The Gigaset Repeater is a kind of transmitting station that you set up some distance away from your base telephone. This doubles your freedom of movement. Within the enlarged transmission area you can receive calls and make internal and external calls - while moving around freely at the same time. The area of use of the cordless telephones can be maximised by using up to 6 repeaters in a circle around the base station. Note: The Gigaset Repeater is also compatible to the whole range of Gigaset 4000 (except A100, A200), 3000, 2000 and all models 'C' class upwards cordless phones.
