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
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.
