Warnings
Warnings
2.1
Personnel
Installation, commissioning and maintenance measures concerning any Nokia
Base Station (BTS) may only be performed by properly trained and authorised
personnel. Nokia InSite Base Station must be installed so that only the authorised
personnel have access to its sensitive parts.
2.2
Dangerous voltage
Potentially lethal voltages are present within this system. For more information
on power supply, seeRequirements for Installation and Operation.
WARNING
MAINS VOLTAGE! Follow all applicable national legislation when working
with the power supply.
The AC cord set shall be in accordance with all applicable national wiring
rules.
The mains plug will act as a disconnecting device for AC mains and no other
AC disconnecting device is needed. The power is always ON when the mains
power cable (AC cable) is connected!
The power supply unit feeds power to the BTS even after the AC has been
disconnected. To stop the power feeding, the DC cable has to be disconnected
also.

Nokia InSite Base Station Warnings and Cautions, DRAFT
WARNING
Opening the back cover of the power supply unit is strictly forbidden!
WARNING
Do not disconnect the possible external antenna connector when Nokia
InSite Base Station is powered on.
WARNING
When choosing the installation location and drilling the holes, make sure
that you do not damage any cables that may be routed behind the wall.
WARNING
Follow all applicable national regulations when choosing the possible cable
cover types and installing the cable covers.
2.3
Electromagnetic fields and RF power
Nokia InSite Base Station generates electromagnetic radiation, which very close
to the antennas can exceed safety levels. Observe the general guidelines presented
in Section 2.3.1.
2.3.1
General guidelines
WARNING
This equipment generates electromagnetic radiation which can exceed safety
levels when a person is working at a distance less than 10 cm (4 in) from the
antennas. Observe the 10 cm (4 in) distance precautions when working in
close proximity to antennas operating in full power.

Warnings
WARNING
Do not install Nokia InSite Base Station or its antennas in areas where there
is a potential risk for interference with inadequately shielded medical
equipment, such as life supporting devices, hearing aids or other electrically
or magnetically sensitive devices!
WARNING
When installing Nokia InSite Base Station or its antennas, the emission of
other antennas nearby has to be known beforehand so that ambient
emissions can be managed properly.
2.3.2
Compliance with ICNIRP basic restrictions
A substantial amount of scientific research conducted all over the world over
many years demonstrates that radio signals within established safety levels
emitted from mobile telephones and their base stations present no adverse effects
to human health.
There exist national and international safety guidelines for exposure of the public
to radio waves:
•
International Commision on Non- Ionizing Radiation Protection
(ICNIRP): Guidelines for limiting exposure to time varying electric,
magnetic and electromagnetic fields. Health Physics 1998 74(4): 494-522.
•
Institute of Electrical and Electronics Engineers (IEEE): IEEE Standard
for safety levels with respect to human exposure to radio frequency
electromagnetic fields, 3 kHz to 300 GHz. IEEE C95.1-1991 (revision of
ANSI C95.1-1982) New York 1992.
•
CENELEC: Human exposure to electromagnetic fields. High frequency
(10 kHz to 300 GHz). European prestandard ENV 50166-2, Brussels 1995.
The most widely accepted standards are those developed by the International
Commission on Non-Ionizing Radiation Protection (ICNIRP) and Institute of
Electrical and Electronics Engineers (IEEE). Nokia InSite Base Stations must be
installed according to instructions specified by Nokia, as well as taking any
country-specific regulations for Non-Ionizing radiation protection into account.
Nokia InSite Base Station’s maximum output power at the antenna connector is
19 dBm for 900 MHz and 22 dBm for 1800/1900 Mhz frequency variants. The
antenna gain is 2 dBi and 4 dBi respectively. It is important to note that an
additional 6 dB increase in power density may occur due to installing a Nokia
InSite Base Station on a conductive surface.

Nokia InSite Base Station Warnings and Cautions, DRAFT
The exposure limits of local SAR defined by ICNIRP (2 W/kg averaged over 10
g tissue, as stated in International Commision on Non-Ionizing Radiation
protection (ICNIRP): Guidelines for limiting exposure to time varying electric,
magnetic and electromagnetic fields. Health Physics 1998 74(4): 494-522.) are
not exceeded at the distance of 10 cm (4 in) from the integrated antenna of 900
MHz, 1800 MHz or 1900 MHz frequency variants of Nokia InSite Base Station.
All applicable national regulations shall be followed when Nokia InSite Base
Stations are being installed.

circulation of air, the air inlets and outlets must not be obstructed.
Caution
Nokia InSite BTS and the power supply can only be installed in a vertical
position. This is for the cooling to work properly, and it is also vital for the power
supply unit battery lifetime. Nokia InSite BTS or the power supply unit must not
be installed upside down.
3.2
Power supply to Nokia InSite Base Station
Caution
Nokia InSite Base Station must only be used with Nokia power supply unit PBU11.
