•  Depending on the type of system concerned, registration may require one or more additional operations 
on the system. 
During registration phase, to improve security and optimize registration in a multi-system environment, the 
handset enforces a minimum signal strength level to accept to register to a base station. To achieve the 
conditions, it is recommended to perform registration in a place where a base station is in direct visibility 
within a 20 m range. If base station is not visible the range shall be lowered. 
During registration phase in a multi-system environment, all systems are scanned without priority. The 
system is selected when the signal strength is above a certain level and registration matches. 
7.3  Selecting your telephone system  
Your telephone can be programmed to function on 4 different DECT systems (Alcatel-Lucent Enterprise or 
GAP). 
The selection is retained even after switching the telephone on/off. The selection of a specific system 
forces operation on a specific system. This selection must be changed if one wishes to change system. 
Selecting 'Auto. select' enables the telephone to connect automatically when it enters a system coverage 
zone. If the systems programmed in the telephone have common coverage zones, the telephone selects 
the first system found.
