For accessing the built-in 2-way speakerphone. When you press [ Shift ] and then [ Speaker ] (your voice terminal must be on-hook, and it must be set for the Speakerphone feature), you hear a set of tones as the speakerphone performs an acoustic test of the environment. When the tones stop, your speakerphone has finished adjusting itself for optimal performance and is ready for use.

The light changes to steady green when the voice terminal is able to communicate with the PBX, and then goes off after a short period of time. After the voice terminal is powered up, you can press [ Test ] to test the lights and the display on your voice terminal.

●When used with [ Hold ] , you can select a personalized ring from among eight available patterns.

●When used with [ Speaker ] , you can perform an acoustic test of the environment and adjust the speakerphone to the surrounding acoustic environment for optimal performance (for the built-in speakerphone option only).
