Notes about Keyguard
• When Keyguard is on, the only way to answer a call is to
press $QVZHU .
• 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-touch emergency dialing ('emergency key 9') does
not operate.
• Keyguard is automatically turned off when the phone is
connected to a car kit.
