The OpenScape DECT Phone SL6 is the slimmest and smallest DECT handset in the portfolio; it satisfies the most stringent requirements in terms of high end functionality and design and suits perfectly to various jobs.

From the high-quality handset with silver front side, to the large 2.4” TFT color display with modern user interface, this handset looks exquisite. It offers one of the largest display in the handset-portfolio; approx. 33% larger display size compared to the 1,8” previous display. The large display is ideal for easy readability by almost identically housing dimensions.

As well as great style, it offers optimum functionality, with excellent voice quality, Bluetooth Interface and a 3.5mm headset jack. The OpenScape DECT Phone SL6 is the successor of OpenScape DECT Phone SL5.
