How to activate my jQuery slider automatically?

I have a jquery slider as built-in part of the theme I am using (Rusty Metal Plate of Azure). The slider has left and right arrows which work perfectly. I would like to add an automatic timer to the slider so that it slides or activates every xx number of seconds. I’m guessing this can be accomplished with a couple lines of code, but I’m still a beginner. Can anyone help? I’ve included the slider code below:

<script type="text/javascript">
var $jx = jQuery.noConflict();
$jx(function() {
 $jx(".mygallery").jCarouselLite({
 btnNext: ".nextb",
        btnPrev: ".prevb",
		visible: 1,
		easing: "easeout",
	    speed: 500
    });

});
</script>

<div id="slidearea">

<div id="gallerycover">
<div class="mygallery">

	<ul>
			<?php
			$ax_featured_category = get_option('ax_featured_category');
			$ax_featured_number = get_option('ax_featured_number');
			$my_query = new WP_Query('category_name='.$ax_featured_category.'&showposts='.$ax_featured_number.'');

			while ($my_query->have_posts()) : $my_query->the_post();$do_not_duplicate = $post->ID;
			?>
 <li>
<div class="mytext">

<?php $values = get_post_custom_values("feature_image");
	echo get_thumbpic('feature_image_value','350','200','slidim',90);
	?>
<?php the_excerpt(); ?> 

</div>
 </li>
			<?php endwhile; ?>
     </ul>

    <div class="clear"></div>  

</div>

</div>

   <a href="#" class="prevb"></a>
   <a href="#" class="nextb"></a>  

</div>
