This compact device integrates multiple functionalities to ensure users have access to information, light, and emergency signaling in various situations.

Function Description:

The primary function of the HRD-900 is to serve as a multi-band radio, capable of receiving FM, AM, SW1, and SW2 frequencies. This allows users to tune into a wide range of broadcasts, including news, weather updates, and entertainment, even in remote areas. Beyond its radio capabilities, the device features an integrated flashlight for illumination, a warning light for signaling, and an SOS alarm for emergencies. Powering these functions is a 2000mAh battery, which can be charged through multiple methods, including a hand crank and a solar panel, making it suitable for off-grid scenarios. The radio also includes an LCD display that shows time, frequency, and battery status, enhancing user convenience.

Important Technical Specifications:
