Updating the firmware of your GT Series soldering station helps ensure your system is operating at peak performance.
To update your system’s firmware, follow these 9 simple steps:
STEP 2: Extract the contents of the .zip file. You will find an instruction document and a folder containing the firmware image (.hex).
STEP 3: Transfer the firmware image to the top folder of an external USB drive.
STEP 4: Power down the GT station via the rear panel power switch.
STEP 5: Plug the external drive into the USB port in the back of the GT station (Figure 1).
STEP 6: Press and hold the “Menu” and “⮠ ” buttons simultaneously while switching the power switch ON. Continue to hold the “Menu” and “⮠ ” buttons for 3 seconds, then release. The screen should remain dark for about 10 to 15 seconds. The unit will reset once the software is loaded successfully.
NOTE: The display may show a high contrast. Once the EEPROM is reset and the unit power cycled, the display will be reset properly.
STEP 7: Verify the firmware version by observing the startup page. The model and firmware version will be displayed for a few seconds before transitioning to the home status screen.
STEP 8: Clear the system memory settings (Resetting the EEPROM).
- Press and hold ▼▲ buttons simultaneously while switching the power switch ON.
- When the screen below is displayed (Figure 2), press and release the “Menu” and “⮠ ” buttons simultaneously.
STEP 9: Power cycle the unit as a final step to restore proper default settings.
That’s it. The firmware upgrade is complete! Your GT Series station will now perform with the latest system upgrades.
