A remote control that can operate ON/OFF at a distance of about 50 meters.

The RT-4B is a specific low-power radio device that operates in the 315MHz band and complies with "ARIB STD-T93," featuring a technical compliance mark. Compared to weak radio remote control devices, it allows for longer and more stable communication distances. Additionally, it does not have the directional limitations of infrared remote controls, enabling use without concern for the orientation or location of the transmitter. It can be used in combination with the RR-1A or RRM-1A. 【Features】 ■ One-shot transmission with 4 buttons ■ Communication distance of approximately 50 meters in line of sight ■ Operation confirmation with LED and buzzer ■ Lightweight and slim design
