Privacy Codes

Your microTalk radio incorporates two advanced
coded squelch systems that can help to reduce
interference from other users on any given channel.
CTCSS (Continuous Tone Coded Squelch System)
provides 38 privacy codes and DCS (Digitally Coded
Squelch) provides 83 privacy codes. This provides a
total of 121 Privacy Codes. Either system can be
used on all channels, but both systems cannot be
used on the same channel at the same time.
NOTE: To successfully communicate using a privacy
code, both the sending and receiving radios
must be tuned to the same channel and to
the same privacy code system (CTCSS or DCS)
and privacy code number. Each channel will
remember the last privacy code system and
number you select.
NOTE: The privacy code 00 is not a privacy code,
but allows all signals to be heard on a channel
that is set to 00 both on the CTCSS and
DCS systems.
CTCSS Privacy Codes
CTCSS (Continuous Tone Coded Squelch System)
is an advanced tone coding system allowing you to
select one of 38 privacy codes to reduce incoming
transmissions from other users on the channel.
NOTE: If you are using a CTCSS privacy code, both
radios must be tuned to the same channel and
CTCSS privacy code to communicate. Each
channel will remember the last privacy code
you selected.
To Select a CTCSS Privacy Code:
1. After selecting a channel,
press and release the
MODE button until the
CTCSS icon flashes on the
display. In addition to the
CTCSS icon, either OFF or
the small numbers next to
the channel number will
also flash on the display.
2. If CTCSS and OFF are flashing,
press the CHANNEL UP or
CHANNEL DOWN button to
exit OFF and proceed to select a privacy code.
Or, if CTCSS and the small numbers next to
the channel number are flashing, press the
CHANNEL UP or CHANNEL DOWN button
to select a privacy code.
3. Choose one of the following:
a. Press the MODE button to enter the new
setting and proceed to other functions.
b. Press the LOCK/ENTER button to enter the
new setting and return to LISTENING MODE.
