Activating Dehumidification function
1. Turn off the LED display and power off the LED display controller.
2. When using the LED display, turn on the LED display controller and the LED display.
* You can notice that, according to the dehumidification time you set, the brightness of your LED display changes from dark
to bright gradually. When the highest brightness level is reached, the brightness returns to the default value defined by user
automatically.
3. Whenever you turn on the LED display, the dehumidification function starts working automatically after the LED display
controller is activated.

Cancelling Dehumidification function
1. In the brightness adjustment screen, deselect the Enable Dry mode checkbox.
2. Click Send and Save to HW.
3. After setting is complete, the dehumidification function must be disabled. Whether the LED display is under normal operation
or during execution of dehumidification, the dehumidification function can always be cancelled with immediate effect
regardless of its current status.

Notes
1. Dehumidification function has to be used with specific LED display controller program. If your LED display shows that the LED
display controller you are using has not been upgraded with corresponding program, please contact us for support.
2. The maximum value you can set for dehumidification duration is 240 minutes, while the minimum value allowed is 5 minutes.
3. The principles of duration and brightness enhancement:
4. Based on the duration set by user, it will be divided into 15 proportional levels automatically. The display brightness will also
be divided into 15 levels ranging from level 0 for a black screen to level 255 for a brighter screen. As duration level increases,
brightness level will be adjusted to fit the duration level.
5. For example, when Duration is set to 150 min, then brightness changes every 10 minutes, brightness level changes 256/15
every time, meaning that brightness level increases by 17% every 10 minutes.
6. Referring to the dehumidification principle, it is suggested to set the dehumidification time based on the data listed below.
You can also adjust the dehumidification time in accordance with your actual situation.
7. Dehumidification is not a must function of the LED display, but it is indeed a desirable option as it can reduce problems
associated with the presence of humidity such as low performance and shortened lifespan. In most cases, dehumidification can
be cancelled and only be used when necessary.
