The CA12CD is a cordless PTT (push-to-talk) headset adapter designed to provide wireless communications and PTT functionality for applications such as Public Safety Dispatch and Air Traffic Control. It works with all H series headsets, and utilizes digital processing (DECT) while operating in the UPCS radio band (1.92-1.93 GHz), adding versatility and convenience to your headset.

Note: The Base Unit and the Remote Unit are paired with each other at the factory in a process called subscription. If you replace your Remote Unit, or if your Remote Unit loses its subscription (shown by a rapidly flashing On-Off Indicator), you can perform the subscription process as follows: Hold both of the Talk (Sending) Fine-Adjust Volume Controls on the top of the Base Unit down. The Base Power Indicator will begin blinking. Hold the Remote Unit’s Listen (Receiving) Fine-Adjust Volume Control in either the up or down position. The Remote Unit’s On-Off Indicator will turn on steadily (no flashing). The Remote Unit will subscribe (or re-subscribe) to the Base Unit, after which the Base Power Indicator will return to the steadily on state and the Remote Unit’s On-Off Indicator will go out. Unplug the AC Adapter from the Base Unit and then plug it back in. Press the Remote Unit’s On-Off Button to enable the RF link and use the CA12CD.Talk (Sending) Fine-Adjust Volume Controls, Listen(Receiving)Fine-Adjust Volume Control.
