3. Setup

3.1. Before Installation

• Inspect the product and connectors for visible damage before use.
• Confirm that the connector type and interface are compatible with the target equipment.
• Confirm that the operating power and electrical conditions are suitable for the selected model.
• Handle electronic modules using appropriate electrostatic-discharge precautions.
• Do not force connectors or apply excessive mechanical stress to the PCB, RF connector, or cable.

3.2. GNSS Antenna Installation

For best GNSS reception, install the antenna with a clear view of the sky whenever practical. Avoid locations close to large metal structures, strong electrical interference sources, transmitting antennas, or other objects that may obstruct or disturb GNSS signals. Antenna orientation and installation environment can affect reception quality and positioning performance.

• Place the antenna on a stable surface and keep its intended receiving side oriented toward the sky.
• Avoid placing the antenna directly underneath large metal surfaces unless the product design specifically supports such installation.
• Keep the antenna and cable away from strong electromagnetic interference sources where practical.
• Avoid sharp bends, crushing, pulling, or repeated movement of the coaxial cable.
• Secure the cable so that the connector is not subjected to continuous mechanical tension.
• For outdoor installations, use suitable mounting methods and environmental protection appropriate to the application.

3.3. GNSS Module Installation

• Install the module on a stable, clean, and suitable mounting surface.
• Provide adequate clearance around connectors and components where required.
• Prevent the PCB from contacting conductive surfaces that could cause an electrical short.
• Use appropriate ESD handling procedures during installation and integration.
• Connect the GNSS antenna to the designated RF input using a compatible connector and cable.
• Do not connect or disconnect RF interfaces in a manner that may damage the connector or circuit.

3.4. Basic Connection Procedure

1. Switch off the host equipment before making connections, where applicable.
2. Connect the GNSS antenna to the appropriate RF interface.
3. Connect the module to the host system according to the applicable interface and wiring requirements.
4. Verify power supply conditions before powering the system.
5. Power on the host equipment and allow sufficient time for GNSS signal acquisition.
6. Check the positioning or status information through the host equipment or compatible software.

4. Operating Notes

• GNSS reception performance depends on antenna placement, sky visibility, surrounding structures, interference, satellite conditions, and system configuration.
• Initial positioning may take longer depending on environmental and receiver conditions.
• Performance specifications are model-dependent and should not be assumed from this general guide.
• If the device does not operate normally, disconnect power and check the antenna, cable, connector, power supply, and host interface.

5. Safety & Handling

• Do not expose the product to conditions outside its specified operating environment.
• Do not drop, crush, disassemble, or modify the product unless the product documentation specifically permits it.
• Keep connectors clean and dry during installation and storage.
• Do not install outdoor antenna equipment during thunderstorms or when lightning risk is present.
• Use suitable mounting hardware and follow applicable local safety requirements for outdoor installations.

6. Maintenance & Storage

• Keep the product dry and free from excessive dust, moisture, and contamination.
• Clean external surfaces gently with a soft, dry or slightly damp cloth when necessary.
• Store the product in suitable packaging when not in use.
• Protect connectors from impact, moisture, and unnecessary repeated mating cycles.
