I have a three week old NV008S LRF which worked fine until yesterday. The menu button has no effect and therefore it's unusable. Has anybody had that problem? Is there a way to resolve it? Is there a way to reset the scope without using the menu? I've tried taking the battery out putting it back in, turning it on and turning it off. Amazon has offered an immediate replacement but if I can resolve the problem, I'll have the scope back and use faster.
