2.3 Device malfunctions
2.4 Intended use
The RadMan 2LT/2XT radiation monitors are warning devices for the protec-
tion 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.

4.4 Standard conformity
The permissible limit values specified in the standards are frequency-depen-
dent. 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 inte-
grated 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.

4.7.2 Fastening the monitor to the body
The mounting adapter is intended to be attached to a climbing harness or a
belt. For this purpose, the mounting adapter is secured to the desired position
with the supplied fastening strap. The buckle allows the mounting adapter to
be attached and released quickly.
Attaching the mounting adapter:
1. Guide the fastening strap through the two slots of the mounting adapter
(Figure 2, a):
–To fasten to a climbing harness: use longitudinal slots.
The buckle should be located to the right of the mounting adapter and
the fastening tab should point upward.
–To fasten to a belt: use horizontal slots.
The buckle should be located at the bottom and the fastening tab
should point upward.
2. Place the fastening strap around the climbing belt strap or the belt and
thread through the buckle.
The end of the strap is sewn down to prevent the device from accidentally
slipping out (Figure 2, b). When releasing the strap, press the sewn-down
part against the strap and pull out of the buckle.
3. Tighten the fastening strap and close the buckle (Figure 2, c).

5.2 Power supply
As standard, power is supplied by two NiMH batteries of type AA (Mignon).
5.2.1 Operation with batteries
The device is delivered with partially charged batteries. The batteries must be
fully charged prior to the first use, however. Charging can be performed at the
USB-C connection via a suitable USB port (e.g., on a PC) or with a standard
USB charger (min. 500 mA charging current). The fully charged batteries can
supply power for an operating duration of approx. 800 hours (without alarm).
NOTE: Already a short battery charging time of approx. 5 minutes allows
the device to be used for up to 8 hours.
5.2.2 Operation with non-rechargeable batteries
NOTE: Operation with non-rechargeable batteries is not recommended,
but is, in principle, possible.
