Firmware Upgrade
14. Firmware
As with most modern electronics devices, the internal control system of this radio uses a powerful
microcomputer and associated software or firmware. It may be necessary to add new firmware
to the radio to ensure best levels of performance. The new firmware can be uploaded into the
radio using a USB storage device. The upgrading process is simple but some precautions must
be taken to ensure successful results. Please read the following instructions and notes carefully
before attempting a firmware upgrade.
Contact your dealer for details of how to obtain new firmware upgrade files.
Three types of firmware upgrade files are used:
•
System firmware e.g. file name:
CNC_AUTO_Vxxx.rom
•
Bluetooth firmware e.g. file name:
CNC_AUTO_Bxxx.dfu
•
GUI e.g. file name:
CNC_AUTO_Gxxx.img
