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.

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,

CO2emissions, 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.

European Environmental Directives

As a manufacturer of electrical and electronic equipment TANDBERG is responsible for compli-

ance 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).

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 Gatekeeper User Manual

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.

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 [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

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. In addition, the TANDBERG video systems now have an intuitive on-screen help function,

which provides a range of useful features and tips. The contents of the CD can still be printed

locally, whenever needed.
