I have a portable scale made by the Befour company. I think it is a model# PS-6600. When I turn it on it gives the message "Phd5", flashes, and then gives the message "Lo-b". It is used and did not come with a manual. Any suggestions before I call the company service department?
Just a quick Google search brought this up.

Looks like the rechargable battery needs charged. If it came with an AC adapter, just plug it in. If you bought it used and the previous owner didn't include an adapter, you can find universal ones at Walmart or Radio Shack.
