Contacting Emergency Services
This handset, like any wireless phone, communicates over radio signals. As with any wireless
phone, you may not be able to establish a connection under all conditions. Therefore, you should
never rely solely on a wireless telephone for essential communication (for example, in medical
emergencies).You can program an emergency number into the SOS key on your handset (see
Using the SOS Key on page 15).
The Key Lock feature disables the handset keypad and prevents the accidental dialing of
numbers that could result in nuisance calls. It also prevents accidental calls to emergency
services numbers (for example 999, 911 or 112).
