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 near-
ness 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.
