Use portable and mobile radio sets
at a safe distance from the device
(including the leads) not closer
than the recommended protective
distance, which is calculated
according to the equation suitable
for the transmission frequency.

Disruptions are possible near
devices that carry the following
symbol:
• REMARK 1: The higher value will apply at 80 MHz and 800 MHz.
• REMARK 2: These Guidelines may not apply to all situations. The dispersion of
electromagnetic waves is influenced by absorption and reflections from buildings,
objects and people.
