4. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
4.1 അളവുകൾ
Before installation, ensure adequate space for the speedometer. The required mounting hole diameter is 85mm (3 3/8 inches), and the depth behind the panel should be at least 55mm (2 3/16 inches).

Figure 4: Front and rear dimensions of the speedometer.
4.2 മൗണ്ടിംഗ് നിർദ്ദേശങ്ങൾ
- പാനൽ തയ്യാറാക്കുക: Using an 85mm (3 3/8") hole saw, cut a circular opening in your dashboard or mounting panel. Ensure there is at least 55mm (2 3/16") of clear space behind the panel for the gauge body.
- Insert the Gauge: Carefully insert the speedometer into the prepared hole from the front of the panel.
- ഗേജ് സുരക്ഷിതമാക്കുക: From the rear of the panel, attach and tighten the supplied retaining ring to secure the speedometer in place.

4.3 വയറിംഗ് കണക്ഷൻ
Connect the speedometer to your vehicle's electrical system as follows:
- ബ്ലാക്ക് വയർ: Connect to Ground (-)
- റെഡ് വയർ: Connect to 9-33V DC power supply (+)
Ensure connections are secure and insulated to prevent short circuits.

4.4 GPS Antenna Placement
The GPS antenna is crucial for signal reception. For optimal performance:
- Mount the GPS antenna in a location with a clear, unobstructed view ആകാശത്തിൻ്റെ.
- Avoid placing the antenna directly under metal objects or inside enclosed compartments that could block satellite signals.
- The antenna typically comes with 3M double-sided tape for easy mounting.
Upon initial connection, the speedometer may take approximately 30 seconds to acquire a GPS signal. Subsequent signal acquisition will be faster under clear sky conditions.
5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
5.1 വിവരങ്ങൾ പ്രദർശിപ്പിക്കുക
The TFT screen displays the following information:
- SOG (സ്പീഡ് ഓവർ ഗ്രൗണ്ട്): Current speed, displayed in km/h, mph, or knots.
- ODO (Odometer): Total accumulated distance (0-999999km). This value can be adjusted via the back button.
- TRIP (Trip Meter): Distance traveled for the current trip (0-999.9km). This resets to zero when power is turned off.
- COG (കോഴ്സ് ഓവർ ഗ്രൗണ്ട്): Current direction of travel (Orientation Pointer).
- ബാറ്ററി വോളിയംtage: Real-time vehicle battery voltagഇ (ഉദാ, 13.2V).
5.2 Switching Speed Units
The speedometer supports three units of speed measurement: kilometers per hour (km/h), miles per hour (mph), and knots. To switch between these units:
- Locate the button on the back of the speedometer unit.
- Press this button to cycle through the available units (km/h, mph, knot). The selected unit will be saved automatically.

Figure 7: Illustration of how to switch between speed units using the back button.
5.3 Adjusting Odometer (ODO)
The Odometer (ODO) value can be adjusted using the back button. Refer to the detailed instructions in the included physical manual for specific steps on ODO adjustment, as this typically involves a sequence of button presses.
6. പരിപാലനം
The MAIMEIMI GPS Speedometer is designed for durability and minimal maintenance.
- വാട്ടർപ്രൂഫ് സംരക്ഷണം: The unit is IP67 waterproof, meaning it is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. This ensures normal operation even in wet marine environments.
- വൃത്തിയാക്കൽ: Clean the display and housing with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the screen or finish.
- കണക്ഷനുകൾ: Periodically check all electrical connections to ensure they remain secure and free from corrosion.

7. പ്രശ്നപരിഹാരം
- "No GPS Signal" Display: If the speedometer shows "No GPS signal," ensure the GPS antenna is properly connected and placed in a location with a clear view of the sky. It may take up to 30 seconds for initial signal acquisition.
- Display Readability in Sunlight: In very bright, direct sunlight, the TFT display may be challenging to read for some users. This is a characteristic of some display technologies. Consider adjusting the mounting angle or adding a small shade if persistent issues occur.
- Incorrect Speed Reading: Verify that the GPS antenna is securely connected and receiving a strong signal. Compare the reading with another GPS-enabled device if available.
- വൈദ്യുതി പ്രശ്നങ്ങൾ: Check the wiring connections (red wire to 9-33V DC, black wire to ground) to ensure they are secure and receiving power within the specified voltagഇ ശ്രേണി.
