nal with the same pre-programmed subaudible tone or DTCS
code, respectively.

mode.

e Push [TONE•T-SCAN] several times until “T SQL” or
“DTCS” appears in the function display.
r When a signal with the matched tone is received, the
squelch opens and the signal can be heard.

squelch does not open. However, the S/RF indicator shows the
received signal strength.

transmit; release [PTT] to receive).
y To cancel the tone squelch, push [TONE•T-SCAN] several
