 title: MaixCAM Case
 ---
 
-**The screen protector and lens cover serve as protective measures during shipping. Please remove them before use.**
+## Introduction
 
-MaixCAM comes with a 3D-printed case that protects the hardware of the MaixCAM.
+There are a few accessories to note when you receive your device:
+* **Lens Cap**: Protects the lens during transport. Please remove it before use, otherwise, the image will appear black.
+* **Screen Protector**: To prevent scratches during transport, there is a thin plastic film on the screen. Please remove it upon arrival, as it can severely affect the viewing quality.
+* **Manual Focus Lens**: The lens supports manual focusing. Simply rotate the lens gently to adjust the focus. If the image is blurry, it may be due to incorrect focusing.
+* **Case**: A 3D-printed case that facilitates handling and installation while enhancing aesthetics.
 
 ## Disassembly
 
-It is strongly recommended to choose the package with a TF card. The factory default is already assembled, and you can skip this step and use it directly.
+It is strongly recommended to choose the package that includes a TF card, as it comes pre-assembled from the factory and you can skip this step and use it directly.
 
-The factory default is already assembled. If you need to replace the TF card or solder the pin header, you can try to disassemble it.
+The device is pre-assembled from the factory, but if you need to replace the TF card or solder pin headers, you can attempt to disassemble it.
 
-Here are a few points to note:
-* Make sure to power off before disassembly.
-* There is thermal grease (non-conductive) between the CPU and the case. Please be careful not to get your clothes dirty during disassembly.
-* The heat sink is also in contact with the heat sink plate through thermal grease. Please be careful not to get your clothes dirty during disassembly.
-* Be careful not to damage the camera, touch, and screen cables. Do not break the cables.
-* Pay attention to the direction of the cable, do not plug it in the wrong way.
+Here are some points to note:
+* Ensure the device is powered off before disassembling.
+* There is a thermal pad between the CPU and the case; be careful not to dislodge it during disassembly.
+* Be careful not to damage the camera, touch, and screen ribbon cables (they can easily become loose), and do not break the cables.
+* Pay attention to the orientation of the ribbon cables to avoid inserting them incorrectly.

-## Flash TF Card
+## Flashing the TF Card
 
 There are two ways to flash the TF card:
+* If you bought the official TF card package, it already contains a system, but the version might be outdated. It is recommended to use the USB update method so you don't have to disassemble the casing, which makes it difficult to reassemble.
+* If you are using your own card and have never flashed a system onto it before, you must first flash it using a card reader and then install the TF card by disassembling the device. After that, you can flash the image directly via USB without disassembling.
 
-### Flash TF Card with Card Reader
+### Method One: Flashing the TF Card Using a Card Reader
 
-* Directly remove the TF card, insert it into the card reader, and then insert it into the computer.
-* Open Etcher, select the image file, select the TF card, and click `Flash`.
-* Wait for the flashing to complete, eject the TF card, insert it into MaixCAM, then power on, wait for the system to start, the first boot will be slower, just wait a while.
+* Remove the TF card and insert it into a card reader, then plug it into the computer.
+* Open Etcher, select the image file, choose the TF card, and click `Flash`.
+* Wait for the flashing process to complete, eject the TF card, insert it into the MaixCAM, power it up, and wait for the system to boot. The first boot may be slow, just wait for a while.
 
-### Flash TF Card via USB
+### Method Two: Update the TF Card Image via USB
 
-* Power off MaixCAM, keep the TF card inserted.
-* Hold down the `user` button on the device without releasing it, insert the USB cable connected to the computer, and wait for the USB device to appear on the computer.
-* Open Etcher, select the image file, select the USB device, and click `Flash`.
-* Wait for the flashing to complete, then press the `reset` button or re-power on, wait for the system to start, the first boot will be slower, just wait a while.
+**Note: USB can only be used for updates, not for the first-time flashing.**
+Ensure that the system has already been flashed using a card reader and is **running properly** before using this method.
 
-## System Usage Precautions
+* Power off the MaixCAM, keeping the TF card inserted.
+* Hold down the `user` button, plug in the USB cable to the computer, (or plug in the USB cable first, then hold down the `user` button, press the `reset` button briefly and release it), wait for the disk drive to appear on the computer, and then release the `user` button.
+* Open `Etcher`, select the image file, choose the disk drive, and click `Flash`.
+* Wait for the flashing to complete, then press the `reset` button or power it back on, wait for the system to boot. The first boot might be slow, wait until the screen displays content (to be safe, wait about 1 minute), and do not power off during boot-up to prevent file corruption during system initialization (if this happens, reflash the image).
+
+> If you cannot enter USB upgrade mode, the system files may be corrupted, and you should reflash the TF card using a card reader.
+
+## Points to Note When Using the System
 
 ### Forced Shutdown
 
-It is **not recommended to press the `reset` button** during normal system use, except in the situations mentioned above. This button forces a power cut, and if your system is writing content to the TF card, it could cause system and data damage. Similarly, forcibly unplugging the power while the system is still running poses the same risk as pressing the `reset` button. Always try to **shut down the software before unplugging the power**.
+Other than the above situations where using the `reset` button, it is **not recommended to press the `reset` button** during normal use. This button forcefully cuts off power. If your system is writing content to the TF card, it could cause system and data damage.
+Similarly, forcibly unplugging the power supply while the system is still running poses the same risk. Try to **shut down the software before unplugging the power supply**.
 
-For normal operations, please **shut down or restart using software**. Here are the methods:
+For normal use, please **shut down or reboot via software**. Methods:
+* Method One: From the interface, select `Settings` -> `Power` to perform a software shutdown or reboot.
+* Method Two: In the terminal, use the `poweroff` or `reboot` commands to shut down or restart via software.
+* Method Three: Other software calls, such as using `Python` to invoke `import os;os.system("poweroff")` for shutdown or reboot.
 
-- **Method 1:** Navigate to `Settings` -> `Power` to shut down or restart through the software.
-- **Method 2:** Use the `poweroff` or `reboot` commands in the terminal for software shutdown or restart.
-- **Method 3:** Other software calls, such as using Python `import os; os.system("poweroff")` to shut down or restart.
+### Issues with File Writing and Data Loss
 
+The system uses a caching mechanism. When your code writes a file, it might only write to memory initially, and the system automatically writes to the disk after some time. If the power is cut during this period, the content will not be written to the disk (TF card), and the next time the system boots, the previously written content will be missing.
 
+Solutions:
+* Try not to directly cut off power or press the `reset` button; use the software shutdown methods mentioned above.
+* To save critical content, you can manually call an API to force the content to be written to disk. For example, in `Python`, you can use `os.sync()` to tell the system to immediately write all cached files to the disk. For other methods such as writing to a specific file, and other languages, please search for terms
