This display is used to toggle the BTS_TEST flag in EEPROM. If BTS_TEST is set then
each time the mobile sends a search list it uses only the carrier number stored on
SIM phonebook location 33. Also the neighbour information from system information
messages is ignored. If the BTS_TEST flag is not set, then the value of SIM phonebook
location 33 is ignored and the mobile behaves normally (i.e. does neighbour
measurements according to GSM specifications).
To activate BTS TEST perform the following steps:
- Save desired channel number in SIM phonebook location 33
- Select display 17 in execute mode
- Switch power off and on OR force a cell reselection
If activation succeeded, you will read "BTS TEST ON" in display 17. The 6210 will
show "BTS TEST REQUESTED" instead.
To deactivate BTS tests either select display 17 in execute mode or save a number in
SIM phonebook location 33 which does NOT represent a valid carrier number, then
switch power off and on OR force a cell reselection
CAUTION! The display does not show the value of the BTS_TEST flag in EEPROM. Although
the value is set, BTS_TEST can show to be off. If there is no legal carrier number in
SIM phonebook location 33 (GSM900: 1-124, GSM1800: 512-885, EGSM: 0, 975-1023) 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 a different value from
the one in EEPROM.

This test is meant to be used when some cells are tested before taking them into
commercial use. By setting the CELL_BARRED to on in the base station normal GSM
phones will not try to camp on these barred cells.
By selecting CELL BARR REVERSE, the MS will only use the cells which have CELL_BARRED
set.
By selecting CELL BARR DISCARD, the MS will use all cells, irrespective wether
CELL_BARRED is set or not.
NOTE: If a cell has been selected before barring state in phone is changed the
selected cell will remain the current cell. After the next cell reselection the cell
barring state is working as expected.
