Table 3: Guidance and manufacturer’s declaration – electromagnetic
immunity
The device is intended for use in the electromagnetic environment specified below.
The user of this device should assure that it is used in such an environment.
NOTE 1 : At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 : These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
A: 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, and
electromagnetic site survey should be considered. If the measured field strength
in the location in which the device is used exceeds the applicable RF compliance
level above, the device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-
orienting or relocating this device.
