TONE SQUELCH AND POCKET BEEP
■
Tone squelch
The transceiver is equipped with 51 CTCSS tone
frequencies, and 104 DTCS codes. CTCSS/DTCS operation
enables you to communicate in the silent standby mode,
since you will only receive calls from group members using
the same CTCSS tone frequency or DTCS code.
NOTE:
Channels 5 and 35 are used for the emergency
channels, and the CTCSS/DTCS function is not
selectable on those channels.

• The selected CTCSS tone frequency or DTCS code is displayed
on the operating screen, when the tone squelch is set to ON or
Pocket Beep is selected.
NOTE:
• The selectable CTCSS tone frequencies and DTCS
codes are listed on the next page.

consequently their spacing is narrow, compared to units
having 38 tones. Therefore, some tone frequencies may
receive interference from adjacent tone frequencies.
