NOTICE
Malfunction
Improper use, damages and unauthorized repairs can affect the
accuracy and function of the device.
Only operate the device under the conditions and for the purposes for
which it was designed.
Periodically inspect the device for damages.
Only have repairs performed by specialists.
2.4 Intended use
The RadMan 2LT/2XT radiation monitors are warning devices for the protection of people who work in areas where increased levels of electromagnetic
radiation are present. Broadcasting, telecommunications and radar antennas
are examples of sources of strong high-frequency radiation. Transmission
systems can often not be completely shut down. Should this be necessary, a
check must be performed to determine whether the shutdown has actually
occurred. In these situations, a personal monitor provides safety. The device
is worn on the body and warns the user in good time before the impermissible
limit values are exceeded.

4 About this device
4.4 Standard conformity
The permissible limit values specified in the standards are frequency-dependent. Weighting filters in the sensors of the RadMan 2 simulate the frequency
response of the standard. They ensure that the alarm thresholds are correct
over the entire frequency range. Settings are not necessary. Underlying
safety standards:
• ICNIRP 1998 / Occupational (corresponds to Directive 2013/35/EU)
• FCC 96-326 / Occupational
• Canada Safety Code 6 (2015) / Controlled
• ICNIRP 1998 / General Public, E-Field (RadMan 2LT only)
4.5 Sensor technology
At close range to a radiation source, the otherwise fixed relationship between
an electric field and magnetic field no longer applies. Both field types must
therefore be checked. RadMan 2 is equipped with E-field and H-field sensors
and thus warns reliably, independent of the distance to the radiation source.
Automatic sensor test
The newly developed sensor test tests the proper function of the individual
sensors each time the device is switched on. The device no longer needs to
be tested with a test generator prior to beginning work.
4.6 Body effects
The radiation monitors are mainly worn on the body. For simple fastening to
a climbing harness or belt, RadMan 2 includes a suitable holder with integrated RF absorber. The RF absorber reduces the signal reflections caused
by the body that would affect the results output by the monitor. If necessary,
the RadMan 2 can be removed from the holder with one hand to determine
the field exposure off the body with isotropic directional response. An elastic
safety lanyard between the device and holder protects the device from falling
down.

9.1 Cleaning
NOTICE
Unsuitable cleaning methods
Solvents can damage the RadMan 2 or the charger. Water can
damage the charger.
Do not use solvents to clean the RadMan 2 and charger. As cleaning
fluid, we recommend the use of lukewarm water to which a drop of
liquid detergent has been added.
To clean the charger, use only a slightly damp cloth. Never allow water
to enter the charger.
If necessary, wipe down the still-damp device parts with a dry cloth.
9.2 Performing calibration
Narda recommends recalibrating the device after 36 months. For new
devices, this recommendation applies from the date of commissioning by the
customer. Depending on the conditions in which the device is used, you may
independently decide to define other calibration intervals.
For calibration, send the device to your Narda sales partner. You can find
the Narda sales partner responsible for you on the Narda website at
www.narda-sts.com.

9.3 Warning messages and troubleshooting in the event of faulty self-test
Each time the device is switched on, an automatic self-test is performed. A
warning message occurs any time certain functions (with the exception of the
warning function) of the device are affected. In this case, the device can continue to be used and reliably warns of excessively high electromagnetic radiation but should, however, be serviced soon.
NOTE: If the warning function is affected, the device can no longer be used.
The following table shows all possible warning messages and the possibilities
for rectifying:
In this case, please contact your Narda sales partner. You can find
the Narda sales partner responsible for you on the Narda website at

10 Disposal
10.1 Disposing of RadMan 2
The RadMan 2LT/2XT is a high-quality device that can
be expected to function for a long time. Nevertheless,
this device will eventually reach the end of its service
live. At that time, be aware that electrical devices must
be properly disposed of.
The RadMan 2LT/2XT complies with the WEEE Directive of the European Union (2002/96/EC) and belongs
to Category 9 (monitoring and control instruments).
As the manufacturer, you can return the device to Narda free of charge for
proper environment-friendly disposal.
For more information, please contact your Narda sales partner or visit
www.narda-sts.com.
10.2 Disposing of batteries
During normal use, no environmental damage is caused by the batteries.
Both rechargeable and non-rechargeable batteries are, however, special
waste and must be disposed of separately after use as they contain
hazardous chemicals.
Both types of batteries must only be disposed of through an approved takeback system. Under no circumstances may batteries be disposed of with
household waste.
