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 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.
