In-Call User Alert Enable

(Conventional Personality, Non-ASTRO Call)

Causes the radio to remain muted to normal dispatch calls whenever Voice Mute functionality is activated by the radio-user. Group and individual Call Alerts do unmute the radio for the alert tone to sound. The radio also unmutes to individual radio-to-radio calls such as Selective Calls and Interconnect (Phone Mode) calls. This feature is very useful when a radio-user prefers not to hear normal dispatch traffic, however needs-to remain in radio contact. This feature applies while operating in Non-ASTRO System mode (MDC, DTMF, and QCII) and when on the current Conventional Personality.

When disabled, the radio-user is not able to toggle-on this feature for the current Conventional Personality.

The Voice Mute button-press or the Voice Mute menu-selection allows the radio-user to toggle on and off the Voice Mute functionality for an In-Call User Alert enabled channel.

This Non-ASTRO In-Call User Alert field must be enabled when the Rx Voice / Signal Type field is set to "Mixed Mode" and when the Signaling Type field is set to either " MDC" or " DTMF" or " Quik-Call II".

Also, When Voice Mute is Active:

	Individual or Group Call Alerts decoded by the radio do unmute the radio for the Release Squelch period. The Release Squelch period is defined by this personality’s ASTRO System Select Call / In-Call Reset field selection. Once the Call Alert (sent as an individual call or a group call) unmutes the radio, a voice call that follows can then be a group call that is heard over the radio's speaker, but only until the Release Squelch period has ended.
	If the radio's channel is changed Voice Mute is deactivated by the radio; Voice Mute must be reactivated if desired when returning to the channel.
	If the radio-user presses the PTT button, or launches Emergency Mode, or powers the radio off and back on, Voice Mute is deactivated by the radio.
	MDC Radio Inhibit functionality is possible.
	The Scan mode and Monitor mode features are not possible.
	Other display indications (from group calls) such as receiving LED and PTT-ID (if enabled) function normally.

When the Call Alert Rx / Tx field is set to "Decode" or "Decode & Encode", and

when the Rx Voice / Signal Type field is set to "Non-ASTRO" or "Mixed Mode", and

when the Non-ASTRO Signaling Type field is set to "MDC" or "Quik-Call II" or "DTMF".
