Installation Instruction

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.
