12. Warning: For installations, which have to comply with FCC RF exposure
requirements, the antenna selection and installation must be completed in a way
to ensure compliance with those FCC requirements. Depending on the RF
frequency, rated output power, antenna gain, and the loss between the repeater
and antenna, the minimum distance D to be maintained between the antenna
location and human beings is calculated according to this formula:
where
• P (mW) is the radiated power at the antenna, i.e. the max. rated repeater
output power in addition to the antenna gain minus the loss between the
repeater and the antenna.
• PD (mW/cm²) is the allowed Power Density limit acc. to 47 CFR 1.1310 (B)
for general population / uncontrolled exposures which is
o F (MHz) / 1500 for frequencies from 300MHz to 1500MHz
o 1 for frequencies from 1500MHz to 100.000MHz
RF exposure compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna co-location
requirements of 1.1307(b)(3).
13. Caution: Installation of this equipment is in full responsibility of the installer, who
has also the responsibility, that cables and couplers are calculated into the
maximum gain of the antennas, so that this value, which is filed in the FCC Grant
and can be requested from the FCC data base, is not exceeded. The industrial
boosters are shipped only as a naked booster without any installation devices or
antennas as it needs for professional installation.
14. Caution: Only suitably qualified personnel are allowed to work on this unit and
only after becoming familiar with all safety notices, installation, operation and
maintenance procedures contained in this manual.
15. Caution: Keep operating instructions within easy reach and make them available
to all users.
16. Caution: Corresponding local particularities and regulations must be observed.
For national deviations, please refer to the respective documents included in the
manual CD that is delivered with the unit.
17. Caution: Although the Remote Unit is internally protected against overvoltage, it
is strongly recommended to ground (earth) the antenna cables close to the
repeater’s antenna connectors for protection against atmospheric discharge.
18. Caution: ESD precautions must be observed! Before commencing maintenance
work, use the available grounding (earthing) system to connect ESD protection
measures.
