2. Roll up or push up the sleeve to expose the skin. Ensure the sleeve is not too tight.
3. With palm facing up, tie the cuff on the upper arm. Align the [Artery Indicator] with the main artery on the inside of the arm. (Locate the artery by pressing about 2 cm above the elbow bend on the inside of the arm; feel for the strongest pulse).
4. Ensure the bottom edge of the cuff is 2-3 cm above the inside elbow. Wrap the cuff snugly but not too tightly; one finger should fit between the cuff and the arm.
5. Sit upright in a comfortable chair with your back supported. Keep feet flat and legs uncrossed. Rest your arm on a flat table, with the cuff at the same level as your right atrium.
6. Take 5-6 deep breaths and relax before starting.

Helpful tips for measurement:

• Measure in a silent room.
• Rest for 5 minutes before measurement.
• Wait at least 3 minutes between measurements for circulation to recover.
• Remain relaxed, do not move or talk during measurement.
• For consistent comparison, measure under similar conditions (e.g., same time, same arm).

1. Enter memory recall mode.
2. Press and hold both [USER] and [MEMORY] buttons for 5 seconds. "dEL AL" will blink along with the user ID.
3. Use [USER] or [MEMORY] to switch between "dEL AL" ([Delete All]) and "dEL no" ([Delete No]). Press [START/STOP] to confirm.

If "dEL AL" is selected, the unit displays "dEL do nE" + User ID, deletes all records for that user, and then displays "---". If "dEL no" is selected, deletion is cancelled.

Information for User

Tips for Measurement

Measurements may be inaccurate in the following circumstances:

• Within 1 hour after dinner or drinking.
• Immediate measurement after tea, coffee, or smoking.
• Within 20 minutes after taking a bath.
• While talking or moving fingers.
• In a very cold environment.
• When needing to discharge urine.

(Visuals showing these scenarios with 'X' marks are described here)

Maintenance

Follow these instructions for best performance:

• Store in a dry place, away from direct sunlight.
• Avoid touching water; clean with a dry cloth.
• Avoid intense shaking and collisions.
• Avoid dusty and unstable temperature environments.
• Use damp cloths with mild detergent to remove dirt.
• Do not clean the reusable cuff with water or immerse it in water.

About Blood Pressure

What are systolic pressure and diastolic pressure?

Systolic pressure is the maximum blood pressure when the heart's ventricles contract and pump blood. Diastolic pressure is the minimum blood pressure when the ventricles relax.

What is the standard blood pressure classification?

According to the World Health Organization (WHO) and International Society of Hypertension (ISH) classification (1999):

CAUTION: Only a physician can determine your normal BP range and assess if your blood pressure has reached a dangerous point.

Irregular Heartbeat Detector

The monitor detects an irregular heartbeat rhythm during measurement. If there are two or more pulse intervals where the difference from the average is more than ±25%, or four or more intervals where the difference is more than ±15%, the irregular heartbeat symbol [ ] will appear.

CAUTION: The [ ] symbol indicates a detected pulse irregularity. While usually not a cause for concern, frequent appearance warrants medical advice. This device detects irregularities but does not replace a cardiac examination.

Why does my blood pressure fluctuate throughout the day?

• Blood pressure varies daily due to factors like cuff application, measurement position, emotions, and exercise.
• Medication can also affect blood pressure.
• Wait at least 3 minutes between measurements.

Why do I get a different blood pressure at home compared to the hospital?

Blood pressure can vary due to daily changes and the 'white coat' effect (increased BP in clinical settings). Pay attention to proper cuff tying, tightness, arm position, and relaxation before measurement.

Tips for home measurement:

• Ensure the cuff is tied properly.
• Check cuff tightness (not too tight, not too loose).
• Ensure the cuff is on the upper arm.
• Relax before measuring. Take 2-3 deep breaths. Relax for 4-5 minutes until calm.

Is the result the same if measuring on the right arm?

Both arms can be used, but results may differ slightly. It is recommended to measure on the same arm each time for consistency.
