Restoring Factory Default State
In some cases, you may need to restore your device to the factory default state
by clearing the memory from your device. For example, you should clear the memory:
 When your device does not respond after being restarted.
 When you forget your password.
Clearing the memory means all data you have entered in your device’s memory,
including all files, system settings and additional programs you have installed, will
be erased. (Programs installed to ROM at the factory are not affected.)
CAUTION: To ensure the integrity of your data should it be necessary to clear the
memory, you are advised to regularly back up your data.
Follow this procedure to clear the memory from your device:
1. Remove the battery and then replace it.
2. Press and hold the Send and End buttons, and then press the power button.
Release all three buttons when the device vibrates.
3. Your device turns on. The words ‚Clean Boot‛ appears on the upper left corner
of the screen.
4. Tap the screen to set up your Windows® Phone.
