　　KTT9(A)Portable communication phoneIt is the main communication equipment in coal mines. We have Huawei brand mobile phones for easy communication in mines, but there are gas and dust in mines, which makes it difficult to use ordinary phones underground. Therefore, we need to use our mining KTT9 communication phone. Below is a detailed explanation:

　　KTT9(A)Portable communication phoneProduct introduction: KTT9 disaster area telephone is suitable for mining tunnels, disaster areas, underground air defense facilities, underground shopping malls and warehouses, caves, tunnels, border areas, and regional places where electromagnetic waves cannot be transmitted.

　　KTT9(A)Portable communication phoneProduct advantages

　　The KTT9 portable communication phone draws inspiration from today's advanced wired telephone design, using digital integrated circuits for high sensitivity and energy efficiency; Non verbal manual alarm function; The instrument can be used in environments with methane and coal dust (cannot be used in hazardous industrial sites such as petroleum and chemical industries); Multi station relay has continuous communication function (multi station communication distance ≥ 2km); The power communication box is made of silicone and fully sealed; The earphones are sealed with glue for waterproofing. Due to the aforementioned product advantages, this product can be used in conjunction with positive pressure (negative pressure) air oxygen respirators, with clear and reliable communication effects. Continuous and uninterrupted communication, allowing for simultaneous playback and communication.
