Unpacking

2.1

UNPACKING

The packaging is designed for typical shipping and handling.  Upon receipt of shipment, check
for signs of damage before opening and report all damage to the carrier.  All shipments made
from DTS are the customer's responsibility once they leave our premises.

Before installation it is suggested that a complete inventory be taken to minimize problems or
questions during installation.  Additionally, save all packing material until installation is complete
in the unlikely event that a component(s) requires return to the factory.  Use the packing slip
that came with your unit to verify received inventory.

The following is a sample packing list for a single system.

Typical DTS Pro Audio Equipment Package consists of:

•

  CAE-4 Professional Encoder

•

 CAD-4 

Decoder

•

  E175-DVD Timecode Controller

•

  E175-DVD (1/4” Jack) to Encoder ( XLR) Cable assembly

•

  E175-DVD power adapter

•

  DTS Software suite including the DTS Record Panal and bitstream tools software on

CD-ROM

•

  Record Panel software on CD-ROM

•

  CAE-4 Encoder System Manual

•

  Spec Sheets for the CAE-4 Encoder and CAD-4 Decoder
