Product Description

Note:

1.When the product is outputting high power at H gear, the volume can be properly lowered to reduce the background noise to obtain a better listening effect.

2.The transmitting frequency of TR509 and the antenna must correspond strictly, otherwise it will easily cause damage to the machine.

3. we replaced the power adapter.New power adapter: The adapter head and cable are integrated, and the direct adapter distinguishes the connector shape
Customers please purchase with caution! ! !

4.TR509 has three voltages to choose from: universal American standard or 220V European standard/British standard. When purchasing, please pay attention to whether the voltage you need is the universal American standard or the 220V European standard/British standard. To avoid mistakes, you can note the specifications you need.
