    This display is used to toggle BTS_TEST status on EEPROM. If BTS_TEST
    status is set on EEPROM each time the mobile sends a search list it uses
    only the carrier number stored on SIM SCM-location 33. Also the neighbour
    information from system information messages is ignored. If the BTS_TEST
    status is not set, then the value of SIM SCM-location 33 is ignored and the
    mobile behaves normally (i.e. does the neighbour measurements according the
    GSM specifications).

    To activate BTS tests perform following steps:
        - Save desired channel number in SIM SCM-location 33.
        - Select display 17 in execute mode
        - Switch power off and on
    If activation succeeded, there is text "BTS TEST ON" in display 17.

    To deactivate BTS tests either select display 17 in execute mode or
    save number 0 in SIM SCM-location 33 and switch power off and on.

    NOTE! The display does not show the value of BTS_TEST status in EEPROM.
    Although the value is set, bts test can be off. If there is not legal
    carrier number in SIM location 33 (GSM: 1-124, DCS1800: 512-885) the
    display shows that bts test is off. Also if the mobile was already
    registered to some carrier before switching BTS_TEST status, the display
    can show different value from the one in EEPROM.
