information:
During a flash download, the M3902, M3903, and M3905 telephones
display messages on the displays at the right. (See Figure 43 on
page 271) Display 1 shows the “Erasing Flash Memory” message along
with blocks written to the second line (each with decreasing contrast).
This is followed by Display 2 that reads “Awaiting Download.”
Display 3 flashes the text “Downloading Firmware” on the first line with
progress bars on the second line.
When all 24 segments of the progress bars are displayed as shown, the
download is complete. The telephone then resets and returns to service.
All user-controlled parameters, such as screen contrast, volume settings,
and key labels are not affected by the firmware download. In the event
that the firmware download was not successful, the text “Terminal Out
of Service is displayed on the first line. In some cases, the telephone
erases the flash memory, showing Display 1 followed by Display 2.
