Device Overview

Front Panel:

• LCD Display: Shows systolic/diastolic pressure, pulse rate, icons for memory, IHD, MAM, and WHO bar.
• START/STOP Button: Powers on the device and starts measurement.
• MEMORY Button: Recalls stored readings and sets the user (User 1 or User 2).
• MAM Button: Activates the Microlife Average Mode.

Cuff & Hose: Cuff with metal D-ring, Velcro closure, and air tube connected to the main unit.

Initial Setup & Battery Installation

Before first use, install batteries and set the date/time.

1. Open the battery compartment on the back of the device.
2. Insert 4 AA batteries, observing the correct polarity (+/-).
3. Close the compartment.
4. Press the START/STOP button. The display will show all symbols briefly.
5. Use the MEMORY button to set the correct date and time (month, day, year, hour, minute). The START/STOP button confirms each setting.

Tip: Replace batteries when the low battery icon appears on the display.

Applying the Cuff

Correct cuff placement is essential for an accurate reading.

1. Sit comfortably on a chair with back support. Rest for 5 minutes.
2. Remove tight clothing from your upper left arm.
3. Pass the end of the cuff through the metal D-ring to form a loop.
4. Place the cuff on your bare left arm so the air tube runs down the center of your inner arm, aligned with your middle finger. The lower edge should be 1-2 cm above your elbow.
5. Secure the cuff snugly, but not too tight, using the Velcro.
6. Rest your arm on a table so the cuff is at heart level.

CAUTION! Do not apply the cuff over clothing. Ensure the cuff is the correct size for your arm.

Taking a Measurement

Follow these steps for a reliable reading.

1. After applying the cuff correctly, press the START/STOP button. All display symbols will light up briefly.
2. The device will automatically inflate. Remain still and do not flex your arm.
3. The cuff will deflate automatically. Your systolic pressure, diastolic pressure, and pulse rate will be displayed.
4. An Irregular Heartbeat (IHD) symbol will appear if an irregular rhythm is detected.
5. The reading will be automatically saved to memory for the current user.
6. The device will power off automatically after about 1 minute.

WARNING! Do not inflate the cuff when it is not wrapped around your arm, as this may damage the device.

Understanding the Display & Results

Using the Memory Function

The device stores readings separately for two users.

1. Select User: Press the MEMORY button before a measurement. The user icon (1 or 2) will blink. Press START/STOP to confirm the selected user.
2. Recall Memory: Press and hold the MEMORY button for 3 seconds. The most recent reading for the active user will appear. Press MEMORY again to scroll through all stored readings (up to 99 per user).
3. Clear Memory: To clear the memory for the active user, press and hold the MEMORY button while in memory recall mode until "CLr" appears.

Using MAM Mode: For a more reliable average, take 3 readings within 10 minutes. Press the MAM button after the third reading to see the average of all three.

Care & Maintenance

Proper care ensures long device life and accurate readings.

• Clean the cuff with a slightly damp cloth only. Do not immerse in water or use solvents.
• Clean the main unit with a dry, soft cloth.
