PDATING THE RADIO
’
S FIRMWARE
:
When an update to the software in the radio is needed to either fix a
problem or add a feature a firmware update file will be supplied by
your radio dealer, mostly likely over their website. Unless the file is
marked as essential or contains some features that you wish to use,
you may choose not to update the radio.
Instructions on the step by step process is documented on both
Radioddity and Xiegu’s webpages. The use of the Teraterm program or
similar XModem capable software on a PC connected to the radio via
the USB interface (115200,8,N,1) is required and the process is started
by holding in the volume knob while turning on the radio. In Teraterm
make sure that you enable the 1K block option otherwise the upgrade
can fail, leaving the radio inoperative. If this happens, simply start the
upgrade process again.
This manual is based on a radio with the v 1.3 firmware which was
installed using this process.
