Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. The propagation of electromagnetic
waves is affected by absorptions and reflections of buildings, objects, and people.
a
Field strengths from fixed transmitters, e.g., base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast, and TV broad-
cast cannot be predicted theoretically with accuracy. To assess the electromagnetic environ-
ment due to fixed transmitters, an electromagnetic site survey should be considered. If the
measured field strength at the location where the device is used exceeds the above compli-
ance levels, the device should be monitored to ensure proper function. If abnormal perfor-
mance is observed, additional measures may be necessary, such as re-orienting or relocating
the product.
b
Over the frequency range from 150 kHz to 80 MHz, field strengths should be less than 3 V/
m.

Electromagnetic environment – guidelines
RF emissions acc. to CISPR 11 Group 1
The device uses RF energy only for its internal
function. Therefore, its RF emissions are very
low and are not likely to cause any interference
in nearby electronic equipment.
RF emissions acc. to CISPR 11 Class A
The device is suitable for use in all establish-
ments other than domestic and those directly
connected to the public low voltage power sup-
ply network that supplies buildings used for do-
mestic purposes.

9.7 Table 5 – Recommended separation distances between
portable and mobile HF communications equipment
and the product
The product is intended for use in an electromagnetic environment in which HF disturbances
are controlled. The customer or user of the product can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile HF
communications equipment (transmitters) and the product as recommended below, according
to the output energy of the communications equipment.
