Step 7. On the same line as "Replace", look for "With" and "Text Only", and then "Formatted Text"

Step 8. Click the circle next to "Text Only"

Step 9. Go back and click "Replace", then type a simplified version of your symbol

Advice
- Go to "Tools" and then "AutoCorrect Options …" instead of opening "Symbols" in Word 2003.
- If Microsoft Word 2010 go to Insert Symbol, Select UI Symbol, and scroll until you find the triangle with the exclamation point inside. Done.
