TA-23 Handset accessory setting

Toggle Button in the TFIE-1 station

When "Accessory" is set to "Handset" the station is by default in loudspeaking mode, i.e. the audio is routed to the speaker and microphone of the front panel of the TFIE station. Audio is also routed to the handset speaker, but the handset microphone is disabled.
When a call is received, handset mode is activated by pressing the PTT button in the handset. The audio will then be routed to the handset, and the loudspeaker and the microphone in the front panel is muted.
When the TFIE station returns to idle, e.g. when a call is ended, the station will automatically return to loudspeaking mode.
In stations with Toggle button (TFIE-1 only), one can also use this button to activate the handset. The button lets you toggle between loudspeaking and handset mode. The LED in the toggle button shows the status:
- Green LED = Loudspeaking mode
- Red LED = Handset mode

In the Audio Inputs section set the "Internal Microphone" to I/O Pin A->D Switch (until call-end), and select Pin number for the PTT signal. See also Audio_Settings_(Devices)#Audio_Inputs.
