The pulse oximeter uses infrared light (invisible to your
eyes) to measure your SpO

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.
This pulse oximeter is not a medical device and is not
intended to diagnose or treat any medical condition or
disease. It is intended for non-medical use in healthy
people to monitor their pulse and blood oxygen levels
during sports and/or aviation only. People who need
SpO
2
and pulse rate measurements because of a medical
condition should not use the INV-430J/PE and should
consult with their physician.
For details about clinical limitations and contraindications,
please carefully consult relevant medical literatures.
