Connect straight key/ morse key according to the diagram shown in the figure above.

Note:

• If the connector of the straight key is a 6.5mm 2-pole plug, please change it to a 3-pole 3.5mm stereo plug according to the wiring method shown in the figure above, and connect the trigger end of the morse key to the “Di” or “Da” terminal.
• Take care that direct use of the 2-pole to 3-pole adapter or incorrect wiring may result the radio in CW transmission status all the time!

Connection of External Power Supply

9-16V external DC power supply can be used for G106. The current load capacity of DC power supply shall be at least 3A. Attached power lines can be used to connect to radio and DC power supply. DC power supply shall be connected in strict accordance with following figure to avoid reverse polarity connection.

The white-core line is connected to the positive pole of the power supply, and the metal-shielded line is connected to the negative pole of the power supply.

Connection of External Power Supply EMC ferrite bead can be applied on power lines to prevent external disturbance from entering radio via power lines and radio-frequency interference in radio from radiating externally via power lines when external power supply is adopted for G106. Ferrite bead shall be installed at the side closing to power plug to greatest extent.

• Polarity of power lines shall be carefully inspected to avoid reverse polarity connection when external power supply is adopted.
• The limited warranty of the radio does not cover damage caused by an error in external power connection or damage caused by an abnormal power voltage.

Operation

G106 calls various functions through the multi-function menu. All functions are allocated to different menu pages and there are 4 function options on each page. The menu items can be switched and called out in the following way:
