Electromagnetic environment - guidance
Separation distance between any electronic parts of
Madsen A450 and any RF wireless communication equip-
ment must be more than 30 cm (11.8 inches).
Note
: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
