Setup and Installation
Proper installation is crucial for optimal performance of your Piranhamax 195c. This section outlines the general steps for mounting and connecting the unit.
Mounting Options
- Tilt and Swivel Mount: The standard mounting option allows for flexible positioning and angle adjustment of the display unit.
- Optional In-Dash Mounting Kit: For a more integrated look, an optional kit is available for flush-mounting the unit into your boat's dashboard. Refer to the kit's specific instructions for detailed installation.
Power Connection
Connect the power cable to a 12V DC power source. Ensure the connection is secure and protected from water ingress. It is recommended to connect the unit directly to the boat's battery or a dedicated fuse panel.
Transducer Installation
The transducer is a critical component for sonar operation. Install the transducer in a location that provides a clear, unobstructed view of the water beneath the boat. Common installation methods include transom mount, in-hull mount, or trolling motor mount. Consult the transducer's specific installation guide for detailed instructions and best practices to avoid cavitation and ensure accurate readings.
