safety issue with the rechargeable batteries sealed into Pure Digital's Oasis weatherproof DAB radio (which by the way is an excellent piece of rugged kit with great sound, other than the safety problem of course).
They offer a freefone number and will arrange free collection and return of your Oasis, and you shouldn't use it in the meantime - "Owners are asked to:
* Immediately switch off the radio
* Remove it from the mains so it does not continue to charge
* Open all four of the rubber stoppers on the right hand side of the radio."
