I work for an Audio Visual rental company and this unit has seen occasional use at exhibitions. Very low use.
It has a flip down front.
Fully working.
Region Code B so plays disks from B i.e. Europe, Greenland, French Territories, Middle East, Africa and Australia/New Zealand.
Local collection during office hours from a KT6 postcode. Some weekends from a KT19 postcode but ask in advance.
ftp://ftp.panasonic.com/bluray/om/dmp-bdt310_mul_om.pdf is where you can find the manual. NOTE that the USB function is very limited.
You can collect from a KT19 postcode during office hours if you wish.
Thanks for looking.
