Remark ：

1, radio power supply requirements: The maximum output current is not less than 3A, and the linear DC power supply is the best choice. If using switching power supply, the power supply with smaller ripple and better EMC characteristics should be selected.

2, the radio must be connected the antenna before the radio is powered on, a long-time antenna open-circuit working may cause damage to the radio.

3, The radio shell is used for heat dissipation. When working do not touch the radio with hands to avoid the scald.

XZ-DT25-M Software Programming

Default frequency channel is 0,frequency of the 0 channel can be arbitrarily set and saved by the software. Users can input/rewrite any frequency they need in the software. 

Remark: our XZ-DT25-H(25w),XZ-DT25-M(5W),XZ-DT25-L(2W/500mW) and XZ-DT25-U(100mW) can communicate with each other,users can choose suitable radio modems according to actual use.
