About CTCSS

CTCSS helps eliminate interference between different users of

the same frequency, letting you talk and listen to people who are

using other transceivers set to the same frequency and CTCSS

code. This is like having a sub-channel within a channel, giving

you greater communication flexibility. When you set a CTCSS

code — there are 38 to choose from — and turn on your trans-

ceiver’s CTCSS, the transceiver transmits a tone with your trans-

mission, letting you communicate with anyone who has a

transceiver set to the same frequency and code. This tone is too

low for you to hear, but other transceivers can detect it.

If CTCSS is turned on and set to the same tone on the receiving

transceiver, it only receives those transmissions that include the

tone. If two different groups oper-ate transceivers in the same

area on the same frequency, they do not hear each other’s

broadcasts if they both use CTCSS and each select a different

CTCSS tone. Your transceiver’s default CTCSS tone is 100 Hz.

Using a CTCSS Frequency

Follow these steps to set your transceiver to a CTCSS frequency

and then activate or deactivate CTCSS.

1. Turn VOLUME fully counterclockwise to make sure power is

turned off.

2. Set the CTCSS Sliding Switch on the front panel to OFF.

3. Choose a CTCSS code from the table on the next page. Then

use a pointed object such as a straightened paper clip to set

the position of each DIP switch on the bottom of the radio to
