MWI with special ring tone 
When the switch is set to SR (Special Ring), the LED flashes when the telecommu-
nication system sends a special ring tone. This special ring tone is made up of three 
parts, T1---T2---T3. The times for T1---T2---T3 can be set (see also Page 24, "Set-
tings").  
T1 (1st call signal frequency = 50Hz, duration = 0 to 990 ms) 
T2 (call signal pause with duration = 0 to 990 ms) 
T3 (2nd call signal frequency = 50Hz, duration = 0 to 990 ms) 
This type of MWI is supported for example by the Siemens HighPath 3550 and 3750 
systems. Settings expected for the Siemens system: T1=040, T2=110, T3=040. 
Settings expected for NEC telephone systems: T1=150, T2=330, T3=150. 
However, we strongly recommend discussing the settings with the technician who 
set up the system. 
To disable the MWI, press ESC or simply pick up the receiver.
