If this function has been configured (contact System Support), you can turn up to four relays on and off to control different facilities (such as a door opener).
Depending on how they are programmed, you can switch the relays on and off or switch them on and have them switched off automatically after a timeout. 

Special features must be taken into consideration if your telephone operates with HiPath AllServe (system networking via PC network) !

Select and confirm. 

Enter the code for "on" or "off". 

Enter the relay.
