Please note that if you do these next tricks,
the new menus can't be erased without retoring the
factory default settings. To do these tricks you need
to short-circuit the pins on the bottom of the phone
next to where you plug in you charger.
1. To activate the "Headset" menu, you need to short-circuit
pins "3" and "4". After a short time the word "Headset" will
be shown in the display. Menu 3-6 is now enabled.
2. To activate the "Car" menu, you need to short-circuit pins
"4" and "5". After a short time the word "Car" will be shown
in the display. Menu 3-7 is now enabled.
