Main advanced functions
SQL (squelch)
Squelch mutes the device's speaker when there is no reception. With the squelch level set correctly,
the sound will only be heard when a signal is being received and will significantly reduce battery con-
sumption. It is recommended to set the level to 5.
VOX (voice activation of transmission)
Using the Vox function, you can activate transmission with your voice. When the device stops detecting
sound, then it will automatically stop transmitting. It is recommended to adjust the sensitivity of the
VOX function so that transmitting is smooth and is not triggered by the quietest sounds (the higher
the VOX value, the higher the volume level needed to start transmitting).
W/N
The W/N function gives you the option to switch between the frequency ranges of the transmission
channel: narrow and wide. In areas where radio wave interference may occur, it is recommended to use
the narrow transmission band.
TDR (dual watch / dual reception)
When TDR mode is activated, the device receives simultaneously on frequencies (channels) A and B.
Shortwave radio uses a specific frequency until the signal fades.
TOT
The TOT function allows you to set the transmission time limit in the range of 15-600 seconds.
The function starts automatically when the PTT button is pressed.
CTCSS/DCS
CTCSS/DCS are a kind of "access codes" that allow a device to communicate with a closed group
of users transmitting/receiving on the same frequency or channel. You only need to enter the correct
CTCSS/DCS code to initiate communication. The use of CTCSS/DCS codes does not guarantee com-
plete confidentiality of communication.
