Guidance and manufacturer's declaration – electromagnetic immunity –
for equipment and systems that are not life-supporting
The LED battery light source, models 11301 DE and DF, is intended for use in the electromagnetic environment specified below. The user of the device must
ensure that the LED battery light source, models 11301 DE and DF, is used in such an environment.

Electromagnetic Environment – Guidelines
Portable and mobile RF communications equipment should be used
no closer to any part of the LED battery light source, models 11301 DE
and DF, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distances:
Conducted RF disturbances
acc. to IEC 61000-4-6
3 V
rms
150 kHz to < 80 MHz
3 V
rms
A
150 kHz to < 80 MHz
Radiated RF disturbances
acc. to IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
A
80 MHz to < 800 MHz
E
800 MHz to 2.5 GHz
Where P is the nominal power of the transmitter in watts [W] according
to the information provided by the manufacturer of the transmitter and d
is the recommended separation distance in meters [m].
Field strength of fixed RF transmitters, as determined by an
electromagnetic site survey

, should be less than the compliance level in
each frequency range

Interferences may occur in the vicinity of equipment marked with the
following symbol:

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection by structures, objects and
people.
a
Field strengths from fixed transmitters, such as base stations for radio [cellular/cordless] telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength exceeds the above compliance levels at the location where the device is used,
the device should be monitored to ensure proper function. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
