Precautions
• When the AC adapter is used, make sure that the AC adapter can be
readily removed from the electrical outlet when necessary.
• Do not modify the monitor. It may cause accidents or damage to the
monitor.
• To measure blood pressure, the arm 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 arm.
This condition will appear especially when measurement is repeated
successively. Any pain, numbness, or red marks will disappear with
time.
• Take care to avoid accidental strangulation of babies or infants with
the hose.
• Do not twist the air hose during measurement. This may cause injury
due to continuous cuff pressure.
• Wireless communication devices, such as home networking devices,
mobile phones, cordless phones and their base stations, walkie-
talkies can affect this blood pressure monitor. Therefore, a minimum
distance of 30 cm (12") should be kept from such devices.
• Measuring blood pressure too frequently may cause harm due to
blood flow interference. Check that the operation of the monitor does
not result in prolonged impairment of blood circulation, when using
the monitor repeatedly.
• If you have had a mastectomy, please consult a doctor before using
the monitor.
• Do not let children use the monitor by themselves and do not use the
monitor in a place within the reach of infants. It may cause accidents
or damage.
• There are small parts that may cause a choking hazard if swallowed
by mistake by infants.
• Do not apply the cuff on an arm in which another medical device is
attached. The equipment may not function properly.
• People who have a severe circulatory deficit in the arm must consult
a doctor before using the monitor, to avoid medical problems.
