4. Opsætning og installation
Proper installation is crucial for the accurate performance of your transducer. It is recommended that installation be performed by a qualified marine technician.
4.1 Valg af monteringssted
Select a location on the transom that is:
- Free from turbulence caused by the hull, propeller, or other transducers.
- Accessible for maintenance and adjustment.
- Below the waterline at all speeds.
4.2 Mounting the Transducer
- Position the transducer bracket on the transom, ensuring the transducer face is parallel to the waterline.
- Marker og bor pilothuller til monteringsskruerne.
- Secure the bracket to the transom using appropriate marine-grade fasteners and sealant to prevent water intrusion.
- Attach the transducer to the bracket, allowing for adjustment of the angle.
- Route the transducer cable away from sources of electrical interference and sharp edges, securing it with cable clamps.
4.3 Elektrisk tilslutning
Connect the transducer cable to your compatible Raymarine echo sounder or display unit. If connecting to a, c, e, or eS Series displays, ensure the E66066 adapter cable is used as an intermediary.

5. Betjeningsvejledning
Once installed and connected, the P66 transducer will transmit data to your compatible Raymarine display. Refer to your echo sounder's manual for specific operating procedures.
5.1 Depth Readings
The transducer emits sound waves and measures the time it takes for the echo to return, calculating depth. Ensure your display is set to the correct frequency (50 KHz for deeper water penetration, 200 KHz for higher detail in shallower water).
5.2 Speed Readings
The paddle wheel rotates as water flows past it, generating pulses that are converted into speed data. Ensure the paddle wheel is free from obstructions for accurate readings.
5.3 Temperaturaflæsninger
An integrated sensor provides water temperature data, which is displayed on your connected unit.

6. Vedligeholdelse
Regular maintenance ensures the continued accuracy and performance of your transducer.
- Rensning: Periodically inspect the transducer face and paddle wheel for marine growth, dirt, or debris. Clean gently with a soft cloth and mild soap. Avoid abrasive cleaners or tools that could scratch the surface.
- Paddle Wheel Inspection: Check the paddle wheel for free rotation. If it is stiff or damaged, it can be replaced. Refer to the manufacturer's instructions for paddle wheel replacement.
- Kabelinspektion: Inspect the cable for any signs of wear, cuts, or damage. Ensure all connections are secure and free from corrosion.
7. Fejlfinding
If you experience issues with your transducer, consider the following common troubleshooting steps:
- No Depth/Speed/Temperature Reading:
- Verify all cable connections are secure and free from corrosion.
- Ensure the transducer is properly submerged and free from air bubbles or turbulence.
- Check the settings on your echo sounder to ensure the transducer is recognized and configured correctly.
- Inspect the transducer face for fouling or damage.
- Unøjagtig hastighedsaflæsning:
- Clean the paddle wheel and ensure it rotates freely.
- Check for obstructions around the paddle wheel.
- Verify the paddle wheel is correctly installed and not damaged.
- Intermitterende læsninger:
- Examine the cable for kinks, cuts, or damage.
- Ensure the transducer is not experiencing excessive turbulence from the hull or propeller.
- Check for electrical interference from other onboard electronics.
If problems persist, consult your Raymarine echo sounder's manual or contact Raymarine customer support.
