TONE SQUELCH AND POCKET BEEP

 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 a frequency or select a memory channel to check 

for a tone frequency or DTCS code.

w  Push  [FUNC](M), and then push [TONE](1) several 

times,  until the icon of desired Tone function is dis-

played.

 • 

For the CTCSS tone scan:

  The scan starts without selecting a tone function.

e  Push [FUNC](M), and then push [T.SCAN](3) to start 

the tone scan.

 • 

To change the scan direction, push [

Y] or [Z].

r  When the CTCSS tone frequency or DTCS code is 

detected, the squelch opens and the detected tone 

frequency is temporarily programmed into the select-

ed mode.

 • 

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.

Push       , and then push        several times 

to select the DTCS squelch function.

 [i.e.]: A DTCS code scan on 145.20 MHz.

Shows a term description

When the mouse cursor is moved over a term which 

is highlighted in yellow, the description of term is dis-

played.

Shows the location of keys

When the cursor is moved over a term with a red un-

derline, a red circle appears around the appropriate 

key(s) on the fi gure of transceiver.

Example:  When the cursor is moved over [FUNC](

M) in 

the description, a red circle appears around 

the appropriate key(s).

The screen shots at the right column, correspond to 

the operating instructions and procedures shows both 

setting and operating example.
