【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ✔【Bicycle Radar for Rear Vehicle Detection】 The Bryton Gardia R300L is equipped with millimeter-wave radar that can detect the distance and speed of vehicles behind you. The detection range is up to 190 meters. Vehicle information is transmitted to your cycle computer or smartphone (using the Gardia app) via ANT+ or Bluetooth. The cycle computer generates voice and graphic alerts to notify you of potential threats. ✔【Bicycle Taillight】 The Brighton Guardia R300L features a bright 73-lumen bike taillight. It is clearly visible even in daylight. This lamp uses a CREE_XPEBRD-L1 LED chip from Cree, ensuring brightness and reliability. It supports five flashing patterns, which can be selected directly or from the cycling computer. Furthermore, the light automatically flashes when a vehicle is detected, warning the driver of the bike's presence. This doubles safety by informing both the rider and the driver. In addition, the Guardia's built-in accelerometer also implements a brake light function. This helps prevent rear-end collisions by signaling slowing down to following vehicles and friends riding with you. ✔【Long Operating Time】The Gardia R300L achieves a long operating time through efficient radar power control. It lasts for 17 hours in daytime flashing mode and 12 hours in constant mode. The remaining battery level is sent to your cycle computer and app for easy checking. It uses a USB Type-C charging port, ensuring convenience for everyday use. ✔【Wireless Connectivity】 The Gardia R300L features ANT+ and Bluetooth connectivity for radar and taillights. Since the ANT+ protocol is standard, it can connect to cycle computers that support ANT+ radar and lights. Even if you don't have a cycle computer, you can use the Bryton Gardia app to view rear-facing vehicle information on your smartphone. ✔【Warranty and Customer Support】 Bryton is a brand originating in Taiwan, specializing in the manufacture of GPS-based fitness devices.
