The Siemens Gigaset SL78 h Twin Additional Handsets meet the highest standards regarding design, technology and environmental friendliness. A unique design concept using solid metal underscores the high quality of the handset and charging cradle. Special emphasis is placed on ease of use - users can move through the newly designed menu system with its intuitive icons using a central 5-way navigation key (four direction keys plus a middle key) on the handset. Metal dome key technology with its clear pressure point gives a completely new feel. Ideal legibility is ensured by the large TFT QVGA color display with 256,000 colors (240 x 320 pixels). In addition, the SL 78 Twin handsets offer excellent sound quality even when used in full-duplex handsfree mode.
