1.4 History of changes

1.5 Waste electrical and electronic equipment (WEEE)

All waste electrical and electronic products must be disposed of separately from the

municipal waste stream via designated collection facilities appointed by the governmentor the local authorities. The WEEE label (see Figure 1) is applied to all such devices.

Figure 1 WEEE label

The correct disposal and separate collection of waste equipment will help prevent poten-

tial negative consequences for the environment and human health. It is a preconditionfor reuse and recycling of used electrical and electronic equipment.

For more detailed information about disposal of such equipment, please contact Nokia

Siemens Networks.

The above statements are fully valid only for equipment installed in the countries of the

European Union and is covered by the directive 2002/96/EC. Countries outside the

European Union may have other regulations regarding the disposal of electrical and

electronic equipment.

1.6 RoHS compliance

FlexiPacket MultiRadio complies with the European Union RoHS Directive 2002/95/EC

on the restriction of use of certain hazardous substances in electrical and electronic

equipment.

The directive applies to the use of lead, mercury, cadmium, hexavalent chromium, poly-

brominated biphenyls (PBB), and polybrominated diphenylethers (PBDE) in electrical

and electronic equipment put on the market after 1 July 2006.

Materials usage information on Nokia Siemens Networks Electronic Information

Products imported or sold in the Peoples Republic of China

FlexiPacket MultiRadio complies with the Chinese standard SJ/T 11364-2006 on the

restriction of the use of certain hazardous substances in electrical and electronic equip-

ment. The standard applies to the use of lead, mercury, cadmium, hexavalent chro-

mium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE) in

electrical and electronic equipment put on the market after 1 March 2007.

1.7 Safety instructions

In this paragraph are indicated all the safety rules and the precautionary measures to

follow while carrying out operations on the equipment in order to prevent injuries to per-

sonnel and/or damages to the equipment components.

t PLEASE READ THESE SAFETY PRECAUTIONS!

1.7.1 RF Energy Health Hazard

This symbol indicates a risk of personal injury due to radio frequency exposure.

The radio equipment described in this guide uses radio frequency transmitters.

No one shall be allowed to come in the close proximity of the antenna's front while the

transmitter is operating. The antenna will be professionally installed on the outdoor per-manent fix-mounted structures in order to keep it separate from any other antenna and

from everybody else.

f WARNING!RF Energy Exposure Limits and Applicable Rules for 6-38 GHz. It is recommended that

for each radio equipment deployment site the radio equipment operator refers to the RF

exposure rules and precaution for each frequency band and to all other applicable rules

and precautions with respect to transmitters, facilities, and operations that may affect

the environment due to the RF emissions.


11/17

A25000-A1600-A020-01-76P1

Appropriate warning signs must be properly placed and affixed at the equipment site and

access entries.

1.7.2 Protection against Lightning

Article 810 of the US National Electric Department of Energy Handbook 1996 specifies

that radio and television lead-in cables must have adequate surge protection at or near

the point of entry to the building. The code specifies that any shielded cable from an

external antenna must have the shield directly connected to a 10 AWG wire that

connects to the building ground electrode.

Do not turn on power before reading product documentation. This device has a -48 VDC

direct current input.

1.7.3 Protection from RF Burns

It is dangerous to stare into or stand in front of an active antenna aperture. Do not stand

in front of or look into an antenna without first ensuring that the associated transmitter

or transmitters are switched off. Do not stare into the waveguide port of an ODU (if appli-

cable) when the radio is active.

1.7.4 Warning Turn off all power before servicing

f WARNING!Turn off all power before servicing.
