The electronic circuits within this instrument are susceptible to
electro-static discharge (ESD) damage. Use ESD precautions to
avoid damage.
• Use only a table top with a grounded conducting surface.
• Wear a grounded, static-discharging wrist strap.
4. Pull the detector board straight out of the optics block.
5. Remove the new detector board from service kit. See chart:
