Two-way calling
After you have accepted the call, you can deacti-
vate the "hands-free call" function by pressing the
speech key. Communication from the internal unit
to the door unit is possible for as long as you
press the speech key. If the speech key is not
pressed, then only communication from the door
unit to the internal unit is possible. The "two-way
call" function is only activated for the duration of
the call.
Switching off the ring tone
Press the ring-tone on/off key continuously (for
approx. 5 seconds) until you hear 3 equally long
confirmation tones. The ring tone is now switched
off. The open door key flashes once per second to
confirm this.
After 12 hours or after a power supply cut-
off, the ring tone is automatically switched
back on.
Switching on the ring tone
Press the ring-tone on/off key briefly. You will hear
an uninterrupted high tone. The ring tone is now
switched on again.
Opening the door
When the door bell rings, you have 2.5 minutes to
open the door with the open door key.
