This mobile phone uses a single color screen, large fonts and orange LED backlighting to help elderly users with eye degeneration. The settings are simplified, select numbers using Up and Down buttons. Each of the four buttons on the side has one function: volume control, FM, light and lock/unlock which can be turned on/off by a simple slide. A unique SOS button at the bottom dials the preset number until answered for emergencies. There are three icons on the keypad: the girl represents the daughter's number and the boy represents the son's number while the horn symbol represents the hearing aid function. Ultra low radiation!
