Adjust Screen Contrast

Introduction

It may sometimes be necessary to adjust the screen’s contrast.

Note that this requires access to the ADMIN PIN.

This video will show how to adjust screen contrast on your Fuel Lock device.

Steps

1. From the main lock screen, press * to access the Administration page
2. Enter the ADMIN PIN followed by # to access the Admin Menu
3. Press 3 to access Contrast Settings
4. Press 1 to reduce contrast and 3 to increase

When the desired contrast is reached, press * to return to the main lock screen

Troubleshooting

IMPORTANT: When adjusting the contrast,  first bring it to a very dark level by pressing 3 repeatably then press 1 until the screen is readable.

If issues persist after following these steps, I would advise to re-initialize the screen by power cycling the unit. This is done by removing power from the power source and leaving it for 30 seconds, then powering it back on.
