PRECAUTIONS
• To measure blood pressure, the wrist must be squeezed
by the cuff hard enough to temporarily stop blood flow
through the artery. This may cause pain, numbness or a
temporary red mark to the wrist. This condition will appear
especially when measurement is repeated successively. Any
pain, numbness, or red marks will disappear with time.
• If you feel strong pain during the measurement, please
remove the cuff.
• Measuring blood pressure too frequently may cause harm
due to blood flow interference.
• Do not apply the cuff on wrist in which another medical
device is attached. The equipment may not function properly.
• People who have a severe circulatory deficit in the wrist
must consult a doctor before using the device, to avoid
medical problems.
• Do not self-diagnose the measurement results and
start treatment by yourself. Always consult your doctor for
evaluation of the results and treatment.
• Do not apply the cuff on wrist with an unhealed wound.
• Do not apply the cuff on wrist receiving an intravenous drip
or blood transfusion. It may cause injury.
• Do not use the device where flammable gases, such as
anesthetic gases are present. It may cause an explosion.
• Do not use the device in highly concentrated oxygen
environments, such as a high-pressure oxygen chamber or an
oxygen tent. It may cause a fire or explosion.
