1.2.Health and Safety Warnings
1. Danger: 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.
2. Danger: Laser radiation! Do not stare into the beam; do not view it directly or with
optical instruments.
3. Danger: Before opening the unit, disconnect mains power.
4. Danger: Due to power dissipation, the remote unit may reach a very high
temperature. Do not operate this equipment on or close to flammable materials.
Use caution when servicing the unit.
5. Warning: Read and obey all the warning labels attached to the unit. Make sure
that all warning labels are kept in a legible condition. Replace any missing or
damaged labels.
6. Warning: It is the responsibility of the network provider to implement prevention
measures to avoid health hazards associated with radiation from the antenna(s)
connected to the unit.
7. Warning: Make sure, access is restricted to qualified personnel.
8. Warning: Only licence holders for the respective frequency range are allowed to
operate this unit.
9. Warning: Make sure the repeater settings are correct for the intended use (refer
to the manufacturer product information) and regulatory requirements are met.
10.Warning: Use this equipment only for the purpose specified by the manufacturer.
Do not carry out any modifications or fit any spare parts, which are not sold or
recommended by the manufacturer. This could cause fires, electric shock, or
other injuries.
11.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:
]/[
][
][ 2
4cmmW
mW
cm PD
P
D 

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
oF (MHz) / 1500 for frequencies from 300MHz to 1500MHz
o1 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).
12.Warning: For installations which have to comply with Europe an EN50385
exposure compliance requirements, the following Power Density limits/guidelines
(mW/cm²) according to ICNIRP are valid:
o0.2 for frequencies from 10 MHz to 400 MHz
oF (MHz) / 2000 for frequencies from 400 MHz to 2 GHz
o1 for frequencies from 2 GHz to 300 GHz
13.Caution: Keep operating instructions within easy reach and make them available
to all users.
14.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.
15.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.
16.Caution: ESD precautions must be observed! Before commencing maintenance
work, use the available grounding (earthing) system to connect ESD protection
measures.
17.Note: For a Class A digital device or peripheral:
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at
his own expense.
18.Note: This unit complies with European standard EN60950.
