2.3 Device does not stay ON
If the device is switched off without any visible reason, there may be problems
in the following areas:
S CCONT watch dog problem
S BSI or BTEMP line problem
S Battery line problem
S Soldering problem
The most likely reason is CCONT WD (watchdog) problem, which turns the de-
vice off after about 32 s.
This may be caused by SW problem, MadLinda problem, CCONT problem or
memory problems.
The following tests are recommended:
S General Power Checking
S Clocks
S Memory testing
S CCONT serial interface
If there is something wrong in BSI and BTEMP lines, the device seems to be
dead after battery insertion. However, the regulators in the device are on 10s
before the powerdown.
This mode can easily be detected from the current consumption of the device.
After 10s the current consumption drops almost to 0mA.
In this case check components
C126, C127
R121, R122, R123,
C103, C104,
battery connector X100.
