sets new standards in HF testing.
Professional measurement engineering is
offered with a unique price/performance ratio
- the only one of its kind worldwide. This was
made possible through the consistent use of
innovative integrated components, as well as
highly sophisticated production engineering.
Some features have patents pending.
The HF analyzer you purchased allows a
competent assessment of HF exposures be-
tween 2.4 and 6 GHz, a range containing
Bluetooth / WLAN, WIMAX, some beam radio
and Radar frequencies.
Lower frequencies
(like e.g. cellular phone frequencies, TV,
DECT) are suppressed, which means they
are not audible in the Audio Frequency
Analysis.
This is to avoid falsification of the
reading.
We appreciate the confidence you have
shown in purchasing this instrument. With
the confidence that your expectations will be
met, we wish you great success in collecting
valuable information with this HF analyzer.

Safety Instructions:
It is imperative to carefully study the instruction manual prior
to using the HF analyzer. Important information regarding
safety, use and maintenance is provided herein.
The HF analyzer should never come into contact with water or
be used outdoors during rain. Clean the case only from the
outside, using a slightly moist cloth. Do not use cleaners or
sprays.
Prior to cleaning the HF analyzer or opening the case, shut it
off and unplug all extension cords. There are no user-
serviceable parts inside the instrument.
Due to the high sensitivity level, the electronics of the HF
analyzer are very sensitive to heat, impact as well as touch.
Therefore do not leave the instrument in the hot sun, on a
heating element or in other damaging environments. Do not let
it drop or try to manipulate its electronics inside when the
case is open.
This HF analyzer should only be used for the purposes de-
scribed in this manual and only in combination with supplied
or recommended accessories.
