A Master Reset forces a Nextel phone to refresh it's network settings. This is useful whenever Nextel has reconfigured your phone, particulary when you've switched from a Private IP (the default) to a Public IP (required by Ranger Mobile Application).

To perform a Master Reset:

1. Press the “red hangup” button twice to return to home screen of the phone.
2. Press the Menu key.
3. Scroll to Settings and press OK key. Note that Settings might be on Page 2, and if so, you need to press More to see it.
4. Scroll to Advanced and press the OK key.
5. Scroll to Connectivity and press the OK key.
6. Scroll to Master Reset and press the OK key.
7. Enter “000000” (six zeroes) for the Security Code and choose OK.
8. Press YES to confirm.
9. Press the OK key if warned to “see manual”. The phone will turn itself off.
10. Wait 60 seconds, then turn the phone back on. The phone will power up.
11. If the phone prompts to “update your browser info,” choose OK.
