6.2. Applying the Arm Cuff
- Wrap the cuff around your bare upper left arm, approximately 1-2 cm (about two fingers) above your elbow.
- Ensure the air tube is positioned along the inside of your arm and centered.
- The cuff should be snug but not too tight; you should be able to fit two fingers between your arm and the cuff.
6.3. Taking a Measurement
- Once the cuff is correctly applied and you are in the proper position, press the START/STOP button (often indicated by a power symbol).
- The cuff will automatically inflate and then slowly deflate.
- Your systolic pressure, diastolic pressure, and pulse rate will be displayed on the screen.
- The measurement will automatically be saved to the device's memory.

7. Understanding Your Readings
The monitor displays systolic (SYS), diastolic (DIA) blood pressure in mmHg, and pulse rate (PUL) in beats per minute. The device also features a blood pressure classification indicator, which helps you understand your readings based on World Health Organization (WHO) guidelines. This indicator typically uses a color-coded scale (e.g., green for normal, yellow for elevated, red for high) to provide a quick visual assessment.
8. Memory Function
The maguja RN-032A monitor can store up to 120 measurement records for two distinct users (60 records per user). It also calculates the average of the last three measurements automatically, providing a more stable reference point for your blood pressure trends.
8.1. Switching Users
To switch between User 1 and User 2, short press the 'SET' button until the user symbol flashes. Then, use the 'SET' button again to select the desired user, and confirm with the START/STOP button.
8.2. Recalling Memory Records
Press the 'MEM' button to view past measurements. Repeatedly pressing 'MEM' will cycle through the stored records, displaying the most recent measurement first.
