Level 2: Circuit board or standard parts replacement 

Firmware updates 

Firmware updates for the monitor are available at 

support.hp.com

. If no firmware is posted, the monitor 

does not need a firmware update. 

Before returning the repaired product to the customer 

Perform an AC leakage current check on exposed metallic parts to be sure the product is safe to 
operate without the potential of electrical shock. Do not use a line isolation transformer during this 
check. 

Measurements that are not within specified limits present a possible shock hazard. You must check and 
repair the product before returning it to the customer.
