Privacy Codes

Your 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 (Digital ly Coded Squelch)provides 83 privacy codes. 

This provides a total of 121 Privacy Codes. Either system can be used 

on al l 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 0F is not a privacy code, but allows all

signals to be heard on a channel that is set to 0F on both

the CTCSS and DCS systems.

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 Up or 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.

If CTCSS is turned on at the channel selected, 

the display will flash the DCS icon and “OFF”.

To switch from CTCSS to DCS, press the

Channel Up or Channel Down button whi le 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.
