Tecsun Xiegu G90 Instructions

Xiegu G90
Panel Layout and Major Function Controls for the Sight Impaired.
Virtually all the buttons and rotary controls in the G90 are dual function. Hence this is a lengthy
document. These instructions refer to firmware build 1.74 (004)

Front Panel Controls

The G90 has a square LCD display centrally located on the front panel. To the left of the display
there are 2 rotary and one push button control. The push button is the Power On/OFF. Press
this button for 1 second to turn the radio ON. You will hear a beep to confirm this. To turn
the radio OFF, do the same thing-no beep confirmation. When the radio is ON, momentarily
pressing the power button disabled the display, saving power consumption. Pressing any key
turns the display back on.
The two rotary controls to the left of the display are Volume and Multifunction. The uppermost
control is Volume. Depressing the volume control, mutes the speaker and sends the audio to
the headphone socket mounted on the left hand side panel (it is the uppermost 3.5mm socket).
There are many functions that can be controlled through the use of this button. Most are
duplicated by other means described in this guide. As most of the functions require a sighted
person to set the parameters, I have only included those functions that are not duplicated
elsewhere.
SQUELCH. Press the Multifunction control for 1 second. Rotate the Tuning knob until SQL
level is displayed. Press the SAVE button (second from the left of the 5 button group below the
display), the display now returns to normal. Momentarily press the Multifunction button until
the filter bandwidth display is shown without the white end traces, then rotate the Multifunction
control to turn on the squelch function and use the Tuning control to set the level.
TUNING CONTROL. The largest rotary knob on the front panel is used to tuning the frequency
to which the transceiver is to be operated. Repeatedly depressing the tuning knob sequences the
frequency step through the following: 10Hz, 100Hz, 1KHz, 10KHz and 100KHz. Depress
the tuning control for 1 second to enter the RIT adjustment. Rotate the control clockwise for
positive values and anticlockwise for negative values. The total range is 500KHz either side of
the centre frequency.
To access TX POWER adjust function use must be made of a 4 button group located on the
right hand edge of the front panel. The first (top) button is Tune, the second is TX power
(marked POW), the third button is Key and the forth button is Lock.
