g) TEST FUNCTION

This is the test function.

.Fan operation check only

When the FAN DRIVE is changed from AUTO to

MANUAL, and ENTER is pressed, the DRIVE DATA

indication changes to cyan. In this setup, the drive

drive register value is changed, the pulse width of the

PWM signal in the fan voltage control PWM circuit is

changed accordingly.

Fans can be checked whether they operate normally or

not by comparing the register value and the actual

drive voltage, and by comparing the actual drive

voltage and the actual operations of the fans.

Variable range of the drive register value :

00000 to 16383

.Blue only

When Blue only is selected, all of the R, G and B colors

become the blue data.
