Adapting to your environment
Your handset has two functions which can be used to adapt the handset to loud environments:
If you activate the function using the menu ❯❯❯ Audio > Ringer settings > Noise detection, the
ringer volume is automatically increased in loud ambient noise. Make sure in this case that you have
not set the ringer volume to “Increasing”.
If you activate this feature using the menu ❯❯❯ Audio > Loud environment, the handset will
attempt to improve the speech quality in a loud environment. This applies to connections via the
handset itself and with a wired headset (but not to Bluetooth headsets and the handsfree mode).
Special functions
Emergency call key (SOS)
All the devices offer the possibility of storing an SOS emergency-call function under one of the pro-
grammable keys (see page 97). To dial an SOS emergency number, all you have to do is briefly press
the programmable key (emergency call key). Whether dialling is possible only in the idle state or
also in the connected state depends on the device and the assigned key type and the system.
If you programmed the SOS emergency call function under the left and middle softkey, the emer-
gency call key is available in the idle state only.
If you program the emergency call function under one of the other keys (left and right navigation
key or sidekeys / Hotkey on the Aastra 620d / 622d / 630d / 632d / 650c), the emergency call key can
also be used in the connection state (depending on the system).
Normally the handset is always switched to handsfree mode when the SOS emergency number is
dialled. On the Aastra 630d / 632d you can set whether the number is dialled in handsfree mode or
in handset operation (see menu item Handsfree in alarm in the event of an alarm under Alarm Sen-
sor).
The Aastra 630d and 632d handset has a separate SOS key on its upper side. You can set the key’s
response in the menu ❯❯❯ -> Security -> SOS call -> SOS key or in the menu ❯❯❯ -> Settings ->
Key programming -> [and press the SOS key]. The settings include: SOS call: immediately (the SOS
emergency number is then dialled directly) or SOS call: with confirmation (the SOS emergency
number is dialled only after a safety prompt). The SOS emergency number is always dialled immedi-
ately if the key is pressed and then held down.
You can enter the SOS emergency number in the menu ❯❯❯ -> Security -> SOS call -> SOS number.
This menu item is not displayed if the SOS emergency number is predefined by the system.
