Precautions when magnetizing
• Reversing sides q and w of the magnetizing magnet reverses magnetic polarity, result-
ing in incorrect sensor operation. Be sure to use the correct side of the magnet when
magnetizing or demagnetizing.
Precautions concerning the magnet
• The magnetism of the magnet is extremely strong, so keep watches, magnetic cards and
other such items well away from it. Placing watches or magnetic cards near the magnet
may damage them, resulting in faulty operation.
• The magnet will be needed to magnetize the tire again at a later date, so be sure to store
it in a safe place. When storing, follow the precautions below.
— Do not store in direct sunlight or where temperatures may become high.
— Do not store in the trunk of your car as the trunk can become very hot during the
summer. The magnet may also influence the sensor unit installed in the trunk.
