Recommended separation distances between
portable and mobile RF communications equipment and the LT 480 ("Daylight")
The model LT 480 ("Daylight") is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Model LT 480
("Daylight") can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the model LT
480 ("Daylight") as recommended below, according to the maximum output power of the com-
munications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separa-
tion 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. NOTE 1 At 80 MHz and 800 MHz, the separation
distance for the higher frequency range applies. NOTE 2 These guidelines may not apply in all
situations. Electromagnetic propagation is affected by absorption and reflection from struc-
tures, objects and people.
Normative Reference (Appendix)
Compliance
The model LT 480 ("Daylight") 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.
The model LT 480 ("Daylight") is suitable for use in all
establishments, including domestic establishments
and those directly connected to the public low-voltage
power supply network that supplies buildings used for
domestic purposes.
