8.3 Flip fault.
Make sure that the little plastic "spike" that pushes the little button just below 0 and
# isn´t broken. If it is broken, change the flip and try again. If the fault remains, open
the fault and check for liquid damages, especially around the little button men-
tioned above (Fig 8.4). Wash the keyboard pad properly and put the phone together
again using a new keybord. If the fault still remains, proceed to section 8.4 (the but-
ton to the flip is called Flip in Fig 8.3).

8.4 Keyboard fault.
Open the phone and check for liquid damages, especially around the buttons that
don´t work. Wash the keyboard pads properly and put the phone together again
using a new keyboard. Check the phone again according to section 8.2. If that didn´t
work, open the phone and check the solderings on D600:1 (Fig 8.2) and D600:120-
128. If they are fine, give the board power and start it up. Measure VDIG (3.2 V) on
the side of C600 that is marked (Fig 8.2). If VDIG is incorrect, proceed to chapter 3
("Doesn´t start"-fault).
Function chart is shown in Fig 8.3.
