6.4.1.6.7 Scan Operation
Scan mode is invoked by pressing the SCAN Transceiver-Menu button. Only the active transceiver is
affected. If the active transceiver is incapable of scan, the Error-Tone should sound. If the active
transceiver is scan capable but there are no scan groups programmed for it, the No-Scan-Groups dialog
shall display. If the active transceiver is scan capable and there are one or more scan groups
programmed for it, the Select-Scan-Group dialog shall display.
The No-Scan-Groups dialog is displayed when an attempt is made to start scan mode on a transceiver
that has no scan groups associated with it. The page is depicted in Figure 26. The OK soft button or
the HOME button shall be used to dismiss the dialog. All other buttons and knobs are ignored.
The Select-Scan-Group dialog is displayed when scan mode is started on a transceiver that has one or
more associated scan groups. This page, depicted in Figure 27, shall allow the operator to select one of
the transceiver’s scan groups for scanning.
The first time the Select-Scan-Group dialog is displayed after a power cycle, the first (lowest numbered)
scan group assigned to the active transceiver shall be focused. For subsequent invocations of the page,
the most recently selected scan group for the active transceiver shall be focused. The last selected scan
group need not be retained when power is lost.
All available scan groups for the transceiver shall be displayed, both by number and alphanumeric
identifier. The operator shall be able to select a group by touching it directly on the screen, or by using
the cursor/value knobs. When the value knob is turned, the focus rectangle shall traverse the list,
scrolling as necessary. When the cursor knob is turned, the focus rectangle shall move between the list
and the Edit, Scan, and Cancel buttons.
