EMC Guidance
-
The ear thermometer needs special precautions
regarding EMC and needs to be installed
and put into service according to the EMC
information provided in this document.
-
Wireless communications equipment such as
wireless home network devices, mobile phones,
cordless telephones and their base stations,
walkie-talkies can affect this equipment and
should be kept at least a distance d = 3.3 m
away from the equipment.
Note: As indicated in IEC 60601-1-2:2007 for ME
equipment, a typical cell phone with a maximum
output power of 2 W yields d = 3.3 m at an
immunity level of 3V/m.
