=== RF Shield Maintenance ===
The metal RF shield covering the main chips requires special attention:

'''Removal:''' Twist the metal tabs with needle-nose pliers - work slowly to avoid breaking tabs. Later models use clips that can be gently pried open.

'''Cleaning:''' Light surface rust on the RF shield is common and doesn't affect function. For heavy corrosion:
# Sand lightly with 400-grit sandpaper
# Clean with isopropyl alcohol
# Apply thin coat of clear acrylic spray for protection (optional)

'''Reinstallation:''' Bend tabs back carefully - they tolerate 2-3 bend cycles before metal fatigue causes breakage. Ensure shield sits flat for proper grounding.
