Firmware version 3.35 can be used to fix LCD screen calibration issues on the DL3 and DL3 FE. Contact DataLocker Support to get a download link for the correct version, if you do not already have it.


To calibrate the LCD screen after running the v3.35 updater:

  1. Run the v3.35 updater. The device will restart after the firmware update has completed.
  2. Confirm that the device shows v3.35 in the lower right and corner. Press anywhere on the screen to continue. 
  3. Touch each blinking + on the screen with a stylus pen to calibrate the touch screen. You will be prompted to touch the screen 3 times.
  4. Once the touch screen calibration is finished, the waiting screen will appear.
  5. The numeric password screen will appear and you should be able to enter your password as normal.

To re-calibrate the LCD screen:

  1. Plug your device into a USB port to receive power. The following screen should be shown.

  2. While on the screen above, touch and hold the screen with your finger for 5 seconds. 
  3. The calibration screen will appear and you can re-calibrate your screen by following the steps above, starting at step 3.


If a password screen is shown before the calibration screen repeat the process holding the screen for a longer time.
