A branded protective leather case with a flap and a Velcro fastener featuring a transparent window for device control. Specifically tailored for the Radiacode 102/103/103G. The case can be attached to a belt with a width of up to 6 cm. Additionally, there is a metal ring on the back of the case for various carabiners and hooks. Overall case dimensions: 128 x 38 x 26 mm (length x width x height). The case serves multiple purposes: it can be used to carry the device (on a belt/hook), for storage, and protection against physical external factors. The closed design of the case shields its contents from potential splashes, dirt, and dust. However, it does not provide water-tight protection: on one side of the case, there is a regular Velcro flap, and on the opposite side, two small openings are present for technical purposes. The case features three transparent plastic windows: one for the device's display and buttons, another for the external light sensor (which activates the screen backlight in the dark), and the third one for the charging and gamma-ray registration indicator. The largest transparent window (covering the display) also allows for pressing the devices's buttons for adjustment and control.
