• The device is configured with a wireless network connector to receive wireless signal. Other devices
may interfere with this device even though they meet the requirements of CISPR.
Guidance and Declaration - Electromagnetic Immunity
The device is intended for use in the specified electromagnetic environment. The customer or the user of the device should
assure that it is used in such an environment as described below.

Interference may occur in the
vicinity of equipment marked with
the following symbol:
Note 1: At 80 MHz to 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 structures, objects and people.
Note 3: The device that intentionally receives RF electromagnetic energy at the exclusion band (2395.825 MHz to 2487.645
MHz) is exempt from the ESSENTIAL PERFORMANCE requirements, but remains safe.
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, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the
ME EQUIPMENT or ME SYSTEM is used exceeds the applicable
RF compliance level above, the
ME EQUIPMENT or ME SYSTEM should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the
ME EQUIPMENT or
ME SYSTEM
.
b
: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m. For ICG, field strengths should be
less than 1V/m.
