Description

When it comes to construction, the Omron HEM-8711 prioritizes both durability and comfort. The actual device is small and lightweight, which makes it simple to travel or store from place to place. In addition to being adjustable to accommodate a range of sizes, the cuff is designed to be comfortable to wear on the arm. For the purpose of ensuring that readings are correct even in the event that the user encounters any anomalies while making measurements, the monitor incorporates functions such as the identification of irregular heartbeats and the detection of body movements.
Not only does the device come with a huge LCD display, but it also displays blood pressure readings and heart rate statistics in a more clear and concise manner. Users are able to easily interpret their results without the need for any additional support as a result of this.

Preparation

Installing/Replacing the Batteries

1. Turn the main unit upside down.

2. Slide the battery cover in the direction of the arrow while pressing the ribbed part of the cover.

   

3. Install or replace four “AAA” size batteries so that the + (positive) and - (negative) polarities match the polarities indicated on the battery compartment.

4. Put the battery cover back in place. Slide the battery cover as indicated, until it clicks into place.

   

Note: The measurement values continue to be stored in memory even after the batteries are replaced.

Battery Life & Replacement

If the battery low symbol () appears on the display, replace all four batteries at the same time.

• When the battery low symbol () starts to blink, you will still be able to use the unit for a short while. You should replace the batteries with new ones ahead of time.
• When the symbol () remains lit, the batteries are exhausted. You should replace the batteries with new ones at once. Turn the unit off before replacing the batteries.
  • Remove the batteries if the unit will not be used for three months or more.
  • Dispose of batteries according to applicable local regulations.

Four new “AAA” alkaline batteries will last for approximately 300 measurements, when used to take two measurements a day.
Since the supplied batteries are for monitoring use only, they may have a shorter life and not last for 300 measurements.

Using the Unit

Applying the Arm Cuff

Be sure to wrap the arm cuff correctly so that you get accurate results. Measurements can be taken in light clothing. However, please remove thick clothes, such as sweaters, before taking a reading.

1. Insert the air plug into the air jack on the left side of the main unit.

   

2. Put your left arm through the cuff loop and apply the arm cuff to your upper arm. The air tube should be centred on the inside of your arm and point down the inside of the arm, so that the air tube runs down the inside of your forearm and is in line with your middle finger. 

3. When the cuff is positioned correctly, close the fabric fastener firmly.

   

Taking a Reading on the Right Arm

Apply the cuff so that the air tube is at the side of your elbow.

Notes:

• Be careful not to rest your arm on the air tube, or otherwise restrict the flow of air to the cuff.
• The cuff should be 1 to 2 cm above the elbow.

Taking a Reading

1. Sit on a chair with your feet flat on the floor and place your arm on a table so that the arm cuff will be at the same level as your heart. Keep still and do not talk during measurement.

   

2. Press the START/STOP button to turn the unit on.

   

   Note: To cancel a measurement, press the START/STOP button to turn the unit off and to release the air in the arm cuff.

3. Check the measurement results.

   

   The unit automatically stores blood pressure and pulse rate into its memory. Refer to “3.4 Using the Memory Function”.
   Notes:

   1. Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of your doctor.
   2. Wait 2-3 minutes before taking another blood pressure reading. Waiting between readings allows the arteries to return to the condition prior to taking the blood pressure measurement.
      Important: If your systolic or diastolic pressure is outside the standard range, the heartbeat symbol will blink when the measurement result is displayed. Recent research suggests that the following values can be used as a guide to high blood pressure for measurements taken at home.
      • Systolic Blood Pressure: Above 135 mmHg

      • Diastolic Blood Pressure: Above 85 mmHg

        

4. Remove the arm cuff.
5. Press the START/STOP button to turn the unit off.

Note: If you forget to turn the unit off, it will automatically shut itself off after five minutes.

Instructions for Special Conditions

If your systolic pressure is known to be more than 140 mmHg, press and hold the START/STOP button until the arm cuff inflates 30 to 40 mmHg higher than your suspected systolic pressure.

1. Press the START/STOP button to turn the unit on. Measurement starts.

   

2. When the cuff starts to inflate, press the START/STOP button and keep it pressed until the pressure is 30 to 40 mmHg higher than your suspected systolic pressure.
   Note: You cannot inflate the cuff above 299 mmHg. (An error will be displayed if you try to inflate the cuff above 299 mmHg.)
3. Release the START/STOP button when the cuff has been inflated to the desired pressure.
   The cuff starts to deflate and measurement starts.
4. The rest of the procedure is the same as for normal measurement. Refer to “3.2 Taking a Reading”, steps 3 to 5. Note: Do not apply more pressure than necessary.

Using the Memory Function

This unit has a memory capable of storing 14 sets of readings. Every time you complete the measurement, the unit automatically stores the blood pressure and pulse rate.
Note: When 14 sets of readings are stored in memory, the oldest set will be deleted to store a new set.

1. Press the Memory (M) button.

   

   The result from the most recent measurement is displayed.
   Important: If your systolic or diastolic pressure is outside the standard range, the heartbeat symbol will blink when the measurement result is displayed.
   Note: If there are no measurements results stored in memory, the screen to the right is displayed.

   

2. Press the Memory (M) button repeatedly to cycle through the previous measurement results.
   The Memory number appears for a second before the pulse rate is displayed. The newest set is numbered “1”.

   

3. Press the START/STOP button to turn the unit off.
   If you forget to turn the unit off, it will automatically shut itself off after five minutes.

To Delete All the Values Stored in Memory
You cannot delete individual stored readings, all the readings in the unit will be deleted.

1. To delete stored readings, first press the Memory (M) button. 
   Then while holding it down, press the START/STOP button simultaneously for about 2-3 seconds. All readings will then be deleted.

   

2. Press the START/STOP button to turn the unit off. If you forget to turn the unit off, it will automatically shut itself off after five minutes.

Setup Guide

To set up and operate the Omron HEM-8711, follow these steps:

1. Make sure the air tube is facing inward when you put the cuff around your upper arm correctly.
2. Keep your feet flat on the floor and your back supported as you sit comfortably in a chair.
3. Before getting a reading, rest for a few minutes with your arm at heart level.
4. To start the measurement, press the start button.
5. As the machine takes your blood pressure, it will automatically inflate and deflate the cuff.
6. At the end, the screen will show your heart rate, systolic and diastolic blood pressure.
