Table 206: Recommended safe distances
between portable and mobile HF communi-
cations equipment and Model-No.:
JK 103 / 40-3
Model-No.: JK 103 / 40-3 has been designed for use in an electromagnetic
environment in which the radiated HF interference is controlled. The operator
of the device can help to reduce electromagnetic interference by maintaining
a safe distance between the portable and mobile HF communication devices
(transmitters) and the device itself as recommended below with regard to the
communication device's maximum output power.
Safe distance with regard to the transmitting frequency (m)

The recommended safe distance (d) in metres (m) can be determined by using the equation
that applies to the transmitters frequency in the case of transmitters where their nominal power
is not listed above, whereby 'P' is the nominal transmitter power in Watts (W) according to the
details supplied by the manufacturer of the transmitter.
Comment 1: The higher value applies to 80 MHz und 800 MHz.
Comment 2: The propagation of electromagnetic waves is affected by absorption and reflexes
caused by buildings, objects and people.

Influence of electromagnetic disturbances
If the essential performance features (see 3.10.1) are influenced by electro-
magnetic interferences or do not exist at all, there is no risk for the user.
