Look for parts which, though functioning, show obvious signs of
deterioration. Point them out to the customer and recommend their
replacement.
6.
Check the line cords for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
7.
Check the antenna terminals, metal trim, "metallized" knobs,
screws, and all other exposed metal parts for AC leakage. Check
leakage as described in "Leakage Test".
