Note: You can make emergency calls on a
locked phone (see page 62). A locked phone
still rings or vibrates for incoming calls or
messages, but you need to unlock it to

lock & unlock external
keys
When your phone is closed, your external
keys (such as the smart key and volume keys)
lock to prevent accidental key presses.
Note: Your phone will not lock external keys if
an action is in process. For instance, if you
close your phone and press a volume key
right away, your phone shows your ring style
profile. Your external keys remain unlocked
until you close the ring style profile.
To change how long your phone waits before
it automatically locks your external keys:
s > w Settings > Security > External Key Lock
> Timer > a time interval or Off
Note: If you choose Off, you can still manually
lock your external keys by holding the
smart key.
To unlock your external keys, press and hold
the smart/PTT key (the key below your
volume keys).
