Sound Settings
From this menu you can control the sounds on the phone as
well as configure the display settings.
Ⅲ Press ➔ and then tap Settings ➔ Sound.
The following options display:
Silent mode via Device Options Screen
Silent mode is convenient when you wish to stop the phone
from making noise, in a theater for example. In Silent Mode
the speaker is muted and the phone only vibrates to notify
you of incoming calls, or other functions that normally have a
defined tone or sound as an alert.
1. From the Home screen, press and hold the Lock key
until Device options displays.
2. Tap Silent mode from the Device Options screen to
activate or deactivate this mode (the current mode
displays).
Setup Device Vibration
1. Press ➔ and then tap Settings ➔ Sound.
2. Tap Silent mode.
3. From the Silent mode menu, select either Vibrate or
Mute.
Note: This setting is independent of other call sounds settings.
For example, if you have Silent mode enabled along with
Vibrate, your device won’t play a ringtone, but will
vibrate for an incoming call.
Note: Use both the Silent mode and enable the Mute option to
guarantee no vibrations or sounds from your device.
This really helps at night so you don’t wake up hearing
your device vibrating on a nearby counter or table.
