The combination of the sixteen-character display and the six function keys on the Forum Phone 310   

facilitate access to many of the most commonly used Forum 300 system features.  This section of the 

guide provides detailed instructions on how to use the Forum Phone 310  . 

  

Note :  At installation, extension 11 is set as the default administration phone and it’s best to install 

an Operafone Executive at extension 11. 

 

Incoming calls to the Forum Phone 310  are indicated in several ways - 

− 

The tone caller sounds 

− 

The LED alongside the 

SPEAKER key flashes 

 

− 

The incoming call is shown on the display 

 

 

 

 
 

As well as normal dialling, i.e. entering digits once the line has been selected, the 
Forum Phone 310  allows the digits to be pre -dialled before the line is accessed.  

This allows the user to check the number before going off-hook by lifting the 
handset or pressing the 

SPEAKER key.
