  1. Getting into the Self Diagnostic mode
    Press [Start TEST] button first, followed by pressing the [Auto Start] button. Hold onto the button and do not release the button. You will notice that all the indicators all lighted up. Hold the buttons until all the 4 indicators lights are off. Then you can release both the buttons.
  1. Begin the diagnostic
    You will notice that the green indicator <Pwr> will be permanently lighted up instead of its usual blinking. This means that the tester has successfully boot into a special operating mode.

    The 4 indicators <Sound> <Auto Start> <PASS> <FAIL> should blinking continuously. This also means that the LED indicators are working.

    This means that you have successfully booted into the self diagnostic mode.
  1. Stage 1: Testing the touch buttons
    You will notice the 4 blinking LED indicators. You will get to touch and have the buttons tested here.

    For each button that you pressed, a corresponding LED indicator will stop its blinking. From this response, we will know that the touch button is working well. There should also be a beep sound. This means that the buzzer is working.

    [Button name] -> <Corresponding LED indicator>
    [Sound] -> <Sound>
    [Auto Start] -> <Auto Start>
    [Start TEST] -> <PASS>
    [Learn] -> <FAIL>

    Once all the 4 buttons are pressed and tested to be ok, you will hear a double beep from the buzzer with a quick blink from all the light indicator. This means that the test from this stage is completed successfully. You will then be guided into the 2nd stage.

    An option test can be done on the external interface port. The PASS and FAIL output will be switch on alternating. When the input TEST signal is trigger, both PASS and FAIL output will be permanently turned on.
  1. Stage 2: Ensure all the ports are not connected
    At this stage, you may see that the 2 indicators <PASS> & <FAIL> blinking together.

    If you are seeing this two LED indicators blinking alternating instead, it means that you have passed the test for this stage 2. You can ignore the following stage no. 2 procedure and proceed directly to stage 3 testing.

    To pass the test for this stage is simple. Just ensure that the 64 ports on this tester is not connected. This is to ensure that there are no internal short circuiting of the ports.

    You can press the [Start TEST] button to display the current state of the port connectivity. It can help you see any short ports that is preventing you from proceeding to the next stage.

    Once you have your ports disconnected, you will be into the next stage no. 3.
  1. Stage 3: Testing each individual port connectivity
    At this stage, you will see that the 2 indicators <PASS> & <FAIL> blinking alternating.

    Your task at this stage is short a pair of ports at any one time. All the 64 ports (from A1…A8 to H8) has to be shorted. Every time a pair of pins is shorted, you will hear a short beep and a blink from the <Sound> indicator.

    Tips: You can use the 4pos connector plug to help you short and test the ports. Connect the first and last pins of this 4pos connector with a short piece of wire. You can use this plug to short through all the ports.

    You can press the [Start TEST] button to display a list which shows you which ports has already been tested, and which has not.

    Continue to finish up shorting all the ports. When all the ports are tested and are in working condition, the cable tester will do a 3 sets of beep and LED indicators flashing. This indicates that all the ports are working properly, and that the whole self-diagnostic checks are completed successfully.

    The cable tester will then proceed to reset back to the normal cable testing mode.
