PBX access code
If you’re connected to a switchboard, you might need to enter an access 
code (e.g. 9) before you dial a number. Your BT8610 can store an access 
code which is automatically dialled before each number. We cannot 
guarantee that all the BT8610 features will work when connected to a PBX.

 to highlight PBX code, press Select. Enter the number you 
want (maximum four digits). If you wish to stop using a PBX access code, 
go into the PBX code menu and delete all the digits by selecting 
Clear, 
then select 
Save.
