Firmware Download

Changes from Version 1.13

• - Fixed a bug that caused the transmit output to stop transmitting.

  *If the firmware is updated after the "The RF unit is not detected." dialog is displayed at startup, the firmware of the RF unit is not updated. After restarting, the " RF CPU firmware is wrong version. Retry updating the firmware." dialog will appear.
  In that case, update the firmware from the state that the RF unit is correctly recognized (the state the "The RF unit is not detected." dialog is not displayed).
  If the "The RF unit is not detected" dialog is repeatedly displayed after restarting, disconnect the CX-10G and update the firmware.

The CS-905 programming software used with this firmware can be downloaded here.

• To update the firmware
• 1. Download and unzip the firmware data (for example, 905E114.dat) and copy it into the “IC-905” folder that is on your SD card.
• 2. Insert the SD card with the firmware data into the transceiver. 
• 3. Update the firmware.
• 3-1. Display the SD CARD screen in the Menu. 
• 3-2. Touch “Firmware Update” on the SD CARD screen to open the FIRMWARE UPDATE screen.
• 3-3. Touch [▼] to scroll to the end of the screen to read all the precautions, after you read and agree with all the precautions, touch [YES]. 
• 3-4. The confirmation dialog recommends making a backup of the settings and memories, touch [YES]. 
• We recommend that you make a backup of them in this step, because all the settings and memories may be reset after updating the firmware.
• 3-5. After the backup file is made, and the firmware selection screen is displayed, touch the firmware update data (for example, 905E114). 
• 3-6. Please carefully read all the precautions, and when you want to execute it, touch [Yes] for 1 second to start the firmware update.
• 3-7. When the update is completed, "Firmware updating has completed.” is displayed, and the transceiver will automatically restart.
• If the setting data needs to be converted, it may take some time to restart. 
• 4. If the settings and memories have been reset, load the settings and memories that have been backed up onto the SD card.
• 4-1. Display the SD CARD screen in the Menu.
• 4-2. Touch “Load Setting” on the SD CARD screen to open the LOAD SETTING screen. 
• 4-3. Touch the file name of the saved file. 
• 4-4. Touch “ALL,” and then the dialog “Keep ‘SKIP’ settings in the Repeater List?” is displayed, touch [YES].
• 4-5. The dialog "Load file? The new “REF Adjust” setting will be saved.” is displayed, touch [Yes].
• 4-6. After the loading ends, “COMPLETED! Restart the IC-905.” is displayed, restart the transceiver.
