Recommended Red LED Optical Power
In order to optimize the tracking performance and minimize the LED power consumption, PixArt recommends the LED optical power conform
with the table listed below. LED optical power is measured through the base plate opening of the mouse casing with the LED set to
continuous mode. Recommend using ADCMT power meter 8230E to measure the LED optical power. The sequence to set LED to
continuous mode is as followed.
Write address 0x09 = 0x5A; to disable Write Protect
Write address 0x5B = 0x63; to set LED to continuous mode
