Ideal for simultaneous communication with heavy machinery and various cranes, as well as for base stations for alternating communication!
We propose a solution! It will lead to improved operational efficiency! The DR-PM300SE is a specific low-power transceiver that supports simultaneous calls between 2, 3, or 4 parties, as well as alternating, relay, and linked relay communication. It can also be used in conjunction with the Triplex+ series handheld device (DJ-PM400) that supports simultaneous calls among 4 parties and the helmet type (DJ-PHM20). ■ An all-in-one package including the radio unit with antenna, operation unit, microphone, DC cable, and mobile bracket. ■ The antenna, radio unit, and connection cables are dustproof and resistant to splashes and immersion (IP65/66/67), making them suitable for permanent outdoor installation. ■ The latest noise cancellation feature enables clear communication. ■ The power supply automatically supports DC12V and 24V, allowing for direct installation in large vehicles. ■ The included stand microphone and radio unit with antenna use a magnetic base, making installation easy without special tools. ■ The separately sold wireless microphone, which activates the built-in noise cancellation feature, can be used with both speaker and earphone types. (The speaker microphone EMS-87B is for alternating calls only.) ■ Equipped with features such as VOX, callback (self-monitoring), compander, and dual operation.
