Procedure
Step 1 Obtain the CAPF authentication string that was set when the CAPF was
configured.
Step 2 Choose Settings > Security Configuration.
Step 3 To open the menu, press the Select button.
Step 4 Scroll to LSC and press * * # to unlock the option.
Step 5 Press the Update softkey.
The phone prompts for an authentication string.
Step 6 Enter the authentication string and press the Submit softkey.
The phone begins to install, update, or remove the LSC, depending on how the
CAPF was configured. During the procedure, a series of messages appears in the
LSC option field in the Security Configuration menu so that you can monitor
progress. When the procedure completes successfully, the phone will display
Installed or Not Installed.
The LSC install, update, or removal process can take a long time to complete. You
can stop the process at any time by pressing the Stop softkey from the Security
Configuration menu. (Settings must be unlocked before you can press this
softkey.)
When the phone successfully completes the installation procedure, it displays
“Success.” If the phone displays, “Failed,” the authorization string may be
incorrect or the phone may not enabled for upgrading. Refer to error messages
generated by the CAPF and take appropriate actions.
You can verify that an LSC is installed on the phone by choosing Settings >
Security Configuration and ensuring that the LSC setting shows Installed.
