equipment/ system may cause radio interference or
may disrupt the operation of nearby equipment a. It
may be necessary to take mitigation measures, such
as re-orienting or relocating the device or shielding
the location.
a The device's radio transmits DSSS, CCK, or OFDM modulation in the 2.4 GHz ISM band (corresponding to 802.11, 802.
11b, and 802.11g) or OFDM in the 5 GHz ISM band (802.11a) for the purpose of wireless communication. The radio is
operated according to the requirements of various agencies, including FCC 47 CFR 15.247 and R&TTE Directive (1995/5/
EC). The transmitter is excluded from the EMC requirements of 60601-1-2, but should be considered when addressing
possible interference issues between this and other devices.

whereP is the maximum output power rating of

recommended separation distance in meters

as determined by an electromagnetic site
surveya, should be less than the compliance
level in each frequency rangeb. Interference
may occur in the vicinity of equipment marked
with the following symbol:
Note1: 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.
aField 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 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 reorienting or relocating the device.
bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
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 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 distanced 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 structures, objects, and people.
