exceeds the protection level cited in the approval specification. Elevated ESD levels should nevertheless be
avoided to the greatest possible extent. In some cases, electrostatic discharge levels can far exceed the ap

proval limits or the resistance levels already implemented in your telephones. Eliminate the causes or con
-
ditions 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.
