Audio Profiles

Audio profiles provide an easy way to adjust audio settings to match existing working conditions, such as high noise
environments.
The following settings are adjusted by audio profiles:
• Volume Settings for Voice and Tones
• Mic Gain
• Voice Filters such as AGX and noise suppressor
• The type of audio icon to use: yellow [default], red, blue, green or brown; solid or blinking.
One audio profile is enabled by default but up to ten audio profiles can be enabled, the names of which are
configurable by CPS. The audio profiles are based on templates, which are provided by Motorola and are also
managed by the CPS. Several audio profiles can be created, based on the same template.
Audio profiles can be selected by navigating through the radio menu or by selecting a pre-programmed One-Touch
Button.
The name of the active audio profile can optionally be displayed on the idle screen. This is part of the Configurable
Idle Screen feature.

Transmit Automatic Gain Control

The Transmit Automatic Gain Control (TX-AGC) provides flexibility in terms of operating environment. The TX-
AGC allows to transmit from a radio both indoor and outdoor without having to change a profile. The TX-AGC
provides normalized sound levels to the receiving party.

Howling Suppression

The howling suppression is a mode increasing the stability of the acoustic feedback loop. To enable this anti-howling
function use the menu or the corresponding One-Touch Button. The radio eliminates howling caused by the feedback
loop from the receiving radios to the sending radio in simplex calls.
When the howling suppression is enabled, Microphone and Speaker gain reduction values corresponding to the active
audio profile are taken into use.
You can toggle the howling suppression during an active call.
