6. Troubleshooting

6.1 Cannot Start the Computer

• Possible Causes:
• Battery depleted.
• Loose or damaged battery connection.
• Solution: Check battery charge and charge if low. If the battery is not charging or the device still does not power on, try reinstalling or replacing the battery.

6.2 Screen Not Displaying

• Possible Causes:
• Screen backlight turned off.
• Display hardware failure.
• System software normality.
• Solution: Check and adjust backlight brightness settings as per the manual. Restart the device to ensure the system returns to normal. If the screen still does not display correctly, the display may need repair or replacement.

6.3 Oscilloscope Cannot Capture Signals

• Possible Causes:
• Oscilloscope input channel is not properly connected.
• Input signal amplitude is too small or too large, exceeding the oscilloscope's range.
• Trigger settings are incorrect.
• Solution: Ensure the probe is correctly connected to the oscilloscope input channel. Adjust vertical sensitivity and timebase settings to capture the signal. Verify trigger mode settings, such as selecting "rising edge" or "falling edge" trigger. Check the connection between the probe and the signal source for stability and ensure the cable is intact.

6.4 Signal Generator Cannot Transmit Signals

• Possible Causes:
• Signal generator is not enabled.
• Signal generator hardware is faulty.
• Output frequency or amplitude settings are incorrect.
• Output interface clip is in the wrong position.
• Solution: Check if the signal generator is turned on and ensure settings (e.g., frequency, amplitude, duty cycle) are correct. If settings are correct and the signal cannot be sent, try restarting the device. If the fault persists, the signal generator may need repair or replacement. Verify the interface port is correctly inserted.

7. Maintenance and Care

Cleaning the Exterior

• Frequency: Clean once a month, depending on the environment of use.
• Method: Gently wipe the device surface with a soft cloth. Do not use chemical cleaning agents, especially those containing alcohol or strong acids/bases, to avoid damaging the casing or screen.

Battery and Power Check

• Battery Maintenance: For devices with built-in batteries, regularly check the battery status. Avoid complete discharge. It is recommended to charge regularly and avoid leaving the device unused for extended periods.
• Charging Specifications: Use the official charger for charging. Avoid overcharging or over-discharging, and ensure the battery operates within its specified voltage range.
• Battery Replacement: If the battery shows excessive attenuation (e.g., does not charge normally or discharges extremely quickly), it needs to be replaced in time.

Storage and Transportation

• Storage Environment: The device should be stored in a dry and ventilated environment, avoiding high temperatures, high humidity, or drastic temperature changes. Do not place it in direct sunlight.
• Transportation: Carry the device by hand. Be careful to avoid drops, especially during transport. It is recommended to use a protective case or special bag for carrying.

Software Update

• Regularly check for new firmware updates. The latest firmware can fix known bugs and improve device performance.
