Note that power–off test (if passed) turns power off and power should be recon-
nected by using the phones keypad after the successful test. After the power
has been connected to phone, the normal start–up routines are made and the
self–test results are shown in the MCU self–tests menu (i.e. all other than pow-
er–up self–tests are in NOT EXECUTED state after the power–up routines).
Test results will be one of the next: no response, OK, NOT EXECUTED,
FAILED. Note that power–off test have no values, because if test has been
passed, power has been turned off. If power–off test fails a special error mes-
sage window is shown. If no response is received to power off test message in
a few seconds, the user is informed by special info window, where user is
asked to turn the power on and then press the return key.
3.8 – Set MCU Start–up Self–tests
This menu is used for changing the state of the EEPROM selectable tests.
When selection is ”on”, the test will be run every time when automatic start–up
self–tests are activated (e.g. in power–up).
When menu is selected, the previous values will be read from the MCU EE-
PROM and shown on the screen. When <Esc> is used, user is asked to con-
firm the EEPROM values saving. Error handling is done as in other functions
which read and save EEPROM values.
