Tone alerts
1. Disable All
Allows the user to disable all alert tones (Keypad tones, Call Ringers, Escalert and Talk Permit Tone)
except for the incoming Emergency alert tone.
2. Escalert
The radio gradually increases the volume of a repetitive alert tone (for example, a repetitive tone on
an incoming call). The alert tone volume starts from a predefined minimum volume in the radio and
increases, by a constant step size, until the volume level reaches the maximum volume. This is a
radio-wide feature.
3. Channel Free Indication
This feature sounds an alert tone when a voice call ends. It also sounds when the voice call is
interrupted on the current channel, for example, by interruptions caused by a third radio making an
impolite call or sending an emergency alarm. However, this tone does not sound if the interruption
is caused by a corrupted radio signal. Voice calls include Group Call, Private Call, All Call, and
Emergency Call. A voice call ends when the user of the calling radio releases the Push-To-Talk
(PTT) button, regardless of hang time. This feature alerts the receiving radio that the channel is
available for him/her to respond producing a smoother flow of conversation. This alert tone does
not sound at the end of a Remote Monitor transmission, or during Priority Scan when the voice call
ends while the radio is sampling the priority channel(s). This is a radio-wide feature.
4. Talk Permit
This alert tone sounds after the Push-to-Talk (PTT) button is pressed and the radio is able to
transmit on the channel. This is to prompt the user to begin speaking.
5. Volume Offset (dB)
Sets an offset level for the alert tone volume. Setting this causes the alert tone volume level to be
constantly higher, lower, or equal to the audio volume level controlled by the radio's volume knob.
