4.2 Securing the HUD

1. Clean the chosen dashboard surface thoroughly to ensure proper adhesion.
2. Peel the protective film from one side of the double-sided adhesive pad.
3. Attach the adhesive pad to the bottom of the HUD unit.
4. Peel the protective film from the other side of the adhesive pad.
5. Carefully place the HUD unit on the dashboard in your desired location and press firmly for a few seconds to secure it.

4.3 Connecting the Power and Data Cable

The A401 supports two connection methods: OBD II for vehicle data and GPS for satellite-based data.

4.3.1 OBD II Connection (Recommended for most vehicles)

1. Locate your vehicle's OBD II port. This is typically found under the dashboard on the driver's side.
2. Connect the provided OBD II cable to the HUD unit's OBD II port.
3. Plug the other end of the OBD II cable into your vehicle's OBD II port.
4. Use the provided crowbar to carefully tuck the cable along the dashboard edges or under trim panels for a neat installation. Secure with the strap if necessary.

4.3.2 USB Connection (For GPS mode only, if OBD II is not available or preferred)

1. Connect the provided USB cable to the HUD unit's USB port.
2. Plug the other end of the USB cable into a car USB charger or a USB port in your vehicle.
3. Note: In USB mode, the HUD will operate in GPS mode only and will not display OBD-specific data such as RPM, water temperature, or fault codes.

5. Operating Instructions

Once installed and powered on, the Acogedor A401 HUD will automatically detect your vehicle's system and begin displaying information.

5.1 Automatic Mode Switching

The HUD automatically switches between OBD and GPS modes based on the connection. If connected via OBD II, it will prioritize OBD data. If only connected via USB, it will operate in GPS mode.

5.2 Display Interfaces

The A401 offers 8 different display interfaces. Refer to the device's physical buttons (if any, not explicitly mentioned but implied for interface switching) or the on-screen menu for navigation.

• Simple Interface: Displays primary data like speed.
• Single Speed Interface: Focuses solely on vehicle speed.
• OBD Basic Interface: Shows fundamental OBD data.
• 6-Grid Interface: Presents multiple data points in a grid layout.
• Turbo Pressure Gauge: Displays turbo pressure (if applicable to vehicle).
• Acceleration Test: For measuring vehicle acceleration performance.
• Brake Test: For measuring vehicle braking performance.
• Full Function Interface: Combines various data points for a comprehensive view.

5.3 Alarm Functions

The A401 is equipped with four alarm types to alert the driver to critical conditions. These alarms can typically be configured through the device's settings menu.

• Speed Alarm: Alerts when a preset speed limit is exceeded.
• Low Voltage Alarm: Warns of low vehicle battery voltage.
• Water Temperature Alarm: Notifies if engine water temperature becomes too high.
• RPM Alarm: Alerts when engine RPM exceeds a set threshold.

6. Maintenance

To ensure the longevity and optimal performance of your Acogedor A401 HUD, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to gently wipe the display screen and the unit's exterior. Avoid abrasive cleaners or solvents, as they may damage the surface.
• Temperature: Do not expose the device to extreme temperatures (very hot or very cold) for extended periods, as this can affect its electronic components.
• Moisture: Keep the device dry. Avoid contact with water or other liquids.
• Cable Management: Ensure cables are not pinched or excessively bent, which could lead to damage.

7. Troubleshooting

If you encounter issues with your Acogedor A401 HUD, refer to the following common problems and solutions:

7.1 No Display / Device Not Powering On

• Check Connection: Ensure the OBD II cable or USB cable is securely connected to both the HUD and the vehicle's port/power source.
• Vehicle Ignition: Confirm that your vehicle's ignition is on. The HUD typically powers on with the vehicle.
• OBD II Port Functionality: If using OBD II, verify that your vehicle's OBD II port is functional (e.g., by testing with another OBD II device).
• Cable Integrity: Inspect the cables for any visible damage.

7.2 Incorrect Speed Reading (GPS Mode)

• GPS Signal: Ensure the device has a clear view of the sky to acquire a strong GPS signal. Obstructions like tunnels or dense urban areas can affect accuracy.
• Calibration: Check the device settings for any speed calibration options.

7.3 No OBD Data (RPM, Water Temp, etc.)

• OBD II Connection: Confirm the OBD II cable is firmly connected.
• Vehicle Compatibility: While designed for all models, some older or non-standard OBD II implementations might have limited data availability.
• Mode Selection: Ensure the device is operating in OBD mode.
• Fault Clearing: The device description mentions "fault clearing" as an OBD function. If a fault code is present, clearing it might resolve some data display issues. Consult your vehicle's manual or a mechanic if persistent fault codes appear.

7.4 Alarms Not Functioning

• Settings: Verify that the alarm thresholds are correctly set in the device's menu.
• Volume: Check if the alarm volume is audible.
