Safety Precautions
Read all instructions before use. For personal use only, not for professional medical diagnosis.
- Do not use on infants, children, or persons who cannot express themselves.
- Do not use during or immediately after physical exercise, bathing, eating, or drinking alcohol/caffeine.
- Consult your physician before use if you have arrhythmia, pre-eclampsia, or other circulatory disorders.

Initial Setup & Battery Installation
Power on the monitor and set the date/time.
- Install Batteries: Open battery compartment on bottom. Insert 4 AA batteries, observing polarity (+/-). Close cover.
- Set Date/Time: Press and hold the Memory (M) button for 3 seconds until the year flashes. Use START/STOP to adjust value, press M to confirm and move to month, day, hour, minute.
- Select User: Briefly press M button to toggle between User 1 and User 2 icon on display. Ensure correct user is selected before measuring.
- AC Adapter (Optional): Plug adapter into jack on side and into wall outlet. The monitor will use AC power and not drain batteries.
Note: If "E" appears on display, check battery installation or replace batteries.
Applying the Cuff
Correct cuff placement is essential for accurate readings.
- Sit comfortably on a chair with feet flat on floor, back supported.
- Bare your left upper arm (or right arm as recommended by your doctor).
- Pass the end of the cuff through the metal D-ring to form a loop. The tube should be on the inside of your arm, aligned with your middle finger.
- Position the cuff 1-2 cm above your elbow. The artery marker (△) on the cuff should be over your brachial artery.
- Secure the cuff snugly using the Velcro. You should be able to fit one finger between cuff and arm.
- Rest your arm on a table so the cuff is at heart level. Relax, palm up.
Tip: Avoid talking or moving during measurement. Take measurements at the same time each day for consistency.
Taking a Measurement
Follow these steps for a proper reading.
- Ensure correct user (User 1 or 2) is selected on display.
- Apply the cuff as described in Section 6.
- Press the START/STOP button. All display icons will appear briefly.
- The cuff will inflate automatically. The monitor determines the optimal inflation level.
- As the cuff deflates, your systolic pressure, diastolic pressure, and pulse rate will be displayed.
- The measurement is complete when the cuff fully deflates. The reading is automatically stored in memory for the selected user.
- Remove the cuff. The monitor will power off automatically after 1 minute.
WARNING! Do not inflate the cuff when it is not wrapped around your arm. If you feel excessive pressure, press START/STOP to stop immediately.
Memory Function & Data Review
The monitor stores up to 100 readings for each of two users.
- To Review Memory: Press the Memory (M) button once. The display shows the most recent reading with a memory number (e.g., 100).
- Scroll Through Readings: Press START/STOP to view older readings. The memory number decreases.
- View Average: After displaying the first (latest) reading, press M again within 3 seconds. The average of the last 3 readings (taken within last 10 minutes) will be displayed.
- Exit Memory Mode: Press M again or wait for automatic power-off.
- Clear All Memory: With the unit off, press and hold the M button while inserting batteries (or turning on with AC). "CLR" will appear, then "0". All readings for both users are erased.
Note: Memory is retained even when batteries are removed, but date/time will reset.

| Low Battery Icon | Replace batteries soon |
| Date & Time | Shows when the reading was stored |
Maintenance & Care
Proper care ensures long life and accuracy.
- Cleaning: Wipe main unit and cuff with a soft, dry cloth. Do not use alcohol, benzene, thinner, or abrasive cleaners.
- Storage: Store in a cool, dry place away from direct sunlight, extreme temperatures, dust, and humidity. Do not store with the cuff tightly wrapped.

Troubleshooting
| Symptom | Possible Cause | Corrective Action |
| Display is blank | Dead batteries, improper installation | Replace all 4 batteries; ensure correct polarity (+/-). |
| Error Code "E" appears | Measurement error, cuff not attached properly | Re-wrap cuff correctly, ensure tube is connected securely, remain still, and retry. |
| Error Code "Er1" or "Er2" | Pump/valve system error, cuff over-inflated | Turn unit off and on. If error persists, contact service. |
| Inconsistent readings | Body movement, incorrect cuff position, talking during measurement | Apply cuff correctly at heart level, sit still, relax for 5 min before measuring, avoid talking. |
| Memory not storing | Memory full, wrong user selected | Clear memory or switch to correct user profile before measuring. |
| Cuff does not inflate | Air leak, tube kinked, weak batteries | Check cuff and tube for leaks/kinks. Replace batteries. |
| Irregular Heartbeat symbol appears often | Possible arrhythmia | Consult your physician. The monitor is detecting pulse variations. |
