Select Call / In-Call Reset  (ASTRO)

For the two timed selections, while the Auto Reset Time is running, whenever the radio's PTT button is pressed the timer is stopped and reset; once the PTT button is released the timer is then re-started (from zero) thus extending the Release Squelch State even further.

Manual

For Mobile: Currently this selection does not apply for Selective Calls.

For Portable: A radio-user press of the "Monitor" 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 radio's ASTRO Rx Unmute 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 override) 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 ASTRO Rx Unmute Rules are again required in order to unmute to any future transmissions.

Manual

The following two manual methods of ending the Release Squelch State, also apply to the radio-user when "Auto" or "Auto w/carrier" are selected.

• When the Voice Mute In-Call User Alert Enable feature is active, pressing the Voice Mute button, or the Voice Mute menu-selection deactivates Voice Mute and ends the Release Squelch State.

• Pressing the PTT button ends the Release Squelch State.
