    3.Computer Mode KG-UVD1 handheld transceiver programs by computer, the programming connection and the programming software (KG-UVD1). The programming software can be used in the IBM computer or compatible machine. Duplication Mode 1. “Duplication Mode” can copy the data of a handheld transceiver to another one.
  • Page 4 QUANZHOU WOUXUN ELECTRONICS CO., LTD Model: KG-UVD1 ○ 2 Pressing [MONI] key on duplicated source radio, the duplication starts. When duplicating, the flickering red light means sending data. After duplicating successfully, the red light extinguishes, and the source radio enters the standby mode. If the red light keeps flickering, it means the duplication failed.

The created signal is sent to the changeover on-off on U/V Band.
  • Page 7 QUANZHOU WOUXUN ELECTRONICS CO., LTD Model: KG-UVD1 We can set the bandwidth of all channels by turning on the Wide/Narrow switch. The data from Wide (low level) and Narrow (high level) is outputted by the 14 pin on microprocessors. T528 is connected when receiving the data from WIDE (low level).
  • Page 8 QUANZHOU WOUXUN ELECTRONICS CO., LTD Model: KG-UVD1 8 Receiving Signaling (QT/DQT) The signal from FM IC (U516) enters and is processed by microprocessor (IC811).(See PIC4) Microprocessor IC811 determin whether QT or DQT matches the setting value, and control the output of P-SPK and loudhail by this result.
