Key functions
In the subsequent sections of this document the touch keys are designated as shown in the gure below:
T3 (F1)
P/A (ANSWER / END
CONVERSATION)
T4 (USER ABSENT /
MUTE MICROPHONE)
M (ACCESS
CONFIGURATION)
DOOR LOCK
T2 (STAIR LIGHT)
T1 (SELF-START)
Keys T1..T4 have two operating contexts:
• Operators
• Intercom
In the Operators context, keys T1..T4, have the default function (when not programmed) indicated in the gure
above. They can only be programmed using SaveProg.
In the Intercom context keys T1..T4 are not programmed by default. They can be programmed from the installer
menu or using SaveProg.
T4 has the functions user absent / mute microphone only when it is not programmed. If T4 is used for a Operators function, the default function will be lost and it will not be possible to assign it to any other key. If T4 has
the default function, the associated LED will operate also as an indicator for :
• User absent (the internal unit rejects the call from an external unit and consequently the call is unsuccessful)
• Ringer disabled (the internal unit does not ring for calls from the external unit, but otherwise functions
normally)
essential when the display is switched off. It remains on, switching off briey for 1, 2, 3 or a maximum of 4 times
each cycle, according to the number of calls received when user absent is activated. If the user absentfunction
is absent, the icon
is displayed at the top and on T4 to indicate that T4 will re-activate the ringer.
If the ringer disabled function is activated (see User Conguration), no icon is associated with T4 because
ringer disabled has priority over user absent.
The M key cannot be programmed and its function is context-dependent.
The P/A key also has the function of activating the Intercom, if there is at least one programmed key or if ag
7 in SaveProg is activated (default) (Switchboard mode).
By default, the LOCK key, as in all internal units, controls the lock of the last external unit to make a call or
the external unit for which self-start procedure was performed. It can only be programmed using SaveProg.
The LED associated with the LOCK key indicates door open status of the system, essential when the display
is switched of, even if the same key is programmed for another function. It can also indicate the status of the
Alert, described later in this manual.
In standby mode, the screen is completely switched off. Touching any of the keys T1..T4, M, P/A (only if it has a
function) turns on the display, but without executing any function. If the LOCK key is set to its default function, the
function is executed without switching on the display. If the key has been programmed, no function is executed
but the display is switched on, as with the other keys.
