 Scan operationD Full/programmed scanFULL SCAN: Repeatedly scans all frequencies over anentire band (the 144 MHz band or the 430(440) MHz band).PROGRAMMED SCAN: Repeatedly scans between twouser-programmed frequencies. Used for checking for fre-quencies within a specified range such as repeater outputfrequencies, etc. Four pairs of scan edges are available.4 ADVANCED FUNCTIONS18➀ Push [VFO] to select VFO mode.➁ Push [(BAND)SCAN] for 1 sec.; then, while continuing topush [(BAND)SCAN], rotate the tuning dial to select thedesired scan range.➥ The following scan ranges are selectable:• “ALL 144” for full scan on the 144 MHz band.• “ALL 430” or “ALL 440” for full scan on the 430(440) MHzband.• “PROG 1” to “PROG 4” for one of the programmed scans.➥ After releasing [(BAND)SCAN] the selected scan starts.➥ To activate the previously selected scan, dial rotation isnot necessary—just push [ (BAND)SCAN] for 1 sec.➥ During scan, the following can be changed:• Scan range using [(BAND)SCAN], with/without [DIAL].• Scan direction using [DIAL].➂ To stop the scan, push [(VFO) CLR].NOTE: For programmed scan, scan edges must be pro-grammed in advance (1A/1B are programmed by default).Program scan edges in the same manner as regularmemory channels (p. 15)If the same frequencies are programmed into a pair ofscan edges, programmed scan edge flashes, such as“P1,” but programmed scan does not proceed.FULL SCANPROGRAMMED SCANBandedge (e.g. 144.00) Band(e.g. 148.00) edgeScanJumpBandedge BandedgeScanJumpScan edges
