First, once you get your RKL up and running, you will absolutely love it. I agree, however, that the manual is a disaster. I received my unit on a Friday and spent the entire weekend trying to figure it out with little success, until I could call their customer service. It was furiously frustrating. Instructions should assume zero knowledge on the part of the user and Digital Aquatic's manual is more like a reference tool. It should contain step-by-step details for every single setting. I understand that they are changing the manual, along with a firmware update. Unfortunately, the current manual doesn't explain how to update the firmware. Give them a call; they are very nice and will help you out.
