Harmony 670 universal remote

i have no idea how to operate the features on this remote. this came with no instructions and, when the geek squad installed it, they did not explain it fully. said i needed to go on-line but, cannot get or find out where to get the info.
please help if you can. the races are on and, i really need to record these and be able to retrieve them once they are recorded. it's like trying to find a needle in a haystack at this point.
thank you
