Installation Instructions

1. Mounting the Gauge:

1. Ensure sufficient space behind the panel for the gauge (55mm / 2 3/16 inches depth).
2. Cut an 85mm (3 3/8 inches) diameter hole in the mounting panel.
3. Insert the gauge into the hole and secure it using the provided screw-down ring.

2. GPS Antenna Installation:

For optimal GPS signal reception, install the GPS antenna in a location with a clear view of the sky.

• The antenna should be installed in front of the vehicle/boat, if possible.
• Avoid placing the antenna under metal surfaces or materials that can shield GPS signals.
• If necessary, reverse the GPS antenna installation to improve signal reception.

2. Parameter Setting Mode:

To enter the parameter setting mode, press and hold the rubber button on the backside of the gauge for 3 seconds.

• RPM Ratio Setting:
  1. While in setting mode, press the button to increase the value. Release the button, then press again to decrease the value.
  2. The adjustable range for the RPM ratio is 1-360, with a minimum step value of 0.1.
  3. Once the desired RPM ratio is set, release the button. The tachometer will automatically save the setup after 3 seconds. If the setting does not meet requirements, re-enter the mode and adjust.
• Fuel Level Sensor & Temperature/Pressure Unit Selection:
  1. Press the button once after entering the parameter selection mode to select the fuel level sensor type (0-190ohm European standard or 240-33ohm American standard).
  2. Press the button twice to select the temperature unit (°F or °C) and pressure unit (psi or bar).
  3. The meter will save automatically after selection.
• Engine Hours Setting:
  1. Quick touch the button 5 times to enter the engine hours setting mode.
  2. Press the button to increase the engine hours value. Release and press again to decrease.
  3. After setting the desired value, release the button. The meter will auto-save after 3 seconds.
• ODO Setting:
  1. Quick touch the button 5 times again (after engine hours setting) to enter the ODO setting mode.
  2. Press the button to increase the ODO value. Release and press again to decrease.
  3. After setting the desired value, release the button. The meter will auto-save after 3 seconds.

Specifications

Maintenance

The MAIMEIMI 6-in-1 GPS Speedometer is designed for durability and minimal maintenance.

• Cleaning: Use a soft, damp cloth to clean the display and housing. Avoid abrasive cleaners or solvents that could damage the screen or finish.
• Waterproof Feature: The device is IP67 waterproof, meaning it is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. This ensures reliable operation in marine and outdoor environments.

Troubleshooting

• Display Visibility in Bright Sunlight: Some users may find the display difficult to read in direct, bright sunlight. This is a characteristic of the TFT screen under certain lighting conditions. Consider installing the gauge in a shaded area or using a sun shield if visibility is consistently an issue.
• Inaccurate RPM Readings: If RPM readings are incorrect, verify the engine cylinder number and ensure the correct speed ratio value is set in the parameter setting mode. Refer to the "Operating Instructions" section for adjusting the RPM ratio. If your specific engine cylinder number is not listed in the manual's recommendations, further adjustment may be required.
• No GPS Signal: Ensure the GPS antenna is installed in a location with an unobstructed view of the sky, away from metal obstructions. Refer to the "GPS Antenna Installation" section for optimal placement.
• Incorrect Sensor Readings (Fuel, Water Temp, Oil Pressure): Check all wiring connections for the respective sensors as per the "Wiring Connections" diagram. Ensure the correct fuel level sensor type (0-190ohm or 240-33ohm) is selected in the parameter setting mode.
• Gauge Not Powering On: Verify the power (Red wire) and ground (Black wire) connections are secure and receiving the correct voltage (9-32V).
