Hi, I want to change the nickname on my VIP622 receiver. We named it when it was set up, but would like to change it now. I've worked with Dish support to get the the nickname menu- go into Menu - 6 (System Setup) - 1 (Installation) - 9 (Broadband Setup) - 3 (Nickname Setup), and can get to the name. My question is, how do I use the alphanumeric keypad to erase what's in there and enter the new name? Thx.
