    Range will depend on the type of terrain that you are communicating across. The ZA-721 uses the UHF (Ultra High Frequency) band and will be subject to similar obstacle interference as cellular phones. The radio works indoors as well as outdoors.
  • Page 9: Programming (Optional)

    Programming (optional) A programming cable is needed to program different channels or functions on the ZA-721. The programming cable links the radio to USB port on a PC or laptop. USB installation: Plug in the cable to a USB port, the computer should locate the cable and configure it automatically if using window 10.
  • Page 10 Connect the USB cable to the PC and plug-in the twin connector into the speaker/microphone jack on the side of the radio. Ensure that there is a charged battery connected to the radio and switch the radio on. Start the program and a window will appear.
  • Page 11 There are 38 CTCSS standard tones (1-38) plus 12 extra QT tones. The 38 tones are common on other 446 MHz radios such as the Zartek RX8, COM8 or PT8. If the tone is left “OFF”, the frequency is left “open” to receive communication from any tone, but your transmitter will not be decoded by a radio with a tone.
  • Page 12 VOX (Voice-operated Transmission) The ZA-721 has a multi-level sensitivity built-in VOX function. You can enjoy talking and listening without pressing PTT key as transmit is automatically activated by sound. This turns your radio into hands-free “walk & talk” when used with a headset.
  • Page 13: Optional Accessories

    Announce Voice Channel As the channels are changed, a voice announces the specific channel. This is useful when using the radio at night. Power Selection (only in dealer license version) Maximum communication range is achieved when the transceiver is set to high power mode, whilst lower power settings will save battery life.
