the greater of the amount actually paid by customer for the product or five

dollars (US$5.00). The foregoing limitations, exclusions and disclaimers

shall apply to the maximum extent permitted by applicable law, even if any

remedy fails of its essential purpose.

Safety of high-voltage evaluation products

 — The non-insulated high

voltages that are present when operating this product, constitute a risk of

electric shock, personal injury, death and/or ignition of fire. This product is

intended for evaluation purposes only. It shall be operated in a designated

test area by personnel that is qualified according to local requirements

and labor laws to work with non-insulated mains voltages and high-voltage

circuits. The product does not comply with IEC 60950 based national or

regional safety standards. NXP Semiconductors does not accept any liability

for damages incurred due to inappropriate use of this product or related to

non-insulated high voltages. Any use of this product is at customer’s own

risk and liability. The customer shall fully indemnify and hold harmless NXP

Semiconductors from any liability, damages and claims resulting from the
