Using / Changing a CTCSS Code
Your radio has 38 CTCSS private codes available. The selected CTCSS code may be different for each channel. To
select a CTCSS code for the used channel, please procede as follows :
1. Enter to Menu mode. Advance through the Menu until the CTCSS Code on the LCD Display blinks.
2. Press the Up or Down key to reach a higher or a lower CTCSS code. Pressing and holding the Up or Down key,
the code selection will move quicker.
3. To exit the Menu, press the PTT or Call key.
Selecting a CTCSS code of “oF” will disable the CTCSS feature. To communicate between two or more radios, both
the channel and CTCSS code selections must be the same. To communicate with other models and brands of radios,
the actual radio frequency and CTCSS frequency must be matched. The frequency chart and CTCSS Code chart are
included to help with this selection.
Notice : there are different systems to generate the CTCSS sub audible tones (tone coding method, time coding
method, etc.) and therefore it might be occasionally possible to have CTCSS compatibility problems among radios
from different manufacturers. In this case, it is suggested to use CTCSS tones with highter tone frequencies (tones #
11 to 38). It is anyway generally reccomendable to use the CTCSS function among radios of the same type. If a
signal with a CTCSS tone different from the programmed tone is received, the communication can not be received
and the BUSY LED Indicator (green color) will be lighted, indicating that the channel is busy.
Voice Operated Transmission (VOX)
Your radio is equipped with a user selectable Voice Operated Transmitter function (VOX), that is used for automatic
voice transmission (handsfree use or baby room monitor use). In this convenient mode, transmission is
automatically initiated by speaking into the microphone and there is no need to push the PTT or Call key.
To set VOX mode :
1. Enter the Menu mode. Advance through the Menu until the VOX icon appears on the display.
2. Press the Up or Down key to select the level of sensitivity (1 or 2) or to disactivate the VOX (oF). When VOX
feature is on, the VOX icon will appear on the LCD display.
3. To exit the Menu, press the PTT or Call key.
