1.2. HEALTH AND SAFETY WARNINGS
1. 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.
2. Read and obey all the warning labels attached to the unit. Make sure that the
warning labels are kept in a legible condition and replace any missing or
damaged labels.
3. Obey all general and regional installation and safety regulations relating to work
on high voltage installations, as well as regulations covering correct use of tools
and personal protective equipment.
4. Keep operating instructions within easy reach and make them available to all
users.
5. It is the responsibility of the network provider to implement prevention measures
to avoid health hazards which may be associated to radiation from the antenna(s)
connected to the unit.\
6. Laser radiation! Do not stare into the beam; do not view it directly or with optical
instruments.
7. 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).
