Settings

Install the accessibility module as detailed in the installation instructions and go to administer > settings > accessibility. There are four sets of options that you can configure to suit your needs.

Enable Accessibility
Override Pages
Override Settings
Additional Settings

Enable Accessibility: You must select this to actually invoke the module. Checking the box mean that the module will start detecting the device and set headers, themes and content accordingly
Override Pages: This option allows pages to be sent as text/html. This is particularly useful for the admin pages and any other parts of the site that may include any JavaScript or DHTML that doesn't work when the content type is set to application/xhtml+xml. For users browsing with hand-held devices these pages are forbidden and relevant error messages are sent. See roles for more details
Override Settings: Enable Media Type Override is for User 1 only. This option enables the administrator to test the site or themes for other devices. A good way to check if this module is working as expected; Override xHTML mime type enables the administrator to change the content type of the whole site to text/html. This option is here because of the extreme nature of the application/xhtml+xml content type. Note that mobile users content will still be sent using the detected content type; Try to correct HTML is based on the htmlcorrector module and attempts to close HTML tags in accordance with XHTML standards.
Additional Settings: You can break down content into smaller pieces using a function based on the paging.module. You will need ensure that this input format is allowed. Currently I use <br class="mobi">. Also check that this input doesn't break your HTML code *; The final setting allows you to "lock" the themes available. Handy if you don't want to modify multiple themes. Check this box if you only want to use the theme that is found in the web theme directory. Mobile devices are locked to their default themes and this setting is currently fixed
