6.21.2 Transmitting a Voice Call
Transmit a voice call as follows:
1. Turn the radio on.
2. If required, log-in to the network using a user ID and password. See Section 6.4 beginning on page 16
as necessary.
3. Select the desired talk group for transmitting on.
4. Depress and hold the Push-to-Talk (PTT) button on the hand-held microphone, pause for a moment,
and then speak normally. For maximum clarity, hold the microphone approximately 1 ½ inches from
the mouth and do not shout or whisper into it. If the call is queued by the network, wait for the grant
tone to sound before speaking.
5. Release the PTT button when finished speaking.
Refer to Section 6.30 for detailed information regarding sending and receiving encrypted calls.
6.22 ADJUSTING AUDIO TREBLE LEVEL
The tone of received signals can be adjusted using the radio’s “Treble Menu” as follows:
1. Use to scroll through the menu until “Treble Menu” appears. The radio’s current treble level
setting indicates in the top line of the display. There are four levels available: low, medium, medium-
high and high.
2. Use to increase or decrease.
3. Press the MENU button or wait a few seconds to return to the Dwell Display.
6.23 INTERCOM MODE
The optional intercom mode gives users at multiple control heads connected to the same radio the ability
to communicate with each other without transmitting over-the-air. Turn intercom mode on and off using
the “INTERCOM” menu as follows:
1. Use to cycle through the available menu items until “INTERCOM” appears in the display.
2. Use to toggle between “On” and “Off.”
When intercom mode is turned on:
• Incoming voice calls will override intercom communications for the duration of the voice call. The
radio and associated control heads will remain in intercom mode and intercom communications will
resume when the voice call ends.
• “TG: INTERCOM” appears in the control head’s display when talking on the intercom. This indicates
microphone audio is not sent out on the selected talk group; rather, it remains localized between the
radio control positions (i.e., the control heads connected to the mobile radio).
• If a call exists on the currently selected talk group when a PTT button is pressed at one of the control
heads, “TG: in use” appears in the display to indicate intercom mic audio cannot preempt the call on
the talk group.
