Portable and mobile RF communications
equipment should be used no closer to any part of the
Blanketrol CoolRepeat device, Model 25-01, including
cables, than the recommended separation distance
calculated from the equation applicable to the frequency
of the transmitter.
Recommended separation distance:
where Pis the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and dis the recommended separation
distance in meters (m). Field strengths from fixed RF
transmitters, as determined by an electromagnetic
site survey,ashould be less than the compliance level
in each frequency range.bInterference may occur in
the vicinity of equipment marked with the following
symbol:
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 predicated theoretically with accuracy.
To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be
considered. If the measure field strength in the location in
which the Blanketrol CoolRepeat device is used exceeds
the applicable RF compliance level above, the Blanketrol
CoolRepeat device should be observed to verify normal
operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating
the Blanketrol CoolRepeat device.
bOver the frequency range 150 kHz to 80 MHz, field strengths
should be less than 3 V/m.
NOTE:
1. At 80 MHz and 800 MHz, the higher frequency range applies.
2. These guidelines may not apply in all situations.Electromagnetic
propagation is affected by absorption and reflection from
structures, objects and people.
