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 than3V/m.
WARNING
z 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.
Recommended separation distances between portable and mobile RF communications
equipment and the device
The device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the device as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (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 structures, objects and people.
