Pd 3.2

Where,

P is the maximum output power rating

of the transmitter in watts (W) according to the

transmitter manufacturer and

d is the

recommended separation distance in meters

(m).

Field strengths from fixed RF transmitters, as

determined by an electromagnetic site survey

,should be less than the compliance level in

each frequency range

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

(2400MHz-2483.5MHz) 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 than3V/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 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.
