Customize this Documentation - My_Notes

My_Notes are easy to incorporate directly into the pages of this manual. They can be used to clarify content, add additional information, or document your custom settings, operational tactics or procedures. My_Notes are page specific and display at the bottom of the desired page under the "My_Notes" heading. No programming is required - it is as simple as saving a file with your notes.

Creating My_Notes

My_Notes can be written in HTML or plain text. HTML allows for more flexible formatting and inclusion of images or links to other web pages.

To add a My_Note, create an HTML or text file containing the note and save it in the VideoRay\My_Notes\ folder, which can be found in the computer account user's documents folder (Documents\ for Windows 7, or My Documents\ for Windows XP).

The file should be named the same as the page in which you want the note to appear, with a "my_" prefix (without the quotes). For example, if you want a My_Note to appear at the bottom of this page, the name of the file to create is: my_custom_my_notes.html. The name of the page being viewed can be found in the address bar of the browser being used to display this documentation.

Even if you are using a text file, the file name must end with the ".html" extension.

All My_Notes files are processed as HTML, so if you are using a plain text file, you will need to add "<pre>" (without the quotes) at the beginning of the file and "</pre>" (without the quotes) at the end of the file if you want to preserve the layout. The "<pre>" and "</pre>" will not show up in the display.

When using HTML, the My_Notes folder serves as the root for relative links. An images folder is included for you to store images. You may add other folders or files as desired.

Viewing My_Notes

When you reload the page, your My_Note will appear - there is nothing else to install or configure. A sample My_Note file has been included to display the My_Note below. You can use this file as a model for creating your own My_Notes.

Updating My_Notes

To update a My_Note, simply edit and re-save the My_Note file.

Removing My_Notes

My_Notes can be removed by deleting or renaming the My_Note file.

Sizing My_Notes Display (Optional)

The default vertical size for My_Notes is set to 200 pixels, which is used for the sample My_Note below. Due to browser limitations, My-Notes do not size dynamically. This means that a long My_Note may display a scroll bar in order to view the whole My-Note. You can adjust the size to eliminate the need for the scroll bar. To set the size of a My_Note, you need to edit the file named "my_notes_size_table.js" in the My_Notes\ folder (location defined above). The file contains one line for each page of this document using the following format:

    window.page_name = size_in_pixels;

Find the line for the page that includes the My_Note you want to resize and replace the value of size_in_pixels with the desired size in pixels. The page names are listed alphabetically. Example line from the "my_notes_size_table.js" file for this page:

    window.custom_my_notes = 200;

Note that ".html" in not included in the page name, and the line must end with a ";" Also, the optimum size required is dependent upon the size and aspect ratio of the browser window.

Safety First

Operating electrical devices in and near the water can be dangerous. There is always a risk of drowning or electrocution in such an environment. Reduce these risks by using common sense and observing safety regulations and recommended safe practices including the following:

• Never handle power cords while in contact with water or allow power cord connectors or the control panel to enter the water. The only components that can safely be placed in water are the submersible, any onboard accessories and tether, and only after making sure the connections are secure.

• Always test the safety components, such as GFCI switches and interlock devices, before beginning operations. Follow the procedures described in this manual for.

• Have proper safety equipment, such as PFDs (Personal Flotation Devices), on hand and make sure you know how to use them before you need them.

• Keep fingers, hair, loose clothing and other objects away from VideoRay's propellers and other pinch points.

• Monitor weather and sea conditions and heed any warnings or alerts.

• Be aware of and follow any legal ordinances or regulations in your area regarding operation of vessels and underwater equipment in the water.

The Cygnus Ultrasonic Thickness Gauge has pinch points. Caution should be used when handling the Cygnus Ultrasonic Thickness Gauge.

Before setting up for or commencing any dive, it is a good practice to make sure there are no hazards to people or the equipment on land or in the water. If there are other people in the water nearby, you should advise them that you are going to be operating the ROV. As the owner/operator, it is your responsibility to ensure the safety of those around you as well as that of the equipment and nearby property.

How Safe Is Safe Enough?

Addressing all aspects of safety while working in a water environment is beyond the scope of this documentation. VideoRay encourages you to participate in safety training appropriate for your industry and applications, including such topics as vessel operations, first aid, survival and other relevant topics.

Introduction to the System Components

Unpack the system and familiarize yourself with the components.

The Cygnus Ultrasonic Thickness Gauge includes a gauge, skid plate, and Swing Arm Module. The Thickness Gauge kit also includes other miscellaneous hardware.

Additional Items

Additional items may be supplied with your system including tools, spare parts and other items. If included, these items are described in other sections of this documentation.

Some items shown may be optional and not included with your configuration.

Pre-Dive Preparations

The Cygnus Ultrasonic Thickness Gauge requires installation before use, follow the steps below to prepare the Thickness Gauge for use:

1. For the first time only, install the Cygnus Ultrasonic Thickness Gauge software.

2. Mount the Thickness Gauge onto the ROV.

3. Start the Thickness Gauge software.

4. Check to make sure all components are secured tightly and perform a functions test to ensure the Cygnus Ultrasonic Thickness Gauge is working properly before diving.

Good Advice

The time to catch small problems before they become big problems is during the pre-dive inspection.

Dive Operations

Prior to launching the VideoRay, check the buoyancy and adjust the ballast weights as necessary to achieve the desired buoyancy and trim.

When diving with the Cygnus Ultrasonic Thickness Gauge, the Pro 4 Hand Controller is used to adjust the Swing Arm Module angle up or down.

Practice Makes Perfect

Developing the skills to operate your Cygnus Ultrasonic Thickness Gauge like an expert may take some time. Practicing on a regular basis is highly recommended.

Post-Dive Operations

Make sure to clean and rinse all equipment in fresh water after use. Allow the components to dry before storage. For optimal results, remove the Swing Arm Module before attempting to clean the equipment.
