Digital Telephone IP Adapter Installation and Administration Guide 245
January 2005 Safety and regulatory information
Electrostatic discharge
The Digital Telephone IP Adapter units are immune to electrostatic discharges
typical for an office environment (carpeted floors, low humidity) according to
the test method specified by IEC 1000-4-2.
No damage or malfunction occurs when the Digital Telephone IP Adapter units
are exposed to up to +/-8kV of direct discharge. An indirect discharge of up to +/
-16 kV does not result in malfunction of the system (to adjacent equipment or
connected cabling).
The requirements for both “closed door” and “open door” have been met.
