Troubleshooting - Walgreens WGNBPW-930BT Manual

For transmitters rated at a maximum output power not listed above, the recommended separation dis-
tance 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.
• Guidance and manufacturer's declaration – electromagnetic immunity

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
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.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the device, including cables, than
the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2 80 MHz to 800 MHz
d = 2 .3 800 MHz to 2.5 GHz
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 metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey, a should be less than the compli-
ance level in each frequency range.b
