5.10.3.1 Changing the Priority Channel
If a fixed priority channel is associated with the current scan list, it can be changed if the
Priority option button or menu parameter is programmed. With dual priority, this function
changes only the first priority channel. To change both priority channels, use the Scan List
Edit function described in Section 4.11.5.1, "Group / Priority Scan Lists".
Proceed as follows to change the priority channel using the Priority option button/menu
parameter:
1 Make sure scanning is disabled ( icon not displayed) and the desired scan list is
selected (see Section 4.11.5, "Scan Lists").
2 Select the channel you want to be the priority channel and then press the Priority option
button or select that menu parameter. “Priority” is then flashed to indicate that the
current channel is now the priority channel when scanning that list. Other indications
that may occur are as follows:
- If “No Priority” is displayed, priority sampling may not be enabled on the scan list.
- If “Sel Chan” is displayed, the priority channel is always the selected channel and
cannot be changed.
- If no indication displayed, the scan list may not be user editable or the channel may
not be in the scan list.
5.11 Standard Conventional Calls
Standard conventional calls are placed to other radio units monitoring the selected
channel. The proper coded Call Guard squelch tone or code or P25 NAC may need to be
transmitted by your radio for them to receive a call (see Sections 5.4 and 5.13.3).
5.11.1 Placing a Standard Conventional Call
1 Turn power on and set the volume as described in Section 3.1. Select the channel
programmed for the radio you want to call as described in Section 3.3, "Zone and
Channel Select".
2 Monitor the channel automatically or manually as described in Section 5.1,
"Monitoring Before Transmitting".
3 Press the PTT switch and if the Busy Channel Lockout feature is programmed on the
channel (see Section 5.3, "Busy Channel Lockout"), the transmitter is automatically
disabled if the channel is busy. Otherwise, busy and out-of-range conditions are not
indicated.
