8. CTCSS OPERATION ON THE FRS BANDS
8.1 CTCSS CODE OPERATION
CTCSS stands for Continuous Tone Coded Squelch System; it is a sub-
audible tone system with 39 selections, labeled CODE01 through CODE39.
CTCSS tones are used on FRS channels where there are several stations
transmitting on the same frequencies within close proximity to one another.
When this occurs, you may hear multiple communications at the same time
to the point where it is impossible to clearly receive and understand the trans-
mission of the person calling you.
The HX471S allows you to program CTCSS codes for each FRS channel. If
multiple signals are transmitted on the channel you selected, you will only
hear the transmission of other stations with the same CTCSS tone that was
programmed in the HX471S. If the radio does not receive the correct tone on
the selected channel, then you will not hear the transmission.
1. Select the FRS channel on which you wish to utilize CTCSS control of
the squelch.
2. Press the [MENU] key to enter the Menu Mode.
3. Press the [] or [] key to select Menu item (CTCSS).
4. Press the [MENU] key to enable adjustment of this Menu item (“CTCSS”
icon will blink).
5. Press the [] or [] key to select the desired CTCSS code number
(CODE01 - CODE39).
6. Press the [MENU] key to save the new setting.
7. Press the PTT key to exit from the Menu mode, and activate the CTCSS
feature.
When CTCSS is programmed the CTCSS code num-
ber will appear to the right of the operating channel
number.
To disable CTCSS operation, select “OFF” in step 5
above.
