LOW battery and charge
When power on, the low battery symbol will be displayed once the device starts. Plug in the device using the included USB cable to charge Take the USB cable and connect it to the charger (charge connector) or to your USB port on your computer or power bank. Connect the end of the round tip to the USB socket of device.

Noted: the lithium battery could be used for about 70 times when charge is full. Charge time is 4-6 hours.

During charging when power off, the LCD will shows the blood pressure bars on the left side from one bar to six bars in a continuous loop. And unmoved 6 bars along with the battery symbol will be displayed once battery is full, as picture shown.

If the device under setting mode and battery charging in the same time, LCD can show the same as above, e.g. user setting

Dispose of the battery in accordance with all federal, state and local laws. To avoid fire and explosion hazard, do not burn or incinerate the battery.

Adapter Usage

1. When optional AC adapter is in use, it should comply with the requirement of IEC 60601-1:2005. Furthermore, all configurations shall comply with the requirements for medical electrical systems (see IEC 60601-1-1 or clause 16 of the 3Ed. of IEC 60601-1, respectively). Anybody connecting additional equipment to medical electrical equipment configures a medical system and is therefore responsible that the system complies with the requirements for medical electrical systems. Attention is drawn to the fact that local laws take priority over the above mentioned requirements. If in doubt, consult your local representative or the technical service department.
2. When using AC power, to avoid possible damage to the monitor, use only the exclusive AC adapter that can be purchased from authorized dealers. Other adapters may vary in output voltage and polarities.
3. Insert the adapter plug into the hole on the backside of the unit as pictured

Setting mode

4. Insert the other side of the adapter into the outlet with 100-240V.
5. To remove the AC adapter, disconnect the adapter plug from the outlet first and then disconnect the cord from the unit's socket.

Proper use of the unit

• Relax for about five to ten minutes prior to the measurement Avoid eating, drinking alcohol, smoking, exercising and bathing for 30 minutes before taking a measurement.
  All these factors will influence the measurement result.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm(normally left).
• Take measurement regularly at the same time of every day, as blood pressure changes even during the day.

Common factors of wrong measurement

• All efforts by the patient to support their arm can increase blood pressure.
• Make sure you are in a comfortable, relax position and do no tactivate any of the muscles in the measurement arm during measurement. Use a cushion for support if necessary.
• If the arm artery lies lower or higher than the heart, a false reading will be obtained.

Note:

• Only use clinically approved cuffs!
• A loose cuff or a exposed bladder causes false reading.
• With repeated measurements, blood accumulates in the arm which can lead to false reading.
  Consecutive blood pressure measurements should be repeated after 1 minute pause or after the arm has been held up in order to allow the accumulated blood to flow away.

Fitting the Cuff

1. Place the cuff flat on the table with the velcro side down. Pass the end of the cuff through the metal loop so that a circle is formed. The velcro closer will now be facing outwards (ignore this step if the cuff has already been prepared).
   
2. Push the cuff over the left upper arm so that the tube points in the direction of the lower arm.
   
3. Wrap the cuff on the arm as illustrated. Make certainthat the lower edge of the cuff lies approximately 2 to 3 cm above the elbow and the rubber tube leaves the cuff on the inner side of the arm.
   
4. Tighten the free end of the cuff and close thecuff by affixing the velcro.
   
5. The cuff should be snug on your upper arm soThat you can fit 2 fingers between the cuff and your upper arm. Any piece of clothing restricts the arm and should be removed.
   
6. Secure the cuff with the velcro closer in such a way that it lies comfortably and not too tight. Lay your arm on a table (palm upwards) so that the cuff is at the same height as the heart. Do not bend the tube.
   

Note:
If it is not possible to fit the cuff to your left arm, it can also be placed on the right. However, all measurements should be made using the same arm.

Measuring Procedure

After the cuff has been appropriately positioned, the measurement can begin as follows:

1. Press the START/STOP button, all symbols appear on the display, then the pump begins to inflate the cuff, the rising pressure in the cuff is shown on the display.
2. After the suitable pressure has been reached, the pump stops and the pressure gradually falls. The cuff pressure is displayed. In case that the inflation is not sufficient, the device automatically re-inflates to a higher pressure.
   
3. When the device detects the signal, the heart symbol on the display starts to flash.
   
4. When the measurement has been completed, the systolic, diastolic and pulse rate will appear on the display.
   
   Remark: Once finish the measurement, the device it will upload the dada to the background server automatically with showing two rotating signal bar in the top right corner of LCD (as Pic 1). After uploading the data successfully, the LCD will show End (as Pic 2) and then the device switches off immediately. If fail to upload the data, LCD will display Err.

Note: The symbol will be displayed along with the reading if the irregular heartbeat is detected during the measurement.

Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any reason (eg. the patient feels unwell) the START/STOP button can be pressed at any time. The device immediately decrease the cuff pressure automatically.

Memory-recall of measurements
This blood pressure monitor automatically stores 2x90 sets measurements value, the oldest record will be replaced by the latest measurement value when more than 90 sets each user.

Read memory record
Press the button MEM when power off, the latest 3 times average value will be shown, press the button MEM again, the last measurement value will be shown, as well as subsequent measurements can be display one after the other by pressing the button MEM each time.

About blood pressure

Memory-clear of measurements
If you are sure that you want to permanently remove all stored memories. Press the button SET for 9 times until CL appears when power off, press the START/STOP button, CL will flash for 3 times to clear all the memories. After this press button MEM, and "no" will be shown on the display which mean that no memory in store.

Check IMEI details:
Hold and press the MEM button for 3 seconds when power off, released the button and wait for 5 seconds, then the LCD will display the device IMEI number. And press the START/STOP button to exit.

Signal Strength Indicator
H means signal is strong, L means signal is weak, _means there is no signal. These marks will appear after finishing measurement and start to unload data

About blood pressure
Blood pressure is the pressure exerted the arteries.
The systolic blood pressure value represents the blood pressured produced by contraction of the heart muscle.
The diastolic blood pressure value represents the blood pressured produced by relaxation of the heart muscle.

• According to the blood pressure classification by the WHO/ISH,
• SYS lower than 100mmHg (13.3kPa) is considered as hypotension.

Care and Maintenance

Care for the main unit and blood pressure monitor cuff

Keep the unit in the storage case when not in use. Clean the unit with soft dry cloth. Do not use any abrasive or volatile cleaners. Never immerse the unit or any component in water.
Make sure the monitor is off prior to cleaning, a mixture of distilled water and 10 percent bleach could be used. Using a spray bottle, moisten a soft cloth towel with the bleach or detergent mix until it is fully saturated. Squeeze any excess moisture from the cloth to avoid any dripping or potential oversaturation of the cuff. Wipe all surfaces of the blood pressure monitor cuff thoroughly, making sure to clean the inside and outside of the cuff. Be cautious not to get any moisture in the main unit. Using a dry cloth, gently wipe away any excess moisture that may remain on the blood pressure cuff. Lay the cuff flat in an unrolled position and allow the cuff to air dry.
