1.11,1 Clear CMOS Jumper: CLRTC1

There is a CMOS RAM onboard that has a power supply from an external battery to keep the data of

system configuration.

For normal state (default), the jumper is set on pin location 1 and 2.

To clear the CMOS, set the jumper to pin location 2 and 3 for at least 30 seconds while the system is off.

1. You can clear CMOS by shorting pin 2-3 for at least 30 seconds (while the system is

OFF), then place the jumper back to pin 1-2 for normal operation.

2. It is recommended to remove all power connections from the power supply to the

motherboard while clearing the CMOS.

3. Avoid clearing the CMOS while the system is ON; this will damage the motherboard.
