● Do not remove the battery pack while updating the software. The software update may fail if
you do so.
● The software update can be made with data, such as Phonebook entries, images recorded
by the camera and downloaded data, remaining in the FOMA terminal. However, note
that the safety of the data may not be assured depending on the conditions of your FOMA
terminal (e.g. malfunction, damage and exposure to water). It is recommended to take a
backup copy of important data (some data such as downloaded data may be protected
from backup copy).

 It may take time to update (download and rewrite) the software in some cases.
 The Alarm and Schedule alarm do not operate while updating the software.
 You cannot place or receive a call, and use various communication functions and other functions
while updating the software. (You can receive a voice call while downloading the software.)
 The FOMA terminal uses SSL communication with the DoCoMo server to update the software.
Before starting update, set the SSL list to [Valid] (Default: [Valid]) (P.198).
 It is recommended to update the software under strong radio wave condition with 3-antenna
marks displayed and not to move the FOMA terminal while updating the software.
※ When the weakening of the radio wave occurs while downloading the software or the
download is interrupted for any reason, perform the software update again in a location of
good radio wave condition.
 If no new update is available, the message "No update is needed. Please continue to use as
before" appears when you check the necessity of the update.
 After updating the software, icons that notify you about mail/messages stored at the i-mode
center disappears. When the Recv option setting is [ON], the screen notifying you of new mail
may not be displayed after completion of the update if there is new mail while updating the
software.
 When you update the software, your FOMA terminal-specific information (such as model
and manufacturer's serial number) is automatically sent to the server (server for updating the
software under DoCoMo's supervision). DoCoMo will not use the information sent from your
mobile phone for any purposes other than to update the software.

is possible. In this case, please bring the FOMA terminal to the nearest DoCoMo repair
handling service counter.
