By scrolling through the

 preferred features of your microTALK

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.

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.

The privacy code 00 is not a privacy code, but allows all signals 

to be heard on a channel that is set to 00 on both  

the CTCSS and DCS systems.

Set CTCSS Privacy Codes 

To select a CTCSS privacy code:
1.

 After selecting a channel, press 

the 

Mode/Power

 button until the 

CTCSS

 icon 

appears and the small numbers next to the 

channel number flash on the display.

If DCS is turned 

on

 at the channel selected, 

the display will flash the  

CTCSS icon and “OFF.” To switch from  

DCS to CTCSS, press the 

Channel Up

  

or 

Channel Down

 button while the display 

is flashing “OFF.” The display  

will then show the small numbers flashing 

and you will then be able  

to proceed to step 2.

2.

  Press using the 

Channel Up

 or 

Channel Down

button to select a privacy code. You can hold the 

Up

 or 

Down

 button for fast advance.

3.

  When your desired CTCSS privacy code is 

displayed, choose one of the following:

a.

  Press the 

Mode/Power

 button to enter the 

new setting and proceed to other functions.

b.

  Press the 

Lock

 button to enter the new setting
