bodily injury or property damage resulting from the misuse of its products.
Keep these guidelines in mind and always use your own good judgment when controlling volume:
• You should limit prolonged exposure to volumes that exceed 85 decibels(dB).
• High volume in an automobile can hinder your ability to safely operate a vehicle.
• You are responsible for knowing the local laws governing acceptable mobile volume levels.
