HME DX Series beltpacks are the lightest, easiest-to-use and most durable communicators in the industry. Super compact design. Dramatically enhance the life of the beltpack by keeping dirt and moisture out and preventing mechanical failures. Voice prompts inform users of status changes through the headset, such as “change battery” or “out of range.” Electronic mic gain and sidetone adjustments allow for easy, tool-free settings.
