Cautions
To ensure proper operation for making emergency calls by using the Audio Assist/SOS button, the telephone system must be installed according to the installation instructions in your
telephone system’s user manual. To verify that the telephone system is operating properly and can successfully make emergency calls to the preset numbers, the telephone system
must be tested immediately after installation, and periodically thereafter, according to the setup and operation instructions in your telephone system’s user’s manual.
The telephone system cannot make an emergency call when other equipment (telephone, answering system, computer modem, etc.) connected to the same phone line is in use.
Do not solely rely on the Audio Assist/SOS button on the cordless handset for getting help in case of emergency. The functionality of the SOS emergency call is dependent on the
phone settings and network availability.
