The HI25 provides wireless convenience with a transmitter powered by a 210mAh CR2032 battery (lasting 6–18 months) and a receiver powered by a standard EU outlet. It operates on a 433.92 MHz frequency, ensuring stable and interference-free performance.
With a wireless range of up to 150m in open areas (20–100m indoors), it covers large homes and offices. Users can choose from 38–60 selectable ringtones and adjust the volume, including a mute mode. Both units feature blue LED indicators, making them suitable for the hearing impaired or noisy environments.
The transmitter is made of durable ABS plastic and rated IP40, meaning it should be placed under cover to avoid direct heavy rain. Compact and lightweight, the HI25 is easy to install and maintain.
