◆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 59} 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.
