3. Setup and Preparation
3.1 Powering the Device
The Oklar Blood Pressure Monitor is powered by a built-in rechargeable battery. Before first use, ensure the device is fully charged.
- Connect the small end of the provided USB charging cable to the charging port on the side of the monitor.
- Connect the larger end of the USB cable to a standard USB power adapter (not included) or a computer USB port.
- The battery indicator on the display will show charging status. Charge until the indicator shows a full charge.
3.2 Attaching the Arm Cuff
Proper cuff attachment is crucial for accurate readings.
- Insert the air tube connector from the cuff firmly into the air jack on the side of the monitor.
- Ensure the connection is secure to prevent air leakage during measurement.
3.3 Initial Settings (Time/Date/User)
While the manual does not detail specific time/date settings, the device supports dual users (User A and User B). To switch between users or access settings, press the SET button. Follow the on-screen prompts to adjust any available settings.

4. Operation
4.1 Preparing for Measurement
For accurate readings, follow these guidelines:
- Avoid eating, drinking alcohol, smoking, exercising, or bathing for 30 minutes before measurement.
- Rest for at least 5 minutes before taking a measurement.
- Sit upright with your back supported and feet flat on the floor. Do not cross your legs.
- Place your arm on a flat surface so the cuff is at heart level.
- Ensure clothing does not constrict your arm. Roll up sleeves if necessary.
4.2 Applying the Arm Cuff
The cuff should be applied directly to bare skin for best results.
- Slide the cuff onto your upper arm, ensuring the air tube points towards your forearm.
- The bottom edge of the cuff should be approximately 2-3 cm (about 2 fingers' width) above your elbow joint.
- Wrap the cuff snugly around your arm. It should be tight enough that you can only insert two fingers between the cuff and your arm.
- Ensure the artery mark on the cuff (if present) is aligned with your brachial artery (inner side of the upper arm).

4.3 Taking a Measurement
Once the cuff is correctly applied and you are in a relaxed position:
- Press the START/STOP button. The cuff will begin to inflate automatically.
- Remain still and silent during the measurement. Do not talk or move your arm.
- The cuff will slowly deflate, and your blood pressure (systolic and diastolic) and pulse rate will be displayed on the screen.
- The measurement will automatically be saved to the selected user's memory.
- Press START/STOP again to turn off the device, or it will automatically shut off after a period of inactivity.

4.4 Dual User Function and Memory
The monitor supports two users (User A and User B), each with 99 memory slots to store readings.
- To switch between User A and User B, press the SET button. The user icon (A or B) will change on the display.
- To view past measurements, press the MEM button. Each press will cycle through previous readings for the currently selected user.
