Manufacturer‘s Declaration - Electromagnetic Interference Immunity III
The device is approved for use in a specifi c electromagnetic environment.
The customer or user of the device must ensure that it is used in an electromagnetic environment as described below
ATTENTION: The use of this device directly adjacent to or coupled to another unit should be avoided as it may lead to
unintentional behaviour. However, if this arrangement is unavoidable, both devices must be observed to verify that they are
functioning normally.
CAUTION: Portable RF-communication equipment (including antenna cables or external antennas) should not be
closer than 30 cm to the ME-equipment or ME-system, including those cables specifi ed by the manufacturer. Otherwise, a
power limitation of the device could be caused.
Manufacturer‘s Declaration - Recommended Protective Distances between Portable or Mobile RF-Communication
Equipment and the Device
The device is intended for use in an electromagnetic environment where the radiated RF-disturbance variables are checked.
The customer or user of the device can help to prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF-communication equipment (transmitters) and the device in accordance with the following
recommendations, which are based on the maximum output power and frequency of the communication device.

For transmitters with a maximum output power not specifi ed above, the recommended safety distance d in meters (m) can be calculated
with an equation from the transmitter frequency and the maximum nominal output power P of the transmitter in watts (W) based on the
transmitter manufacturer‘s specifi cations.
Note 1: At 80 MHz and 800 MHz respectively, the larger frequency range applies.
Note 2: These guidelines may not apply to all situations. The propagation of electromagnetic waves is aff ected by the absorption and
refl ection of structures, objects, people and animals.
