Hi,
I had exactly the same problem. The battery was placed correctly and the coltmeter measured 2.8V which should be OK. However it did not work. You can try to use a digital video camera to see the infrared light. My Sony camcorder can see infrared light and I use it to test remotes. No light was seen. Since I bought the amp new I did not suspect the remote yet.
Then finally I bought the Duracell DR2025 which has 3.1V output and it worked fine. The Krell remote needs a voltage above 3V and I found that only the Duracell DR2025 worked with this remote.
