number is stored (same as for buttons). The number dialing is
managed by Day/Night setting or mode for two groups of numbers (as
described in Chapter 2.2.1).

from keyboard. This feature it is possible switch on only by

keyboard during talk is OFF. Parameter 40d - d=0 switch off (default),

2.3 Person Inside Object
The person inside object is considered a person that is in phone contact
with Door Phone NUDV.
2.3.1 Outgoing Call
The outgoing call is the call from guard (caused by visitor). After guard
choice the telephone is ringing inside object and the lifting up will allow
speaking to the visitor at door. The code choice can close the switch
(parameter 35), if set to m=1 or m=5 modes, change over the Day/Night modes
(parameters 45,46) and hang up (parameter 43). The guard in 10 seconds
before call end (parameter 52) will send a notice about call end and the call
may be extended by sign selection (parameter 42). The telephone hanging up
will end the call (the exchange is sending a busy tone on guard’s line and the
guard also will hang up).
2.3.2 Incoming Call
The incoming call is the call from guard (caused by person inside object). After
exchange number selection, where the guard is connected, the guard’s line is
ringing and when set number of rings is over (parameter 51), the guard will lift
up and it is possible to speak. The possibilities are the same as with outgoing
call (Chapter 2.3.1).
• Except the first 10 seconds, where extra "# and service password"
(parameter 44) can be entered, the guard then will proceed with
programming mode.
• The other exception of incoming call is by connected “SERVICE” jumper.
The guard after line lifting up proceeds then with programming mode
(without service password).
