The video showcases the channel/function adjustment knob assembly of Hytera PD series walkie-talkies, which is a core operation accessory for professional walkie-talkies:
The first picture shows the internal structural components of the knob. It can be seen that the connection design between the black shell and the white base. The internal metal parts are used to connect with the adjustment modules inside the walkie-talkie (such as channel selection and function switching modules) to achieve precise function adjustment.
The second picture shows the external knob cap of the knob. Its surface is printed with digital scales (such as "3, 5, 7", etc.) and indicator lines, which are used to visually display the channel or functional gear position, facilitating users to quickly identify and switch. The black anti-slip texture design also enhances the convenience of operation.
The third picture shows the entire Hytera PD500 walkie-talkie. The knob assembly on the top (such as the knob on the right) is this type of calibrated adjustment knob, which is used to achieve key operations such as channel selection and function switching. It is the core component for efficient interaction of walkie-talkies in professional scenarios (such as public security and industrial communication).
