Dial Switch Function Description

Default Advanced Audio Testing

1. Call Testing
   
   When enabled, the test box connects to the prototype phone's audio, allowing call testing to be performed.

2. Call Microphone Loopback Testing
   
   When enabled, speaking into the prototype's microphone sends audio to the test box, which then relays it back to the prototype, and the prototype's speaker plays the audio.

   • ON: The microphone sound is output from the prototype's speaker.
   • OFF: The microphone sound is output from the test box's speaker.

3. Quick Testing
   
   When enabled, upon connecting to the prototype, the test box triggers the prototype to enter quick test mode. In this mode, the prototype activates its speakerphone function. Speaking into the prototype's microphone results in the sound being played through the speaker. Pressing a key on the prototype plays a key tone. Note: This feature requires the prototype to be on ac690x_sdk2011 or higher. Users must add an indicator light to the prototype to signal entry into this mode, depending on the prototype's configuration.

4. Frequency Offset Testing
   
   When enabled, connecting to the prototype initiates frequency offset testing.

5. Automatic Frequency Offset Correction
   
   When enabled, automatic correction is performed during the frequency offset testing process.
