The NurseCall Main Unit is the control panel of a radio system which is easy to install and can be used for facilities such as nursing homes or for assisted living. For residents such as dementia patients, who have physical and/or mental disabilities but would like to move around freely, the NurseCall Main Unit is well-suited in combination with a pendant transmitter or a wall transmitter. Unlike wired solutions, there is little effort required to install the NurseCall Main Unit. This is beneficial in existing set-ups and when changing or expanding old systems.
