stand-by mode. This license free radio operates on the 476MHZ
frequency band; the device has 80 available radio channels. If there
are any device users near you, there is a chance that some of the
users are operating on the same radio channel. To prevent you
receiving signals from other users, sub-channels have been
integrated. When using CTCSS, a low frequency tone (between 67-
250Hz) will be transmitted along with the voice signal. There are 38
available tones to choose form. You are free to choose one of the 38
available sub-channels. Due to filtering, these sub-channels will
generally not be audible so they will note disturb the
communication.
