If the system is in Day mode will be first called the number in the parameter associated with the Day mode button,
then Night and then the third number. If the system is in Night mode will be first called the number associated with
the Night mode button, then Day and then the third number.
This operating mode is particularly useful when you want to get the best chance to contact one of the operators by
the visitor (temporary job sites, other).

Additional features of the keypad expansion
If the expansion module AA-539K is installed, the visitor can make a call simply by dialing the desired number if
known by him or made into an index table placed near the doorphone (eg the AA-539R expansion), typing it
directly on the keyboard.
The introduced numbering is considered finished after about two seconds of entering the last digit by the visitor. It
is possible to speed up the dialing without waiting for the system timeout by pressing the pound key (#) at the end
of the number, in which case the call is made immediately.
The visitor, realizing that has made mistakes in typing can be immediately cancel the entered digits by pressing the
star key (*), the same key has the function to break down if the call already in progress.
In addition to direct dialing mode , the keypad allows for Speed Dial function, in which it is possible to associate a
number to call to each digit of the keyboard (10 phone numbers associated with the digits from 0 to 9), this service
can be enabled via the parameter 149. The numbers are 20 in total as 10 are associated with the digits in the Day
mode and the other 10 can be associated with the same digits in the Night mode.
According to the system mode, the visitor can then contact one of the 20 numbers entered. The Speed Dial mode
is NOT exclusive but coexist with the possibility of direct dialing with the only exception that it is not possible to
directly dial single digit numbers. Having to select the visitor directly to a single-digit numbers it is not possible to
use the Speed Dial service.
The Speed Dial feature (single digit of the keyboard) behaves as pressing a button on the base system and it is
also adjusted according to the parameter 118 about the operation in Day/Night mode, Day/Night with repeating
calls, or Group mode. In practice, for the user it is as were added 10 more buttons that can be used.
By directly dialing the number to call on the keyboard may be possible for the visitor to dial a number that you do
not want to be dialed, or at least reached (eg outside the company). To avoid this possibility it is possible to use the
parameter 150. This is a code that, if programmed, provides to prepend a number to the dialied number. If the
numbers of operators are in the numbering plan of the PBX (internal extensions), it is sufficient to program the
parameter 150 with the first digit of the numbering plan and expose the legend for visitors with numbers to reach
without the first digit. For example, to call the operator at the extension number 311 it must be programmed the
parameter 150 with a value of 3 and indicate to the caller to dial the number 11.
In the case there is the need that the the visitor must dial external numbers this parameter may be useful if filled
with the value of a code that instructs the PBX to use a specific trunk group for outgoing governed by the desired
class of service, with restrictions on certain numbers for calls when the PBX allows it (long distance calls, foreign
calls, fee-based services, mobile network, etc.).
In other cases, remember to activate some sort of control on the possible numbers that a general visitor can dial to
prevent authorized calls.
AA-539 is equipped with a special table of up to 10 numbers that allows to create a filter on the selections made by
the user, in order to allow or reject it, even without the control of the PBX. This table and this service are very
useful for systems equipped with the full keyboard expansion module. See the parameters from 230 to 240 for the
programming of these particular functions.
There is a special code (parameter 178) that allows during a conversation, to enable the keyboard for the issue of
DTMF tones as a normal analog phone, useful when are reached systems or phone services that interact with the
user and must be controlled with DTMF tones.
