        • Connect the handset of the telephone under test to CRY6151B DUT MIC (headset) / HEADPHONE 1 (receiver)

        • CRY6151B makes the mouth simulator sound through MOUTH1 port-> DUT MIC interface microphone to acquire sounds -> input into CRY6151B for analysis

        • CRY6151B uses the HEADPHONE 1 to output audio and make the receiver under test sound -> the ear simulator microphone to acquire sounds -> input into CRY6151B for analysis
