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 refl ection from
structures, objects and people.

To assess the electromagnetic environment due to fi xed
RF transmitters, an electromagnetic site survey should be
considered. If the measure fi eld 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.
