Elektrostatic charges (protection against electrostatic charges)
The telephone is supplied with enhanced ESD protection against the effects of electrostatic
discharge that exceeds the protection level cited in the approval specification. Elevated ESD le-
vels should nevertheless be avoided to the greatest possible extent. In some cases, electrostatic
discharge levels can far exceed the approval limits or the resistance levels already implemented
in your telephones. Eliminate the causes or conditions that promote these elevated ESD levels,
such as insufficient humidity or carpeting. The telephone manufacturer does not assume any
liability for damage caused under such circumstances.
