Usage Precautions：

Please note the following during assembly and operation:

1. Static Electricity Protection – Wear an anti-static wristband or gloves during assembly.

2. Avoid Excessive Force – Do not pull wires or connectors forcefully during installation.

3. Verify Input Voltage – Ensure correct voltage before connecting the mainboard to the power supply.

4. Waterproofing & Moisture Protection –

• Keep the mainboard away from water paths.

• Seal all connectors to prevent moisture damage.

5. Cable Management – Separate and secure high-voltage and low-voltage wiring inside the toilet.

6. Power Disconnection – Always unplug the power before reconfiguring or servicing the mainboard to prevent electric shock.

7. Safety Compliance – Use only national-standard leakage protection switches and plugs for reliable connections.
