Setting the standard on environmental

In designing the Dialog 4000 digital tele-
phones, great attention has been given to
ensuring that the telephones are environ-
mentally sound throughout their entire life
cycle.
• All plastic parts in the telephones are
completely free from brominated flame
retardants.
• It is compulsory for our suppliers to
comply with Ericsson’s list of Banned
and Restricted Substances. In this way,
we ensure that our telephones do not
contain hazardous materials.
• The Dialog telephones have been
constructed to minimize on energy
consumption throughout the production
phase. We also ensure low waste during
production.
• Ericsson incorporated a defined recycling
procedure when designing the Dialog
telephones. All major plastic parts bear
material identification. The markings are
easily visible during dismantling and
disassembly. For simple recycling all
labels are made of a material that is
compatible with supporting material.
the cornerstone in the Dialog 4000 design process, making for industry-leading environ-
mental performance.
The Dialog 4000 family of telephones lead the way into the future for enterprise communi-
cation. There are five models in this family of telephones that include ‘Lite’, ‘Office’,
‘Professional’, ‘Operator and the multi-featured ‘Vision’.
• All telephone cords are PVC-free.
Alternatively, Poly-Urethane cords are
used which are of high quality and also
environmentally sound.
• We have worked on developing the
Dialog telephones to be highly energy
effective. Power consumption has never
been at a lower level than on these
telephones.
• The telephone terminals are constructed
to comply with the White House
Executive Order on standby power
mode.
• Ericsson use recyclable paper material
for packaging the telephones. We insist
that no plastic material whatsoever
should be used.
