To service personnel
Preparing Jamo products for shipment
If possible, use the original packing material for any shipping. Otherwise, repack the product
using:
• A reinforced cardboard box, strong enough to carry the weight of the product.
• At least 6 cm / 2.36 inches of shock-absorbing material around the product.
• Nonabrasive dust-free material for the other parts.
• Nonabrasive wrapping for the product. (Dust and dirt cover)
• Repack the product in a manner to ensure that it cannot shift in the box during transport.
Never ship products, like speakers and subwoofers, with spikes mounded. Spikes can penetrate
the cardboard and other packing material causing serious damage.
