Question about Motorola TLKR T92 H2O Duopack

No, this is a PMR446 device, does not need a licence in Switzerland and the EU (there may still be a few exceptions, don't know, look it up if in doubt). I don't know the models well, but the T92 certainly has IP67 (dustproof + waterproof up to 1 m 30 minutes), an emergency button and a whistle. I can't say much about the rest.
