About this item
Push-to-talk intercom allows you to use this as a multiple handset walkie talkie system to instantly communicate with any or all of the handsets within the system. No need to shout throughout the house anymore. The frequency band has been extended allowing the signal to be reproduced and tuned for a fuller and cleaner sound, and with the touch of a button, the handset speakerphone makes hands-free conversation easy.
