First, press the OK button in the upper left to wake up the main interface.

Then, remember to check the battery capacity at the top right of the screen.

Change the battery promptly if it is powered off and press the OK button to sign in according to the prompt when hearing the instruction.

The word Successful Signature will be displayed on the screen.

After hearing the question submitted by system software, you need to send the answer by pressing the button.

For instance, if you want to press number 17, you have to press number 1 first and then press number 7, and at last confirm the answer and submit it by the green button.

Please check carefully before submission.

The answer is unchangeable after you submit it successfully.

If you find that you push the wrong button, you can use the red button C to delete numbers bit by bit, then send the right answer.

For example, you send the number 1708 instead of number 1718.

At this time, you need to press the red button C for 2 times to remove number 0 and number 8.

Then, put number 1 and number 8 in it and submit the answer by pushing the green one.

More importantly, keep an eye on remaining time on the screen.

Once over the time, you no longer can send the answer.

These are the usages of Intelligent Training Competition Response System.
