4.3 – Write HW Version
When HW version is selected, the current version is read from the phone
and displayed.
4.4 – IMEI Edit
When this selection is made, the old IMEI is requested from EEPROM. If
IMEI is not received within 2 seconds (approx.), an error message is
displayed . Press any key to clear it and return to the previous menu.
If IMEI or EEPROM check sums have the wrong values, an error message
is also displayed. After errors are acknowledged, the editing window is
displayed without data, allowing at least 40 ASCII characters to be edited
in the window. After IMEI data the password must be edited.
IMEI and password data are written to the EEPROM when editing is
ended. The writing must be accepted by the user as with other EEPROM
writing functions. If no response message from MCU to IMEI writing
function is received within a few seconds, an error message is shown.
4.5 – IMEI Transfer
The purpose of this function is to transfer the IMEI code from an old
system board to a new system board. This function is used when system
boards are changed.
The selection, program asks to confirm the function with <Y> key.
Pressing the <N> or <Esc> keys cancels the selection.
After pressing <Y> key the IMEI is read from EEPROM to PC. When the
IMEI code is received by PC, information is displayed and the IMEI code is
destroyed in the EEPROM. After clearing the IMEI number, the old system
board becomes unusable.
Caution: The IMEI is now situated in the PC and quitting the Service
software program at this stage will cause all IMEI data to be lost.
At this time, switch the phone power off, exchange the system boards and
switch the phone power on again. A ”Selftest failed” –message will appear
in the phones display.
After pressing the <Enter> key the IMEI will be transferred to the new
system board. The IMEI data in the PC will be cleared and cannot be used
again.
For resetting the phone you must select the ”Initialize phone” option from
the ”Main menu”. If the phone does not show the ”Selftest failed”message,
the transfer is successful. If the ‘fail’ message is still displayed, contact
your local technical support .
