CLRMOS1 allows you to clear the data in CMOS. e data in CMOS includes
system setup information such as system password, date, time, and system setup
parameters. ere are two ways for you to clear and reset the system parameters
to the default setup. Please turn o the computer and unplug the power cord, then
you may either short the solder points on CLRMOS1 by using metal material,
e.g., a paper clip for 3 seconds; or you may use a jumper cap to short the pin on
CLRMOS1 for 3 seconds. Please remember to remove the paper clip or the jumper
cap aer clearing the CMOS.
2-pin Jumper
*e jumper cap is not provided.
If you clear the CMOS, the case open may be detected. Please adjust the BIOS option
