Define it in Settings Code lists Locations. Geographical group for routers. You can use it for cities or town districts, counties etc. It helps you with schematic displaying of routers. If you administrate more cities or villages, you can use the names of specific cities and villages. If you administrate only a few cities, you can use names of city districts. If your network is very extensive, it is more suitable to select distribution of locations into districts or regions. With this distribution you will significantly make more clear displaying of routers in individual system screens. It is also possible to filter records and client according to this division. For example: bulk email and SMS.
