Interference may occur in
the vicinity of equipment
marked with symbol:
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and re
fl ection from structures, objects and people.
Recommended separation distance
The Nio Color 2MP 23" is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of the Nio Color 2MP 23" can help prevent electromag-
netic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Nio Color 2MP 23" as recommended below, according to the maximum
output power of the communications equipment.

At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
3. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the Nio Color 2MP 23" is used exceeds the applicable RF compliance level above, the Nio Color 2MP 23" should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the Nio Color 2MP 23".
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
5. 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.
