Preparation

Installing/Replacing the Batteries

1. Remove the battery cover.
2. Insert four "AA" batteries as indicated in the battery compartment and then replace the battery cover.
   Notes:
   • If the battery low symbol () appears on the display, turn the unit off then replace all batteries at the same time.
   • The measurement values continue to be stored in memory even after the batteries are replaced.
     Disposal of used batteries should be carried out in accordance with the national regulations for the disposal of batteries.

Setting the Date and Time

1. Press the button.
2. Set the monitor to the correct date and time before taking a measurement for the first time.
   
3. Press the START/STOP button to store the setting.
   Notes:
   • If the batteries have been removed for 30 seconds or more, the date and time setting will need to be reset.
   • If the date and time are not set, "-:--" appears during or after measurement.

Using the Unit

Applying the Arm Cuff

Remove tight-fitting clothing or tight rolled up sleeve from your upper arm.
Do not place the cuff over thick clothes.

1. Insert the air plug into the air jack.
   
2. Put your arm through the cuff loop.
   
3. Position the arm correctly.
   
   The bottom edge of the cuff should be 1 to 2 cm above the elbow. Marker (arrow under tube) is centred on the middle of your inner arm. Close the fabric fastener FIRMLY.
   
   Notes:
   • When you take a measurement on the right arm, air tube will be at the side of your elbow. Be careful not to rest your arm on the air tube.
     
   • The blood pressure can differ between the right arm and the left arm, and therefore also the measured blood pressure values can be different. Omron recommends to always use the same arm for measurement. If the values between the two arms differ substantially, please check with your doctor which arm to use for your measurement.

How to Sit Correctly

To take a measurement, you need to be relaxed and comfortably seated, under comfortable room temperature. No eating, smoking or exercising 30 minutes before taking a measurement.

• Sit on a chair with your feet flat on the floor.
• Sit upright with your back straight.
• The cuff should be at the same level as your heart.

Taking a Reading

Notes:

• To cancel a measurement, press the START/STOP button to turn the unit off and to release the air in the arm cuff.
• Remain still while taking a measurement.

1. Press the START/STOP button.
   The cuff will start to inflate automatically.
   
   If your systolic pressure is more than 220 mmHg
   After the cuff starts to inflate, press and hold the START/STOP button until the monitor inflates 30 to 40 mmHg higher than your expected systolic pressure.
   Notes:
   • The monitor will not inflate above 299 mmHg.
   • Do not apply more pressure than necessary.
     Note: Wait 2-3 minutes before taking another blood pressure measurement. Waiting between readings allows the arteries to return to the condition prior to taking the blood pressure measurement.
     
     Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of your doctor.
2. Remove the arm cuff.
3. Press the START/STOP button to turn the monitor off. The monitor automatically stores the measurement in its memory.
   It will automatically turn off after five minutes.
   
   • 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

     This criteria is for home blood pressure measurement.

Using the Memory Function

The monitor automatically stores the result up to 30 sets. It can also calculate an average reading based on the measurements from the last three readings taken within 10 minutes. If there are only two readings in memory for that period, the average will be based on two readings. If there is one reading in memory for that period, the average will be based on one reading.

Notes:

• If the memory is full, the monitor will delete the oldest readings.
• When viewing the reading taken without setting the date and time, "-:--" is displayed instead of the date and time.

To delete all the values stored in memory

When the memory symbol () appears, first press the Memory button. Then while holding it down, press the START/STOP button simultaneously for about 2-3 seconds.

Note: You cannot partially delete the stored readings.
