This watch is very cool. However the manual does not represent the watch I have. Therefore I'm not able to use the Teledata function because I don't have a "D" button. The "Light" button is located where the "D" button should be. I have been researching this for two days. Pulling manuals from the Casio website and othe sources. The picture you provide shows the watch I have but the manual shows a completely different watch. I have used model number and module number and get the same results. So although the watch looks real neat I cant input Teledata without a "D" button.<a data-hook="product-link-linked" class="a-link-normal" href="/Mens-Casio-DBC30-1/dp/B001YPAAY6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Mens Casio DBC30-1</a>
