|The Olycom M1060 is a 1 trunk, 6 extension telephone system.
From the photo with the terminal cover removed, you can see the power lead to the left, then 6 terminal pairs for the 6 extensions, and lastly a single pair for the trunk line.
The system has built in 'Greensleeves' music on hold for external held calls, and a 3.5mm socket to which you can connect an alternative hold audio source at the extreme right of the terminals.
The codes below are supposed to reset your system to UK default. Only use if nothing else works. They are not guaranteed to work.
