Or are rechargeables ones provided.** A: The rechargeable battery is installed in the device. You do not need to buy other battery, you only need to connect it to USB port to charge it. **Q: can the beeper be turned off?** A: Both the clicker for incoming detections and the beeper for threshold/safety exceeded can be turned off. If you do that though, best watch the display closely, as the 3.5 mm socket on the side of it is an analogue data port, not a headphone socket. **Q: How is the time and date set? The 4 front buttons don't appear to access that function??** A: You can set the date and time from Main menu->Init setup->Date Time menu. **Q: How often it has to be calibrated (by third party specialist) to maintain accuracy?** A: Digital meters usually do not require further calibration once they leave the factory. The accuracy remains the same unless you physically change something in the settings. ## Frequently Bought Together - GQ GMC-300E Geiger Counter Nuclear Radiation Detector Data Recorder Beta Gamma X-ray - WERJIA Hard Carrying Case for GQ GMC300 Plus/GMC-320 Plus Radiation Detector - Potassium Iodide Radiation Tablets 130 mg (2 Pack) - (280 Tablets) EXP 10/2032 - Potassium Iodine Pills YODO Naciente, Anti Nuclear Fallout Pills --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/49583813-gmc300eplus-fulfill-digital-geiger-counter-nulcear-radiation-detector-monitor-meter](https://www.desertcart.hr/products/49583813-gmc300eplus-fulfill-digital-geiger-counter-nulcear-radiation-detector-monitor-meter) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-27*
