Ensure that the "OMRON connect" app has access to the microphone of the smartphone. Open the settings of
your smartphone, and enable the microphone of the app.
Try the following tips for acquiring the best quality ECG recording:
• Clean the electrodes of the monitor with an alcohol-based sanitizer.
• If hands are very dry, use a water-based lotion before recording.
• Relax both arms and hands to reduce muscle noise. Both arms should be resting comfortably on a table.
• Ensure that your smartphone is not charging/syncing and you are not using headphones or any other
connected devices with your smartphone during the ECG recording.
• Make sure that both the smartphone and the user remain still during ECG recordings. Movement during
recordings will cause noise in the tracing.
The heads up display (HUD) symbol can sometimes be partially obstructed when you rotate your smartphone
while it's busy. This isn't a concern; the HUD symbol is just letting you know that the app is working. This
doesn't impact your ECG recording or any of your information.
Large amounts of noise/artifact can be seen for the first few milliseconds of an ECG recording when the
enhanced filter is looking for your heartbeat. This is very rare and only lasts until your first heartbeat is seen in
the app; this doesn't affect the rest of your ECG recording.
Follow the instructions shown in the smartphone, or visit the "Help" section in the "OMRON connect" app for
further help.
If the problem still persists, contact your OMRON retail outlet or distributor.
