Software Maintenance
The NEC MH150/MH160 Mobile Handsets software is maintained by NEC
Unified Solutions, Inc. The software versions that are running on the
handsets can be displayed during power on by holding down the END
button. Firmware Version is also an option on the Config menu.
NEC Unified Solutions, Inc. Customer Service or an authorized associate
will provide information about software updates and how to obtain the
software.
Upgrading Handsets
After software updates are obtained from NEC Unified Solutions, Inc.,
they must be transferred to the appropriate location in the LAN to
update the code used by the handsets.
NEC MH150/MH160 Mobile Handsets allow over-the-air transfer of
software updates from the designated TFTP server to the handsets. The
downloader function in the handset checks its software version every
time the handset is turned on. If there is any discrepancy the handset
immediately begins to download the update.
Normal Download Messages
When the handset is powered on, it displays a series of messages
indicating that it is searching for new software, checking the versions,
and downloading. The normal message progression is shown in
Table 11-1.
