14 International Mobile Equipment Identity, IMEI

The mobile equipment is uniquely identified by the International Mobile Equipment
Identity, IMEI, which consists of 15 digits. Type approval granted to a type of mobile is
allocated 6 digits. The final assembly code is used to identify the final assembly plant
and is assigned with 2 digits. 6 digits have been allocated for the equipment serial
number for manufacturer and the last digit is spare.

CF61 series IMEI label is accessible by removing the battery.

Re – use of IMEI label is possible by using a hair – dryer to remove the IMEI label.

Date code is shown on IMEI label: Detailed description on how to read date code is
given in Annex 2.

To display the IMEI number, exit code and SW/HW version, key: * # 300 #
Code *#301# activates self diagnosis.

GSM Test:

With the availability of the GRT Test /Alignment software, this tool has to be used to
perform the outgoing test!

>Connect the mobile/board via internal antenna (antenna coupler) and external antenna
(car cradle/universal antenna clip) to a GSM tester
>Use a Test SIM

For Triple Band phones use a separate test case, if the test software allows only one
handover.
Skip the GSM Band test cases if not performed by the mobile phone

Example: 1. Test file Band 1 = GSM900 / Band 2 = GSM1800

2. Test file Band 1 = GSM1900
