Erasing the Local Configuration
Erasing the Local Configuration
You can clear all locally stored configuration options in a phone by using the
Phone Settings menu. When you use the restore to factory default option, all
user-defined entries in Network Profiles, Phone Settings, and Call History are
erased.
To erase the local configuration, follow these steps:
Procedure
Step 1 Choose Settings > Phone Settings.
Step 2 Press **2 on the keypad.
The phone briefly displays “Start factory reset now?”
Step 3 Press the Ye s softkey. All settings are deleted.
The phone cycles through normal startup procedures.
Or press No to cancel the reset.
Step 4 Press Settings > Network Profiles to reconfigure the network settings for your
WLAN.
Caution Erasing the local configuration removes network profiles that are set up for the
Cisco
Unified Wireless IP Phone to access the WLAN. You must reconfigure the
network settings after performing the reset to enable the phone to access the
WLAN.
