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.
