Contacting Emergency Services
This handset, like any wireless phone, communicates using radio signals. As with any wireless phone, you may not be able to establish a connection under all conditions; therefore, you should not rely solely on a wireless telephone for essential, emergency communication. The key lock feature disables the handset keypad and prevents the accidental dialing of numbers that may result in nuisance calls. It also prevents accidental calls to emergency services numbers like 911, 999, or 112.
