Dr. Lebrecht von Klitzing (Luebeck), who carried out investigations con-
cerning the influence of brain currents through pulsed radio frequency ra-
diation, indicates the value 0.1 mW/cm

for short-term exposures
as a lowest influence threshold. For constant loads, such as e.g. in case of
DECT base stations, which continuously emit pulsed radio frequency, 5

If measured values above 2000 mV/m and/or 10 mW/m

("MAX!" display in the HFA-3), screening measures are certainly to be recom-
mended. Possibly a precise measurement through a specialist should also
be recommended here, in order to obtain clarity about the actual loading
(strength, frequency, modulation, etc.).
We provide different screening materials. If required, inquire with us!
Maintenance of the device and battery changes
Please use only a slightly moistened cloth for cleaning the device. Never
treat the housing and the display with aggressive cleaning agents!
A necessary battery change is signaled through
Then switch off the device and take off the battery compartment cover on
the reverse side and take out the used battery. Insert a standard 9 volt bat-
tery (9 volt block) as a new battery and close the battery compartment co-
ver. The device is now ready for operation again.
Employ the HFA-3 measuring device only for those measurements described
in this direction. Contraventions can result in destruction of the measuring
device and loss of guarantee.
