4.1 Display Modes

Upon power-up, the device will display information. Pressing one of the control buttons (typically the top button) will cycle through the display modes:

1. Time Display: Shows the current time in 24-hour format.
2. Temperature Display: Shows the temperature in Celsius (°C) from the connected probes.
3. Voltage Display: Shows the current vehicle voltage (V).
4. Alternating Display: The device can be configured to automatically cycle through time, temperature, and voltage displays at set intervals.

4.2 Setting Time and Other Parameters

To enter the setting mode, typically press and hold one of the control buttons (often the bottom button) for a few seconds until the display changes or flashes. Use the buttons to adjust values and cycle through settings. Due to variations in firmware, specific button functions for setting time, brightness, and display modes may require experimentation. The device primarily supports 24-hour time format and Celsius for temperature readings.

4.3 Brightness Adjustment

The device features three levels of adjustable brightness and an automatic brightness function. This function brightens the display during the day and dims it at night for optimal viewing. Brightness settings are typically adjusted within the device's configuration menu.

5. Maintenance

The MACHSWON 3-in-1 Car Clock Thermometer Voltmeter requires minimal maintenance.

• Cleaning: Wipe the device clean with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
• Probe Care: The temperature probes are waterproof. Ensure their connections remain secure.
• General Care: This device is reusable. Handle with care to prevent physical damage.

6. Troubleshooting

If you encounter issues with your device, refer to the following common problems and solutions:

• Device does not power on:
  • Check all power connections (red wire to +12V, black wire to ground) to ensure they are secure and correctly polarized.
  • Verify that the vehicle's 12V power source is active.
• Incorrect time display or unable to set time:
  • Refer to Section 4.2 for general guidance on setting parameters. Due to the compact design, specific button press sequences for time setting may require trial and error.
  • Note that the device typically uses a 24-hour time format only.
• Temperature reading is inaccurate or not displayed:
  • Ensure both temperature probes are securely connected to the device.
  • Verify that the probes are placed in locations where they can accurately measure the desired temperature.
  • The device displays temperature in Celsius (°C) only.
• Display is too dim or too bright:
  • The device has automatic brightness adjustment. If manual adjustment is desired, access the brightness settings through the device's configuration menu (refer to Section 4.3).
