STAR Tester: Use

Power up the tester. A display check begins with a flashing "88". The tester is ready to be activated when "00" is displayed.

When instructed, press the push button at the front of the tester to begin the appropriate test. The button will latch down, and the display will change to ":00". The colon MUST be displayed with the zeros to receive codes.

Record codes as they are displayed. The test is exited by unlatching the button.

Go to Step 3.0.
