Earlier this wek I received a new PL-310 from one of the Hong Kong eBay vendors. It worked fine for an afternoon and then started constantly showing the low battery indication. End of functioning PL-310 despite some ideas from the seller and my switching out numerous batteries numerous times. The vendor finally refunded $5 (!) and told me to have it repaired locally. As if. All of my stuff is still packed away, so I can't mess with it. Has anybody run into this problem? If there is no reasonable fix, I'll have a low mileage PL-310 suitable for parts available for the postage. Thanks for any thoughts.
