I was rooting around in our storage shed and found a Ray Jefferson L-400 and I don't recall where I got it from. <br /><br />The L-400 isn't one of the common ones by Ray Jeffereson. The L-100 and PL-99 are much better known. The L-400 has 200 waypoint storage capability.<br /><br />This thing has the owner manual with it, and I've reviewed it thoroughly. One problem is still there, and I need help with it to get this thing working.<br /><br />The set does come on like it should, and automatically finds our GRI, etc. <br /><br />The part that's weird is the keypad area. There are two distinct groupings of the touch keys. <br /><br />One groups is (In addition to being numeric):<br /><br />L/L, WPT, TDs, TTG/COG<br /><br />The other group is (in addition to being numeric):<br /><br />L/L, WPT, TDs, STATUS<br /><br />The remaining keys are (in addition to being numeric): <br /><br />HOME, FUNC, SAVE, CHANGE, ROUTE, PREV, NEXT<br /><br />I need some help figuring out what the two grouped sections are functionally for. <br /><br />At first, I thought it might be that one group handled waypoint #s 01-99, and the second dealt with waypoint #s 100-199. However, there are functional differences between the upper and lower key pad groups. So, I now doubt that the split waypoint sections are the reason for the difference.
