Good Morning,

I have programed serveral macros and custom codes into my URC-8811. I wanted to know if I remove the batteries completely, will I lose everything I programmed into it?

If I dont lose everything by taking the batteries out, how long can I leave the batteries out of it? Im curious because I might have to send the remote back to the manufacturer for an "upgrade" for a DVD player that I dont have a code for (Apex AD-1225)

Thanks
