Operation steps:

Find two small holes on the right side of the logic module and mark them as "default" and "reset".

First press the default switch (using a non-conductive needle), then press the reset switch.

The system immediately restarts and enters safe mode. At this moment:

Ignore persistent registry and use default registry.

Do not load any shortcuts in the Windows Startup folder.

The touch screen may be recalibrated.

Custom key mapping is ignored.

In safe mode, problematic applications can be fixed or deleted, and registry settings can be restored. After a normal restart, the system returns to normal.

Maintenance and Cleaning

Screen cleaning: Disconnect the power, use a soft cloth dipped in mild soapy water or 70% isopropanol to gently wipe, and then wipe dry with a cloth moistened with water. Do not use abrasives or solvents.

Anti glare protective film: It is recommended to use the 2711P-RGxx series protective film for easy cleaning and extended screen life.

Battery and backlight disposal: Mercury containing backlights and lithium batteries need to be classified and recycled according to local environmental regulations.
