NOTE: The receiver has 51 tone frequencies and conse-
quently their spacing is narrow compared to units having
38 tones. Therefore, some tone frequencies may receive
interference from adjacent tone frequencies.

D Calling a waiting station using pocket beep
A subaudible tone matched with the station's CTCSS tone fre-
quency or 3-digit DTCS code with polarity is necessary. Use
the tone squelch on the next page or a subaudible tone en-
coder (pgs. ??, ??).

I Tone/DTCS squelch operation

241.8
The tone or DTCS squelch opens only when receiving a sig-
250.3
nal with the same pre-programmed subaudible tone or DTCS
254.1
code, respectively. You can silently wait for the specified sig-
nal using the same tone.
q Set the operating frequency in FM mode.
w Program the CTCSS tone frequency or DTCS code in set
mode.
• See steps w to y on p. ?? for programming details.
e Push [MONI•T/T-SCAN] for 1 sec and rotate [DIAL] until
" " or "
r When a signal with the matched tone is received, the
squelch opens and the receiver emits audio.
• When the received signal includes an unmatched tone, the
627 732
squelch does not open. However, the S-meter indicator shows
631 734
632 743
the received signal strength.
