To ensure efficient, comfortable and clear communication, the KX-TCA185 DECT handset is equipped with a noise reduction function, which can be enabled at the press of a button. This function reduces surrounding noise and makes the speaker’s voice far easier to hear and understand. Additionally, the KX-TCA185 automatically adjusts the receiver volume to an easy-to-hear level if it detects noise when moving from a quiet place to a noisy place, providing comfortable voice calls without stress.
