Please read this manual carefully for a be�er experience and a full understanding
of the opera�on of the G90/S.
The G90S is the version sold in the People's Republic of China, the G90 is the
version available in other countries. This operation manual is applicable to
both models.
NOTE:
As this is a “So�ware Defined Radio” many things can be changed with a
firmware upgrade. New features can be added and the opera�onal processes
can be changed. Therefore, it is recommended that you ensure your G-90/S is at
the latest firmware level (as of this update of the manual, that was Firmware
v1.78 released on December 31st 2021). If the instruc�ons in this manual don’t
appear to work as expected on your G-90/S it is highly likely that you are at a
different firmware version.
