Keyboard
The device has three separate keyboards:
• S60 keyboard
• ITU keyboard
• Multimedia keyboard
The S60 keyboard and multimedia keyboard are assembled on the UI/slide module. If there’s failure on these
parts, whole module has to be replaced. ITU keyboard pads are placed directly on the system/RF module.
ITU keyboard is visible, when display is moved upwards. Keypads are on the system/RF module. System/RF
module includes also side keys (volume keys and 2-position camera key).
