TONE SQUELCH AND POCKET BEEP
7-5
By monitoring a signal that is being operated with the 
pocket beep, tone or DTCS Squelch function turned 
ON, you can determine the tone frequency or DTCS 
code necessary to open the squelch.
1.   Set a frequency or select a memory channel to 
check for a tone frequency or DTCS code.
2.   Push [FUNC], and then push [TONE] several 
times, until the icon of desired Tone function is 
displayed.
 •  For a CTCSS tone scan: 
The scan starts without selecting a tone 
function.
3.   Push [FUNC], and then push [T.SCAN] to start the 
tone scan.
 L  To change the scan direction, push [Y] or [Z].
4.   When the CTCSS tone frequency or DTCS code 
is detected, the squelch opens and the detected 
tone frequency is temporarily programmed into 
the selected mode.
 •  The detected CTCSS tone frequency or DTCS 
code is used for the tone encoder or decoder, 
according to the tone condition or type selected 
in step 2.
  - No icon: Cannot be used for the operation.

5.   To cancel the scan, push any key except [ ],  
[Y]/[Z], [MONI] or [FUNC].
Example: A DTCS code scan on 145.20 MHz.
