Here is something you can try to increase the range of your UHF remotes. This is not mine I just found it while doing some reading. Thanks phantom

How do I increase the UHF remote sensitivity?


--------------------------------------------------------------------------------


Go to SYSTEM INFO screen (one with rcvr and card IDs).
Menu, 6, 1, 3.
Cover the IR emitters on the front of the remote.
Go to the limit of remote control range and press
BROWSE, THEME, then RECORD
Screen flashes

The 4700 will now turn up its gain and the remote is
usable far away and in other rooms.

I've confirmed that this procedure also works on 4000
series receivers. The further away you are when you do
this procedure, the better. You may want to repeat the
procedure from further away, to max out the gain. Of
course, if your receiver has no IR capability, you don't
need to shield the IR emitters on the remote.
