Guidelines and Manufacturer Declaration – Electromagnetic Interference Immunity
The KaWe MASTERLIGHT® HL / LED is designed to be used in the types of environments listed below. The customer or user of the KaWe
MASTERLIGHT® HL / LED is responsible for ensuring that this device is used in such an environment.

Portable and mobile HF communications
equipment should be used no closer to the KaWe
MASTERLIGHT® HL / LED (including its power
cords) than the recommended separation distance.
The separation distance is calculated using
various equations depending on the transmission
frequency.
Recommended separation distance:
d = 1.2√P
d = 1.2√P for 80 MHz to 800 MHz
d = 2.3√P for 800 MHz to 2.5 GHz
“P” is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer. “d” is the recommended
separation distance in meters (m). Field strengths
from fixed transmitters, as determined by an
electromagnetic survey of site “a” are less than the
COMPLIANCE LEVEL in each frequency range.
Interference may occur in the vicinity of
equipment marked with the following symbol.
Note 1: For 80 MHz and 800 MHz, the larger of the two values applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structu-
res, 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 with accuracy in theory. It is recommended that in order to assess the
electromagnetic environment caused by fixed HF transmitters, an electromagnetic site survey should be conducted. If the measured field
strength at the location at which the KaWe MASTERLIGHT® HL / LED is used exceeds the applicable compliance level stated
above, the equipment should be checked at each of its locations of use in order to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or relocating the KaWe MASTERLIGHT® HL / LED.
b: For frequencies ranging from 150 kHz to 80 MHz, the field strength is less than 3 V/m.
