ICUA Reset

(Trunking System, Features)

Selects a timed or manual unmute-exception for Trunking call alerts / pages when the channel is Voice Mute In-Call User Alert Enabled. The exception time ( timed or manual) is known as the Release Squelch State. For the two timed selections below, the ICUA Auto Reset Time field (for this Trunking System) partially determines how long the Release Squelch State continues. The Release Squelch State begins when the Voice Mute In-Call User Alert feature is active and the radio has unmuted. This selection applies for the current Trunking System.

When the radio is model / option capable.

SELECTIONS:	DEFINITIONS:
Manual	When the Voice Mute In-Call User Alert Enabled feature is active, pressing the Voice Mute button, or the Voice Mute menu-selection deactivates Voice Mute and ends the Release Squelch State.
Manual	Pressing the PTT button ends the Release Squelch State.
Auto	If the timer expires regardless of whether the radio is muted or unmuted, the Release Squelch State is ended and the Voice Mute In-Call User Alert Enabled rules are again required in order to unmute to any future transmissions.
Auto w/carrier	If the radio is unmuted when the timer expires (due to Carrier Squelch being satisfied) the radio remains unmuted until carrier is dropped. Once carrier is dropped and the radio is muted, the timer is reset and re-started, in effect extending the Release Squelch State again; if the radio then remains muted for an entire timer period (without any carrier override), the Release Squelch State is ended and the Voice Mute In-Call User Alert Enabled rules are again required in order to unmute to any future transmissions.
