Notes about Keyguard
• When Keyguard is on, calls may be possible to the
emergency number programmed into your phone (e.g.
911 or other official emergency number). However, one-
key emergency dialing ('the 9 key') does not operate.
• Keyguard is automatically turned off when the phone is
connected to a car kit.
