| 17 Pirelli's fw also has a user-accessible debug mode for the vibrator: *#2003# | |
| 18 puts the vibrator into the same state as for incoming calls, where it pulses | |
| 19 continuously until stopped with another *#2003# command. The 1 s pulsing feels | |
| 20 exactly the same whether it's an actual incoming call or *#2003# test mode. | |

| 22 At FreeCalypso HQ we have a decased Pirelli motherboard that has the LCD and | |
| 23 keypad still attached, but no other peripherals. Turning on *#2003# test mode | |
| 24 and putting an oscilloscope probe on an accessible test point in the vibrator | |
| 25 driving circuit has revealed the vibrator pulse sequence to be 500 ms on, 500 ms | |
| 26 off, endlessly repeating. |
