as before it was observed in audio test if any device port is not connected , then without handset all test was going on without the pcba sn due to this was leading to high ct at audio machine stage now we have update the sequence of audio machine stage , if any device port will not not connected then no item test will be performed and it will exist all the test . hence by doing this we have saved time around 20-25 second in case of power off handset 02/2023

Separation of ENC and ANC Testing to Improve Audio Test Efficiency in T51 Model

In T51 model, a new feature called ANC test was introduced, which is performed through the Audio Test Machine. Initially, ENC and ANC tests were conducted together on the same machine. During checking, it was observed that: ENC test switching time was very high Due to combined testing (ENC + ANC), overall cycle time increased Audio test process became slow Line efficiency was reduced It was decided to separate ENC and ANC testing to optimize the process. New setup: 2 machines assigned for Left ENC + ANC 2 machines assigned for Right ENC + ANC ENC and ANC are now tested separately instead of combined This reduced unnecessary switching time during testing. 01/2026
