I take it the 2 belts in you unit are at the dining table. Do you have a sofa or fold out bed, if so they have probably gotten pushed up underneath. I can put mine totally out of site by opening the sofa up a bit and dropping them down the back. Check good down the back of your cushions and open up your sofa or feel down back of coushions. There should be more somewhere.
