Turning On Active Noise Cancellation
Active noise cancellation uses a secondary microphone on the back of the radio to actively filter out noise in loud
environments, making it easier for recipients to discern the speech of the talking party who is in a noisy environment.
Active noise cancellation can be left on regardless of environment. However, when safety features such as Lone-
worker Monitoring or Radio Monitor are activated, the listener may lose awareness of the noisy environment. Tait
recommends users implement supplementary procedures to account for this.
The complementary feature of microphone sensitivity allows the internal and external microphones to be configured to
suit the type of environment the user is in, further improving audio quality. When active noise cancellation is enabled,
sensitivity should be decreased. In a quiet environment, increasing the sensitivity is suggested.
For best results, Tait recommends holding the radio 2.5 - 5 cm (1 - 2 inches) from the mouth and speaking directly into
the radio speaker/mic.
