part number when ordering replacements. Do not attempt to use any other
replacement part for this procedure.
CAUTION
•
Perform all electrical replacements in a suitably clean and dry environment. Clean
away all surface contaminants before opening the electrical circuit enclosure.
•
Protect the exposed circuitry from electrostatic discharge, as this may destroy or
disable components. Wear a ground-strap while working on exposed circuitry.
•
Dispose of electrical circuit waste in accordance with local laws and regulations.
WARNING
•
Supercapacitors retain charge for a significant period. A risk of electrical shock exists
while the supercapacitors are charged up. A discharge could cause either personal
injury or damage to equipment.
•
Be sure that the unit under repair has been disconnected from its power source for 5
minutes. Do not attempt to replace until the supercapacitors have discharged
completely.
