Setup
How does SOS emergency call work?
• To make an emergency call, press and hold SOS on the right side of the cordless handset
for three seconds. The telephone base announces "Emergency mode is activated" and
the cordless handset screen shows SOS mode. The telephone then calls the preset SOS
numbers in sequence until the call is answered.
- You can enable internal SOS calls (see page 16). The telephone makes intercom calls to all the
registered system devices when you press and hold SOS. If none of the devices answer the call in 20
seconds, the telephone then calls the preset SOS numbers in sequence until the call is answered.
- If you disable internal SOS calls, the telephone calls the preset SOS numbers directly when you
press and hold SOS on the cordless handset.
• When the call is answered, the call receiver hears an SOS message. You can record your
own message or use the default message (see page 17).
• The SOS message played by the telephone asks the SOS call receiver to respond by
pressing a number key. After the call receiver presses a number key, you can then talk to
the call receiver.
• When the SOS emergency call is answered by answering machine or voicemail, the call
will be terminated after 60 seconds. The telephone then dials the next SOS number in
sequence.
• When none of the preset SOS numbers answer, the telephone re-calls the preset SOS
numbers in sequence until the call is answered. The telephone will call all the preset SOS
numbers for 3 times before aborting the operation when none of the calls are answered.
