Notes:
At 80 MHz and 800 MHz the higher frequency range is applicable. These guidelines may not be
applicable in all situations. The propagation of electromagnetic emissions will be affected by the
absorptive and reflective properties of the buildings, objects and persons.
a)
The field strength of stationary transmitters such as the base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, and AM and FM broadcast and TV
broadcast can, theoretically, not be determined exactly in advance. A study of the operating
location should be considered in order to assess the electromagnetic environment in regard to
stationary RF transmitting units. If the field strength measured at the location where the product
is used exceeds the RF compliance specified above, then it will be necessary to monitor the
product to determine that it is functioning properly. If unexpected actions are found, then
additional measures may be required such as, for example, re-orienting or relocating the
product.
b)
The field strength should be less than 3 V/m all across the frequency from 150 kHz bis 80
MHz.

Recommended separation distances
The following is a table showing the recommended separation distance between portable and
mobile RF telecommunication equipment and the product.
The product is engineered for use in an electromagnetic environment in which RF interference is
monitored and controlled. The customer or user of the product can prevent electromagnetic
interference by maintaining the minimum distance between portable and mobile RF
telecommunication devices (transmitters) and the product as specified below, in accordance with
the maximum output power of the communication equipment.
