I run 4 MT-D phones by AVM at the Fritz! Box 7270. Before I installed the DECT repeater of HAMA, calls me regularly brought to Verzweifung because talks broke off suddenly, the spoken or heard was incomprehensible. Every step of more than 7 meters away from the base station, resulting in a telephone technical problem because the measured my needs low transmitting power of the base station. Since I have the Hama-DECT repeater installed, work my phones without limitation. I telephone from every room of the house. On the terrace, in the garden - 40 meters away from home, anywhere there is best receiving. The installtion of HAMA repeater is as simple as simple can not. I would highly recommend this repeater without limitation.
