SCAN Scan is a useful function for hands-off monitoring of your favorite frequencies. By becoming comfortable with all types of scan, you will increase your operating efficiency. This transceiver provides the following types of scans. Sca Type Purpose Band Scan Scans the entire band of the frequency you selected. Normal Scan Program Scan Scans the specified frequency ranges stored in Memory Channels L0/U0 ~ L2/U2. MHz Scan Scans the frequencies within a 1 MHz range. Memory Scan All-Channel Scans all Memory Channels Scan from 0 to 199 (or from 0 to 99). Scans Memory Channels in Group Scan groups of 20 channels (0 ~ 19, 20 ~ 39, 40 ~ 59, etc.). Call Scan VFO Memory Channel Scans the Call Channel and the current VFO frequency. Scans the Call Channel and the selected Memory Channel. Priority Scan Checks the activities on the Priority Channel (Pr) every 3 seconds. Note: ◆ When the CTCSS or DCS function is activated, the transceiver stops at a busy frequency and decodes the CTCSS tone or DCS code. If the tone or code matches, the transceiver unmutes. Otherwise, it resumes scanning. ◆ Press and hold the Mic PF key programmed as MONI {page 57} to pause scan in order to monitor the scanning frequency. Release the key to resume scanning. ◆ Pressing and holding Mic [PTT] causes scan to stop (excluding Priority Scan). ◆ While scanning, you can change the scan frequency direction by turning the Tuning control or using the Mic [UP]/[DWN] keys. ◆ Starting scan switches OFF the Automatic Simplex Check (ASC) {page 26}. ◆ Adjust the Squelch level before using Scan {page 14}. Selecting a Squelch level too low could cause Scan to stop immediately. 8 37

Purpose
Sca Type
Note:
◆
When the CTCSS or DCS function is activated, the transceiver
stops at a busy frequency and decodes the CTCSS tone or DCS
code.
If the tone or code matches, the transceiver unmutes.
Otherwise, it resumes scanning.
◆
Press and hold the Mic PF key programmed as MONI {page
57} to pause scan in order to monitor the scanning frequency.
Release the key to resume scanning.
◆
Pressing and holding Mic
[PTT]
causes scan to stop (excluding
Priority Scan).
◆
While scanning, you can change the scan frequency direction by
turning the
Tuning
control or using the Mic
[UP]
/
[DWN]
keys.
◆
Starting scan switches OFF the Automatic Simplex Check (ASC)
{page 26}.
◆
Adjust the Squelch level before using Scan {page 14}.
Selecting
a Squelch level too low could cause Scan to stop immediately.
