteriole in a position there between． The SpO2 sensor should not be used at a location or limb tied with arterial canal or blood pressure cuff or receiving intravenous injection.
4. 8 It is equipped with a function switch. The Oximeter can be powered off in case no finger is the Oximeter within 5 seconds. 4.9 Optical Sensor Red light (wavelength is 660nm，6.65mW) Infrared (wavelength is 880nm, 6.75mW) 5 Accessories � � � One hanging rope; Two batteries; One User Manual. 6 Installation 6.1 View of the front panel Figure 2.

� � Please take out the batteries if the oximeter is not in use for a long time. The best storage environment of the device is - 40ºC to 60ºC ambient temperature and not higher than 95% relative humidity. The device needs to be calibrated once a year (or according to the calibrating program of hospital). It also can be performed at the state-appointed agent or just contact us for calibration. High-pressure sterilization cannot be used on the device. Do not immerse the device in liquid liquid..
