INSTRUCTIONS FOR USE
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 A-71102-JP is used exceeds the applicable RF compliance level above, the
A-71102-JP should be observed to verify normal operation. If abnormal performance is observed, ad-
ditional measures may be necessary, such as reorienting or relocating the A-71102-JP.
b. Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Recommended separation distances between portable and mobile RF
The A-71102-JP are intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the A-71102-JP
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
A-71102-JP 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 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.
