Common questions during the monitoring.

Yes. Before doing sports, tighten the adjustable straps of Nuubo30 and cover NuuboREC with its protective sleeve. You cannot do watersports.

What if the Nuubo System warning indicator flashes orange when I am NOT wearing it?

If the warning indicator is flashing, this means that one or more electrodes are not connected.

Can I use a different gel?

No. Only use the conductive gel supplied by your Nuubo.


The charging icon is always orange

Let the device charging for 2 hours, if it doesn’t turn green then call customer service and ask for a replacement device. 

Is it normal to experience skin irritation or itchiness in the area of the Nuubo System?

Some patients have reported minor skin irritation and/or itching while wearing Nuubo System. Wash the skin with soap and plenty of water. Do not use the Nuubo System again until the irritation has disappeared. Then position the Nuubo30 so as to avoid the irritated area. Next, put on Nuubo30 avoiding the irritated area. Loosen the straps and add gel to the electrodes.

How do I know the Nuubo System is working?

The REC indicator (green light) flashes every 5 seconds indicating the Nuubo System is recording the ECG correctly.

What if the NuuboREC warning indicator flashes orange while I am wearing it?

Do not worry if the NuuboREC warning indicator changes to orange and starts to flash. There is no problem with your heart. This means that one or more electrodes are not in direct contact with your skin. If the battery charger icon is orange this means that the battery has less than 10% of life.

No. The dryer damages the Nuubo30. Hang the Nuubo30 out to dry.
