Icom IC-208H instruction manual Tone scan, Push TONET-SCAN for 1 sec. to start the tone scan

10 POCKET BEEP AND TONE SQUELCH

■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 a squelch.

qSet the desired operating frequency or memory channel to be checked for a tone frequency or code.

wPush [TONE•T-SCAN] several times to select the tone type, tone squelch or DTCS, to be scanned.

•Either “T SQL” or “DTCS” appears

ePush [TONE•T-SCAN] for 1 sec. to start the tone scan.

•To change the scanning direction, rotate [DIAL].

Push [TONE•T-SCAN] for 1 sec. to start tone scan.

During CTCSS frequency scan During DTCS code scan

55

rWhen the CTCSS tone frequency or 3-digit DTCS code is matched, the squelch opens and the tone frequency is temporarily programmed into the selected condition 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 w.

- “T SQL”	: CTCSS tone encoder/decoder
- “DTCS”	: DTCS tone encoder/decoder

tPush [TONE•T-SCAN] to stop the scan.

zSet the frequency or memory channel to be

T-SCAN checked for a tone frequency.

xSelects the tone type to be scanned.

•Push [FUNC] then push; [SIMP 9(TSQL)] for tone squelch; [HIGH 4(DTCS)] for DTCS squelch.

cPush [FUNC] then [SCAN 2(T-SCAN)] to start the tone scan.

vWhen 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.

bPush [CLR A(MW)] to stop the scan.

☞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.
