Updating Phone Software
The update phone software option allows you to download
and update the software in your phone over the air. Only the
internal software is updated; no Contacts entries or other
information saved to your phone will be deleted.
To update your phone:
ᮣ
Select Menu > Tools > Update Phone S/W.
Follow the onscreen instructions.
Note: If your phone’s signal strength is low, Update Phone S/W may
not be completed. Please update your phone when you’re in
an area with better signal strength.
