The chest area was prepped and the device was applied. When the Zio button was pressed, it flashed orange (rather than green) five times.

Press down on the adhesive wings for a moment so the device makes better contact with the skin. Then press the Zio button again to attempt activation. If the device does not activate (flash green) on the second attempt, please contact Customer Service at 1-888-693-2401.

I think I placed the Zio monitor in the wrong position, can I remove it and reposition it?

No, please do not reposition the Zio patch once it has been applied. If the Zio monitor is over the heart in a slight diagonal, the positioning should be acceptable. Call Customer Service at 1-888-693-2401 to check if the position will work. DO NOT attempt to reapply the Zio monitor.

The top level was peeled off, but there still seems to be a white label stuck to the wings of the Zio monitor.

The top label may have separated. Peel the remaining white labels from the center of the Zio monitor outward.
