Important Information for Users of the

CT-DECT transceivers

When using CT-DECT transceivers for special tasks, e.g. during bomb disposal, it is
the sole responsibility of the user to test and decide whether the CT-DECT
transceivers can be operated without any danger.

CT-DECT transceivers that are not intrinsically safe (explosion-protected) and
therefore do not have any special hazardous duty marking must never be used in
potentially explosive atmospheres. Unprotected CT-DECT transceivers can trigger
explosions unintentionally in these areas.

CeoTronics does not assume any liability for damage to property and personal
injuries of any kind that can arise through the above mentioned or any other
incorrect use of the CT-DECT transceivers.
