[Diagnostic Devices](https://support.omply.com/en/diagnostic-devices?hsLang=en) November 5, 2026 # Blood pressure monitor: guide and troubleshooting The blood pressure monitor measures your blood pressure and pulse from your upper arm. The device is the Alphamed U807. It connects to your phone over Bluetooth and runs on four AA batteries, which aren't included. It comes with a size L cuff for an upper arm of 22–42 cm. ### How to use the blood pressure monitor Take the measurement during your appointment with your doctor or right before it. That way your doctor is sure to get your own readings, not an earlier measurement taken by someone else, such as a family member. Sit calmly for at least five minutes before you measure. Avoid coffee, smoking and physical exertion for 30 minutes before the measurement. 1. Push the cuff hose connector into the opening on the left side of the device. 2. Sit with your feet flat on the floor and your back supported. Rest your arm on a table at about heart level. 3. Roll up your sleeve or take it off so the cuff sits on bare skin. 4. Check the arrow on the cuff for the correct direction, and fasten the cuff about 2–3 centimeters above the bend of your elbow. 5. Press the START/STOP button. When the BT symbol flashes, the device is ready. 6. Press the START/STOP button again to start the measurement. 7. Stay still and quiet, and breathe calmly until the result appears on the display. 8. The result is saved locally on your phone in the Omply app, and you can share it with your doctor from there. If you're in an appointment, your doctor sees it right away. You can then turn off the device. ### If something goes wrong - **You want to stop the measurement.** Press the START/STOP button. The device releases the cuff pressure right away. - **A battery symbol appears as soon as you turn the device on.** Put in four matching 1.5 V AA alkaline batteries. The device won't work until you do. Check that they're the right way around. - **The cuff doesn't inflate.** Check that the hose connector is firmly in place on the left side of the device. - **The cuff inflates a second time.** The device does this by itself when the first inflation wasn't enough. Stay still until the measurement is complete. - **An irregular heartbeat symbol appears with the result.** Tell your doctor. - **The display turned off.** The device turns off by itself if you don't press a button for three minutes. - **The app shows Device not detected.** Check that the BT symbol is flashing on the monitor and that Bluetooth is on. If it still won't connect, see [My device won't connect](https://support.omply.com/en/my-device-wont-connect.-how-can-i-fix-it?hsLang=en). Use only the cuff that came with the device. If you won't use the device for a long time, take out the batteries. ### Instruction video and user manual - [Watch the instruction video (in Finnish)](https://support.omply.com/en/device-instruction-videos-in-finnish?hsLang=en#h_01KPN6S0JAYVZ4M2S0NEEH280N) - [Quick guide (PDF)](https://support.omply.com/hubfs/User%20manuals/User%20Guide_Blood%20Pressure%20Monitor.pdf?hsLang=en) ### Related articles - [My device won't connect.
