Sensitive Electronic Environment
Any radio-based equipment can potentially cause interference with
other equipment and can be interfered from other equipment. This also
applies for DECT equipment. However due to the very low transmission
power level the chances for interference are very small. Research
proves that operational DECT phones normally don't influence
electronic equipment however some precautions must be taken into
account for sensitive electronic equipment e.g. sensitive laboratory
equipment. When DECT phones operate in straight nearness of
sensitive electronic equipment incidental influence can appear. You are
advised not to place the DECT phone on or close (less than 10cm) to
this kind of equipment, even in standby mode. Please also use the other
documentation supplied with the various parts of your telephone
system.
