PRINCIPLE OF OPERATION
This device adopts the oscillometric technology with Fuzzy Algorithm measuring the arterial blood pres-
sure and pulse rate. The cuff is wrapped around the arm and automatically inflated by the air pump. The
sensor of the device catches weak fluctuation of the pressure in the cuff produced by extension and
contraction of the artery of the arm in response to each heartbeat. The amplitude of the pressure waves
is measured, converted in millimeters of the mercury column, and is displayed by digital value.
Annotation: This device can not provide reasonable accuracy if used or stored in the temper-
ature or humidity beyond the range stated in the section <SPECIFICATIONS> of this manual.
TIPS UN TAKING BLOOD PRESSURE MEASUREMENT
1. Generally arterial blood pressure is lower in summer and higher in winter. Arterial blood pressure
changes with atmosphere pressure and is affected considerably by many factors, e.g. physical loads,
emotional excitability. stress, meals, etc. Medicines, drinking, smoking affects greatly the level of
individual blood pressure. Blood pressure will raise in low temperature, so it is better to take blood
pressure measurement in room temperature (approximately 20°C). If this device was stored in low
temperature, it is necessary to leave it in room temperature for at least 1 hour, otherwise the meas-
urement can be inaccurate. Blood pressure does vary with age and individual, and it is recommended
to write down the readings in blood pressure record daily, then you can check with your doctor to find
out what is “normal blood pressure” for you.

2. Take measurement under doctor’s instruction for patients with cardio-vascular diseases.Under no
circumstances should you alter the dosages of any drugs prescribed by your doctor!
3. Accurate measurement of blood pressure may be difficult in serious arteriosclerosis, weak pulse, or
in patients with obvious fluctuation of heart contraction rhythm. Please consult qualified physician
interpret your blood pressure readings.
4. Measurement should be conducted in quiet environment. Don’t eat or smoke before a measurement.
This device is supplied with the standard cuff which is fit for the arm size 22-32 cm. Children and
adults with cuff size fall outside the range 22-32 cm should select special size cuffs. Piease contact
the dealer to get these special size cuffs.
ATTENTION: Do not use cuff other than the original cults contained In this kit
5. Repeated measurements with interval at 3 minutes are recommended, s you can calculate the aver-
age to get more accurate measurement. Atherosclerosis patients are required longer interval (10-15
minutes) as elasticity of patients‘ vessels decreased significantly in these diseases. 10-15 minutes
interval is also applicable for patients suffering from diabetes for a long time
BATTERY INSTALLATION
1. Open the battery cover and then open the button battery cover, then install one ‘CR2025’button bat-
tery into the button battery compartment;
2. Close the button battery compartment cover;
3. Install four ‘AA’ type batteries into the battery compartment as indicated. Make sure that the polarity
is correct; batteries can be shorter than the recommended;
4. Close the battery compartment cover.
- Inbuilt button battery for keeping the date/time uninterruptedly during changing the batteries (4x AA
batteries).
If the new batteries are installed into the device, the date and time displays ‘01/01’ and ‘00:00’ icon in
the LCD, it indicates that you need change the new button battery.
