-  Using the device for long periods may cause pain for people 
with circulatory disorders. Reposition the device at least once 
every 4 hours to allow the patient’s skin to breath and to check 
patient’s condition regularly.
-  Do not use the device near flammable or explosive gas mixtures.
-  Do not use the device during an MRI or CT scan, be used no 
closer than 30 cm (12 inches) to any part of the SpO2 device, 
including cables specified by the manufacturer.
-  The device may not work when circulation is reduced. Warm or 
rub the finger, or re-position the device.
-  This device is a precision electronic instrument and must be 
repaired by qualified technical professionals. Field repair of the 
device is not possible. Do no attempt to open the case or repair 
the electronics. Opening the case may damage the device and 
void the warranty.
-  Do not overextend the device’s spring. 
-  A functional tester cannot be used to access the accuracy of a 
pulse oximeter monitor.
-  Do not self-diagnose or self-medicate on the basis of the 
measurements without consulting your doctor. In particular, do 
not start taking any new medication or change the type and/
or dosage of any existing medication without prior approval.
-   Do not look directly inside the housing during the measurement. 
The red light and the invisible infra-red light in the pulse 
oximeter are harmful to your eyes.
-  This device is not intended for use by people (including 
children) with restricted physical, sensory or mental skills or a 
lack of experience and/or a lack of knowledge, unless they are 
supervised by a person who has responsibility for their safety 
or they receive instructions from this person on how to use the 
device. Children should be supervised around the device to 
ensure they do not play with it.
-  Neither of the displays for the pulse wave and pulse bar allows 
the strength of the pulse or circulation to be evaluated at the 
measurement site. Rather, they are exclusively used to display 
the current signal variation at the measurement site and do not 
enable reliable diagnostics for the pulse.
-  The maximum temperature of sensors which the user will touch 
might reach 43°C when operating in the 40°C environment. 
-  The safety for user use in high-temperature environment is 
measuring for 10 minutes, and turn it off for 20 minutes before 
measure again.
-  The oximeter is calibrated in the factory before sale. There is no 
need to calibrate during its life cycle.
Cleaning
Troubleshooting
Specification
