In the boxPedestal, N2QAYB000715 remote/R6 batteries, mains lead, clamp/ferrites and AV terminal adaptors. Optional 3D eyewear and communication camera. Panasonic's 8 March 2012 notice explicitly says US 50/55-inch ST50 models are now available; UK configurations are separate and larger US sizes followed later. Release reflects first confirmed family sale, not the UK review dates.Standard remote, VIERA Touch Pad Controller, pedestal and two pairs of TY-ER3D4MA Bluetooth 3D eyewear. Panasonic's UK manual specifies CR2025-powered glasses; What Hi-Fi? describes them as rechargeable, but AVForums explicitly distinguishes the supplied non-rechargeable 3D4MA from rechargeable 3D4ME. The first on-sale month is unverified, so release uses year precision.
