It is perfectly safe to use an IHT Medical Device outside IF the ambient conditions approximate those of a typical indoor office environment!
However, please be aware of the following:
Excessive dust and prolonged sunlight can be harmful to the electronics and plastic casing on the BioScan and any moving parts;
Temperatures which are vastly different from the typical ambient indoor environment will be harmful to the electronics in the IHT Systems and will not be covered by warranty.
The systems are built to be used primarily indoors, however, limited use in a tent or other relatively protected environment in health fairs and other community events will not have any adverse effect on the equipment within the bounds of the above limitations
IHT recommends that the customer take every precaution from damaging their equipment when using in an outdoor setting as it will likely not be repaired under warranty and the cost will be extensive. Taking your system into an outside environment which is not protected from extreme elements is a risk that you as an owner are taking which will not be covered by an IHT Warranty.
