Tone Scan - Icom IC-2820H Instruction Manual

■ Tone scan

By monitoring a signal that is being operated with pocket
beep, tone or DTCS squelch function, you can determine the
tone frequency or DTCS code necessary to open squelch.

w Push [MENU](V/MHz•SCAN)
screen.
e Rotate [DIAL] to select "DUP/TONE..." then push
[MAIN•BAND].
r Rotate [DIAL] to select either "REPEATER TONE,"
"CTCSS TONE" or "DTCS CODE" to be scanned.
tPush [SCAN](TONE•DTMF) to start tone scan.
• To change the scanning direction, rotate [DIAL].

TONE SQUELCH AND POCKET BEEP
yWhen the CTCSS tone frequency or 3-digit DTCS code is
matched, the squelch opens and the tone frequency is
temporarily programmed into the selected feature, such as
memory or call channel.
• The tone scan pauses when a CTCSS tone frequency or 3-digit
DTCS code is detected.
• The decoded CTCSS tone frequency or 3-digit DTCS code is
used for the tone encoder or tone encoder/decoder, depending
on the selected tone condition or type in step r.
- "REPEATER TONE" : Tone encoder for repeater operation
- "CTCSS TONE" : CTCSS tone encoder/decoder
- "DTCS" : DTCS tone encoder/decoder
u Push [V/MHz•SCAN] to stop the scan.
z Set the frequency or memory channel to be
T-SCAN
checked for a tone frequency.
x Selects the tone type to be scanned.
• Push [FUNC] then push; [

c Push [FUNC] then [
the tone scan.
v When the tone frequency is matched, the
squelch opens and the tone frequency is pro-
grammed into the selected mode, such as
memory or call channel.
b Push [
A(MW)] to stop the scan.
CLR
NOTE: The decoded tone frequency is programmed tem-
porarily when a memory or call channel is selected. How-
ever, this will be cleared when the memory/call channel is
re-selected.
