1.3. Environmental Issues

Thank you for buying a product which contributes to a reduction in pollution, and thereby helps save the

environment. Our products reduce the need for travel and transport and thereby reduce pollution. Our

products have either none or few consumable parts (chemicals, toner, gas, paper). Our products are low

energy consuming products.

1.3.1. TANDBERG's Environmental Policy

Environmental stewardship is important to TANDBERG's culture. As a global company with strong

corporate values, TANDBERG is committed to being an environmental leader and embracing

technologies that help companies, individuals and communities creatively address environmental

challenges.

TANDBERG's environmental objectives are to:

•Develop products that reduce energy consumption, CO emissions, and traffic congestion

•Provide products and services that improve quality of life for our customers

•Produce products that can be recycled or disposed of safely at the end of product life

•Comply with all relevant environmental legislation.

TANDBERG Border Controller User Guide

1.3.2. European Environmental Directives

As a manufacturer of electrical and electronic equipment TANDBERG is responsible for compliance with

the requirements in the European Directives 2002/96/EC (WEEE) and 2002/95/EC (RoHS).

The primary aim of the WEEE Directive and RoHS Directive is to reduce the impact of disposal of

electrical and electronic equipment at end-of-life. The WEEE Directive aims to reduce the amount of

WEEE sent for disposal to landfill or incineration by requiring producers to arrange for collection and

recycling. The RoHS Directive bans the use of certain heavy metals and brominates flame retardants to

reduce the environmental impact of WEEE which is land filled or incinerated.

TANDBERG has implemented necessary process changes to comply with the European RoHS Directive

(2002/95/EC) and the European WEEE Directive (2002/96/EC).

1.3.3. Waste Handling

In order to avoid the dissemination of hazardous substances in our environment and to diminish the

pressure on natural resources, we encourage you to use the appropriate take-back systems in your area.

Those systems will reuse or recycle most of the materials of your end of life equipment in a

sound way.

TANDBERG products put on the market after August 2005 are marked with a crossed-out

wheelie bin symbol that invites you to use those take-back systems.

Please contact your local supplier, the regional waste administration or

http://www.tandberg.net/recycling if you need more information on the collection and recycling system

in your area.

1.3.4. Information for Recyclers

As part of compliance with the European WEEE Directive, TANDBERG provides recycling information on

request for all types of new equipment put on the market in Europe after August 13th 2005.

Please contact TANDBERG at recycl[email protected] and provide the following details for the product

for which you would like to receive recycling information:

•Model number of TANDBERG product

•Your company's name

•Contact name

•Address

•Telephone number

•E-mail address

1.3.5. Digital User Guides

TANDBERG is pleased to announce that we have replaced the printed versions of our User Guides with a

digital CD version. Instead of a range of different user manuals, there is now one CD -- which can be

used with all TANDBERG products -- in a variety of languages. The environmental benefits of this are

significant. The CDs are recyclable and the savings on paper are huge. A simple web-based search

feature helps you directly access the information you need. The contents of the CD can still be printed

locally, whenever needed.
