A temperature level approximation can be obtained using the following 5th order polynomial
formula:
Temp [C] = A5* ADCp5 + A4* ADCp4 + A3* ADCp3 +A2* ADCp2 +A1* ADCp1 +A0
A5 = -1.3e-09, A4=8.91591e-07, A3=-0.00024, A2=0.032894, A1=-2.56084, A0=103.2997
• ADCpN means ADC value powered by N
• XeY means X*(10 powered by Y)

Antenna Presence
Antenna presence measurement reports whether antenna is attached or not.
MIDlet Watchdog
The watchdog is a guard that keeps the system alive, and will restart the G24 when a MIDlet
lockup is detected.
Once it is activated platform initiates a timer. Timer expiry is considered a MIDlet lockup.
UM should kick the watchdog timer in order to reset it.
