Constant Able H4 is the Hytera 13-pin PTT for HP600/PD60x class. PD70x 16-pin radios need H3 — not this connector.
Auto-Sensing
The Intelligence Core
Push-to-talks aren’t just an accessory—they’re the core of comms. The Constant Able uses embedded proprietary algorithms to decide, rewire, and adjust gain automatically. Microphone

I had an issue with my original PTTs and DISCO stepped up and made it right. The Constant Able is a great PTT and solves previous connectivity issues I had.

The constant able is far superior to any of the PTTs I've used in the past. Works very well with the Hytera HP782. My only complaint is that they don't have more options for other radios, because I will be buying them for my other radios when they come out.

Works great with my Hytera X1p and Peltor Headset. Would recommend and I will be buying more.
