POCKET BEEP AND TONE SQUELCH

■ Tone scan

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.

q  Set the channel to be checked for a tone frequency 

or code.

w  Push [TONE] one or more times to select the tone 

type to be checked.

  • One of the icons “ ,” “ ” or “ ” appear.
e  Hold down [T-SCAN] (TONE) for 1 second to start 

the tone scan.

 • 

Rotate 

[DIAL] to change the scanning direction.

r  When the CTCSS tone frequency or DTCS code is 

detected, the squelch opens and the detected tone 
frequency is temporarily programmed into the mem-
ory or Call channel.

 • 

 

The scan pauses when a CTCSS tone frequency or 
DTCS code is detected.

 • 

 

The detected CTCSS tone frequency or DTCS code 
is used for the tone encoder or decoder, depending 
on the tone condition or type selected in step 

w.

t Push [V/MH  z] to cancel the scan.

z  Set the channel to be checked for a tone frequency.

x  Select the tone type to be checked.
 • 

 

Push [FUNC] 

 then push; [TONE] 

 for repeat-

er tone; [TSQL] 

 for tone squelch; [DTCS] 

 for 

DTCS squelch.

c  Push  [FUNC] 

 then [T-SCAN] 

 to start the 

tone scan.

v  When the tone frequency is matched, the squelch 

opens and the tone frequency is programmed into 
the selected memory or Call channel.

b Push [CLR] 

 to cancel the scan.

 

  NOTE: The detected tone frequency is temporarily 

programmed when a memory or Call channel is se-
lected. However, this will be cleared when the 
memory or Call channel is re-selected.

During CTCSS tone scan

Push [TONE] one or more times to select the tone type.

Hold down [T-SCAN] (TONE) for 1 second.
