Introduction

Thank you for purchasing the LISST-HOLO Submersible Digital Holographic Camera!

The intent with this introduction is to get you started using the LISST-

HOLO as quickly as possible. Sequoia’s goal with the

LISST-HOLO is to make the user interface so friendly that no manual would be required for normal operation, except as a first-
time introduction to the instrument

The LISST-HOLO was shipped to you in a Pelican case with custom foam padding.  Included in the shipping box are the LISST-
HOLO,  clamps,  stands,  External  Memory  Module  with  USB  cable,  Ethernet  cable,  Wireless  Router,  Serial  Cable  with  Power
Supply, and a spare 5-pin cable for connecting the LISST-HOLO to alternate power source such as a CTD.

Sequoia  Scientific,  Inc.  is  pleased  that  you  have  chosen  one  of  our  products.  Thank  you!  We  strive  to  make  our  instruments
rugged, reliable, and simple to operate.  If you should have any difficulties or questions regarding this product, please feel free to
