PPLICATION
The Multiline Telephone application requires a separate upgrade from the UT880
firmware. To perform an upgrade of the Multiline Telephone application requires a
USB or Micro SD drive and the upgrade file downloaded from the NEC support web
site.
1.1 Using a SD Drive
1. Download Multiline Telephone application file to the support PC.
2. Insert Micro SD drive in the support PC.
3. Copy upgrade file to the Micro SD drive.
4. Remove Micro SD drive from the support PC.
5. Insert the Micro SD drive into the UT880. There is a small slot for this drive
located underneath the phone on the front side.
6. Go to desk top of the UT800.
7. Choose the Applications icon at the bottom-center of the desktop.
8. Start Open Manager.
9. Choose the Home (House) icon at the top of the screen. This should take you to
the Micro SD drive.
10. Choose upgrade .apk file. When prompted, agree to the service conditions and
choose to install.
1.2 Using an USB Drive
1. Download Multiline Telephone application file to the support PC.
2. Insert USB drive in the support PC.
For the upgrade file to work the extension must be .apk. Windows will sometimes
change the extension to .zip because it sees an .apk extension as an archive file.
Make sure the extension is .apk when copied to the Micro SD drive or the upgrade
will not work.
