Handle the Ultrasound Applicator(s) with Care

• DO NOT drop the sound head on hard surfaces.
• DO NOT allow the sound head to reach maximum temperatures repeatedly.
• DO NOT cool an overheated sound head with ice water or ice packs.
• All of these conditions are likely to damage the sound head crystal.
• Damage resulting from these conditions is not covered under the warranty.
