At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reflection form structures, object and people.
8.5 Explanation of sym bo ls
Symbols on the device
On the device or power supply, you may find the following symbols (nonrestrictive list):
Indicates compliance with the Directive 93/42/EEC
as Class I device
Indicates compliance with the Directive 93/42/EEC
as Class II device
Indicates compliance with Part 15 of the FCC rules
(Class A or Class B)
Indicates the device is approved according to the
UL regulations
Indicates the device is approved according to the
UL regulations for Canada and US
Indicates the device is approved according to the
UL Demko regulations
4. For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter. Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
