How do I Add and Delete Words in the Word Prediction Dictionary in my ECO?
In the Word Prediction Menu you can modify the PRC Dictionary.

Add a PRC Word
This option allows you to add words to the PRC Dictionary.
Activate Add a Word and type in the root word of the word you want to add. (A root word has no endings to it, such as 'es', 'ing', etc.) For example, enter the word "abominate".
The display asks you to enter a word with similar word endings (that is, a word used the same way in sentences and with the same kind of endings as the word you entered). Type in a similar word. For this example, type "Terminate". "Terminate" shows in your Word Prediction window so you can select it. Activate OK.
You see a box containing the word you want to add with all its endings. If most of the endings are correct for the way you want to use your word, activate YES. The new word is entered into the dictionary. If the endings aren't right, activate NO, type in a new "similar word" and try again.
*At this time you cannot make changes to the WordQ Dictionary.
Delete a Word
This allows you to delete a word from the dictionary.
Activate Delete a Word. Type in the word you want to delete. Select the word from the Word Prediction Window. Activate OK. The word is deleted.
Reviewing Words in the Dictionary
You can review words in the dictionary. Perhaps you want to check out the words that begin with specific letters or maybe you just want to see the whole dictionary. You can review the dictionary by viewing it on your display screen, by seeing it on the display and also hearing it spoken, or by seeing it on a computer monitor or printing it out.
STEP or AUTO are options for how you can go through the pages of words. STEP means that you must activate a switch or touch the screen to move from page to page. AUTO means that your device will automatically change pages for you after the pre-set amount of "looking" time has passed.
*You can activate the Previous Items, More Items or the Cancel keys at any time whether you are using Step or Auto.
Review to Display
This sends the dictionary to the display screen. When you select this option your device tells you to enter the start letters of the words you want to review. If you want to review all the words that begin with a certain letter(s), just type that letter and activate OK. If you want to see more specific words, type in more letters. For example, if you type in "chu" you will see all the words that begin with "chu".
If you want to look at the entire dictionary, do not type in anything. Just activate OK.
Review to Display and Speaker
This works the same way as Review to Display except that your device will speak the entries on each page.
Review to File
This allows you to save the dictionary review in a file on a USB drive or on the ECO's hard drive. If you have the optional internal computer, you can open the file in Word Pad on your ECO. If you do not have the internal computer, you should save a review to your USB flash drive. Then you can transfer it to your external computer and open it in a word processing program. Remember to set the correct options in the OUTPUT MENU.
Load PRC Default Dictionary
When you receive your device, the default PRC Dictionary is already loaded into it. You can add words to, and delete words from, this dictionary.
If you make many changes to the dictionary and then decide you want the original PRC dictionary loaded back into your device, you can use the Load Default PRC Dictionary option. When you load the original dictionary back into your device, all of the changes you have made to your current dictionary will be lost.
*If you want to save your current PRC dictionary, perform an MTI and select the Save Entire Device option. See Using the Transfer Memory Menu chapter.
*At this time you cannot make changes to the WordQ dictionary.
