Resetting to Factory Settings
When some issues occur on your phone and you have tried all troubleshooting suggestions but still do not solve the
problem, you can reset your phone to factory configurations.
This operation will delete all your personal configuration settings, and reset all settings to the factory defaults. Check
with your system administrator if the personalized settings are kept before resetting your phone to factory settings.

On the T42S/T42G/T41S/T41P/T40P/T40G phones, navigate to Menu > Settings > Advanced Settings (default pass-
word: admin) > Reset Config.
2. Select Reset to Factory Settings > Reset.
The phone prompts you whether to reset the setting.
3. Select OK.
The phone begins resetting.
Tip
You can also long press the OK key when the phone is idle.
After reset, the screen prompts “Welcome Initializing…Please wait”.
The phone will be reset successfully after startup.
Note
Reset of your phone may take a few minutes. Do not power off until the phone has started up successfully.
