1. General 
A repeater (R-168) is used when you need to extend the range of your cordless DECT telephone to include areas where reception was previously not available.
All the usual mobile unit function are supported by the base station in this extended radio range.
The repeater and base have wireless connections with each other, just as the repeater and handset have wireless connections. Signals are exchanged without the user hearing or noticing the difference.
The radio communication distance between handset and base station of DECT system is around 200~300 meter in line of sight . The radio coverage of base station can be extended by setting up a repeater at appropriate position.

2. System with Multiple Repeaters
Up to 6 repeaters can be registered at a base station. The number of mobile units to be operated only depends on the type of the base installed.

All repeaters must be installed within the base stations coverage area. It is not possible to install repeaters in series. 

The repeater can be used to extend the coverage area in all directions, including up and down (e.g. to cover several floors in a building )

If the repeaters are placed correctly (overlapping the coverage of the base station), you can go from one area (cell) to the other while speaking on the mobile unit.

The mobile unit will automatically switch from cell to cell without this being noticed during the telephone call.

Before the repeater is installed, it must be registered to the base station.
The repeater can be registered to a base station in 2 ways , automatic or manual registration.
