The G90 can use a 13.8V external DC power supply. The DC power supply has a current load capacity of at least 10A. The supplied power cord can be used to connect radio and DC power.
When connecting the DC power supply, please carefully connect according to the following figure to avoid reverse polarity of the power supply.
The red wire is connected to the positive pole of the power supply, and the black wire is connected to the negative pole of the power supply .
Note:

Operating
When the G90 uses an external power supply, in order to prevent external interference from entering the radio through the power line or the radio frequency interference in the radio is radiated outside through the power line, we can put the EMC magnetic ring on the power line. Install the magnetic ring as close as possible to the side of the power plug.
The power cord wraps around the magnetic ring 2 turns.
As close as possible to the plug.
When using an external power supply, carefully check the polarity of the power cord and do not reverse the polarity.
The limited warranty of this radio does not include damage caused by an external power connection error or damage caused by improper power supply voltage.
11
External power connection
The G90 uses the Quick Mode button operation to use or turn off various functions. All functions are distributed on each function button (or in the second function). All functions are turned on or off or adjusted and displayed or reminded in the corresponding area on the screen.

Operating frequency band selection
The G90's frequency range covers 0.5 to 30
MHz. Amateur frequencies within this range are divided into multiple bands, and band switching can be performed in a number of
+ - different ways.
Operation method:
Press the BA ND’s < or > button ， Switch to the next or previous operating band separately.
1.8MHz 3.5MHz 5.2MHz 7.1

Insert the data cable into the COMM port, connect the G90 to the computer, and ensure that the computer driver of the data cable is installed correctly. The PC software can control the G90 transceiver;
Adjust the volume of G90 and the input/output volume of ACC port to the appropriate one. Observe the software interface to avoid the Audio frequency amplitude being too large and unable to communicate.
Select the corresponding working mode to perform data communication.
In order to prevent interference, the radio and computer must be well grounded. Please install the EMC magnetic ring for the data cable and audio cable, and install it as close as possible to the radio.
32
Computer control instruction
The G90 uses the standard CIV instruction set. You can use the standard instructions of this instruction set to remotely control the transceiver. It can also be used to configure the control instructions of other software to control the G90.
Band voltage data
The G90's ACC port provides band data for each band. The band data can control the peripheral to automatically switch the band or share the band information with other devices.
