 Do not attempt to repair the Pulse Oximeter by yourself. Only
certified engineers should maintain and repair it.
 Change the contact position between the Oximeter probe and
the finger periodically if you are monitoring your SpO2 levels
and pulse rate for more than 2 hours.
 This product is not designed to be used by newborn babies.
 Seek for medical care if the measured value goes beyond the
normal range and you are sure that the instrument is not
 The pulse oximeter uses infrared light (invisible to your eyes) to
measure your SpO2 levels. Hence, please do not stare at the
light-emitting components of the Oximeter, as that could cause
harm and/or potentially blind your eyes.
 For details about clinical limitations and contraindications,
please carefully consult relevant medical literatures.
Warning: Close the battery cover when the instrument is in use.
