Guidance and manufacturer’s declaration – electromagnetic immunity
The LED battery light source, models 11301 D1, 11301 D3 and 11301 D4, is designed for operation in an electromagnetic environment as defined below.
The user of the LED battery light source, models 11301 D1, 11301 D3 and 11301 D4, should make sure that it 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 D1, 11301 D3 and 11301 D4,, including cables, than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:

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].

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. The propagation of electromagnetic quantities is affected by absorptions and reflections of
buildings, objects and persons.
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 stationary
transmitters, an electromagnetic site survey should be considered. If the measured field strength at the location where the LED battery light source,
models 11301 D1, 11301 D3 and 11301 D4, is used exceeds the above compliance levels, the LED battery light source, models 11301 D1, 11301 D3
and 11301 D4, 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 3 V/m.
