iPad finds bluetooth Altec speaker but will not pair

I had been using the Altec Lansing in motion Soundblade bluetooth speaker with my iPad with no problem. I brought it on vacation and paired it with another device, and now the iPad will not pair with it. It finds it when it searches, but when it says "not Paired" in the box next to the device number. When I choose it to pair, it thinks for a few seconds and goes back to not paired. Any advice would be appreciated. Thanks!
