XIEGU G1M Operation Manual page 8

When the G1M uses an external power supply, in order to prevent external interference from entering the radio
through the power line, please place a snap-on ferrite choke close to the DC plug. Loop the DC cord through the
choke a few times.
When using an external power supply, carefully check the polarity of the power cord to prevent

the polarity from being reversed.
The limited warranty of this radio does not include damage caused by an external power

connection error, or damage caused by abnormal power supply voltage.

As close as possible to the plug.
