Speed Dial Buttons
Press the speed dial buttons on the basic unit to make quick dialling for the first 1 or 2
(depending on the model type) in the telephone directory. Call setup is signalled by a
long intermittent tone or otherwise as configured in the PBX connected.
Repeated pressing of one and the same speed dial button during call setup may initiate
call termination, or call termination plus dialling the next telephone number of the
called subscriber, or may be assigned no function.
