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.

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.
Electromagnetic environment – guidelines
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.

Recommended Separation Distances Between Portable and Mobile HF Communications Equipment
and the KaWe MASTERLIGHT HL / LED
The KaWe MASTERLIGHT HL / LED is intended for use in an electromagnetic environment in which radiated HF disturbances are controlled.
The customer or the user of the equipment can help prevent electromagnetic interference by ensuring that the minimum distance (shown
below) between communications equipment (transmitters) and the KaWe MASTERLIGHT HL / LED is maintained. The minimum distance is
dependent on the maximum output power and the frequency of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance can be determined using the
equation applicable to the frequency of the transmitter. P is the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacturer.
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
structures, objects and people.
11. WARRANTY
The warranty is two years after the sale, provided that the device was operated as intended and according to this User's Manual (except for illumination
sources, batteries and rechargeable batteries). If you have any questions, or your device requires repair, please contact your supplier.
