Unpacking before installation
All shipping containers have been specially designed to protect their contents and special
care has been taken to prevent damage under normal shipping conditions. Mishandling
should be evident upon inspection of the shipping container. If shipping damage is found
after visual inspection, take care not to destroy the evidence. If necessary, document the
damage with photographs and contact the carrier immediately.

is recommended to save all original packing cartons and crates to protect your amplifier
from damage should you wish to store it or ship it for after-sales service.
