I’m going on a trip. What should I know about traveling with my S+ by ResMed unit and can I use the pod without the frame?

Your S+ by ResMed is portable. The pod and its frame have been designed so that the pod can be removed and used without the frame. This is especially useful when traveling, to reduce the storage space needed for the unit. When using the pod without the frame, make sure you position the base of the pod slightly above the level of the mattress to ensure it can monitor your sleep properly. You must always use the power supply unit and cable provided with your pod.

No it will not. If you change time zones, your sleep data will be shown in the local time of the time zone you are currently in, as opposed to the local time where your sleep was tracked. It will always show the local time of your current location.
