The installation was a breeze: enable base station into registration mode for DECT phones, stuck Repeater into the outlet, wait until the LED flashes green to confirm that the repeater has found the base. Then completed the basic registration mode automatically, bringing Repeater from the wall outlet and to the installation site, plug in again - it automatically searches the base and place them after a few seconds. Done. The whole operation lasted 5 minutes.
However, the DECT ECO mode is mutually exclusive (avoiding unnecessary radiation exposure) and Repeater mode - logical.
The repeater is surprisingly small ... I had not seen in the technical data sheet on the dimensions: 12.7 x 11.9 cm.
