Firmware updates

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.
