3.1.26 A/B squelch
This function is used to start squelch by detecting Continuous Carrier Repeater
System (CCRS) carrier signal.
1 Call up the A/B SQ SET screen.
Press the key, and then press
the key while is shown
on the display.
The MEMU will appear. Point the arrow at +SPECIAL
using the dial or UP/DOWN key, and then press the
key.
The SPECIAL menu will appear. Point the arrow at +A/B
SQ SET and then press the key.
The A/B SQ SET screen will appear.
2 Select ON/OFF for A/B squelch.
Point the arrow at ON or OFF using the dial or UP/DOWN key, and then press
the key (the initial setting is OFF).
ON If modulation signals of 2300 Hz used for Continuous Carrier
Repeater System (CCRS) are detected, the squelch is activated
and the sound is muted. If those signals are no longer detected,
the squelch is canceled.
OFF The A/B squelch is disabled.
• Priority order in comparison with the Descrambler and CTCSS decoding
function
The A/B squelch cannot be used with the Descrambler or CTCSS decoding
function.
• If the A/B squelch is turned ON when the Descrambler is active, the A/B
squelch takes priority.
• If the Descrambler or A/B squelch is active, the CTCSS decoding function is
disabled.
• If the A/B squelch is turned ON when the CTCSS decoding function is active,
the CTCSS decoding function is canceled during its use.
Note: • This function may fail if radio or modulation signals are too weak or include
too many noises.
• It is not applicable to Continuous Carrier Repeater System (CCRS) carrier
signal of any frequency other than 2300 Hz.
