To add to the above post.
And the 622 remote shipped for use with TV1 is only IR (5.3 IR); however, and unlike TV2, TV1 can be set up to use both IR & UHF PRO remotes.
To do this, you should get another remote similar to the Blue TV2 remote, such as a 6.3 IR/UHF PRO or 6.2 IR/UHF PRO remote with a Green Key Tab that has a Black 1 on it, and UHF PRO etched into the tab.
Check with the vendors listed at the top of the forum page (The DishStore, Sadoun, etc.) or ebay for the 6.2 IR/UHF PRO with key tabs.
Awhile back, the 6.3 IR/UHF PRO was only available from DISH Network Technical Support for right under $40. They will ship it and charge it to your account. Ask for the
6.3 IR/UHF PRO Remote kit, Part Number 144552.

NOTE: The Blue 2 Tab can be removed once you remove the battery compartment and changed with a Green 1 Tab if you had one.
But on the Green 1 IR remote - the Tab DOES NOT come off.
If you get another remote and the directions are (probably) not clear and you can not find it on the forum, just ask and someone will tell you how to program it.
