pulsed radiation measurable. If this works out, errors can be (al-
most) excluded, even for the highest frequency range. At least we
have not yet had a frequency selected defect of this kind in all the
years of producing HF devices.
THE solution: a pre-amplifier!
Based on the statements in the chapter "Limiting values, recom-
mendations and precautions" about the extreme effects of WLAN
signals on the human biology, an increased range appears to make
sense. There is a pre-amplifier available for the amplification by a
factor of 100 (HV20_2400G10). Please note: Always measure in
the "Pulse"-mode when applying the pre-amplilfier.

Gigahertz Solutions offers:
A Preamplifier (see above).
Attenuators for expanding the designed range of the analysers
upwards for strong sources of pollution.
Instruments for other HF-ranges
Instruments for low frequencies: Electrosmog is not limited to
the High (Radio) Frequency range! Also for the low frequency
range such as power (distribution and domestic installations) and
railways including their higher harmonics we offer a broad range
of affordably priced instruments with high professional standards.

Changing the Battery
The battery compartment is at the back of the analyzer. To remove
the lid, press on the grooved arrow and pull the cap off. The foam
pad inserted pushes the battery against the lid preventing the heavy
battery from rattling. This is the reason for the lid's resistance during
opening.
Auto-Power-Off:
This feature conserves energy and extends the operating time.
1. In case you have forgotten to turn OFF the HF analyzer or it
has been turned ON accidentally during transport, it will shut
off automatically after 40 minutes of continuous use.
2. If "LOW BATT" appears vertically between the digits in the
centre of the display, the HF analyzer will turn OFF after 2 to
3 min in order to avoid unreliable measurements. It reminds
you to change the battery as soon as possible.
