General information on the Line-key
The line-keys are supported by an ST 30 because an allocated LED is indispensable. Another
condition for meaningful use is that, two keys are always installed for one line.In the „resting“
status,you can get further information about the line by pressing a flashing line-key (e.g.the caller´s
phone number). Press the flashing linen-key in the ‘pick up´ status, take the call.
