Boat Battery Connection
The RiverPro/RioPro system uses a 12v Lead Acid battery to provide power. The battery should be re-
placed when the voltage falls below 11 VDC (measure with the cable connected and the power switch on).
Battery replacement can induce both single and double cycle compass errors. The compass
must be recalibrated if the battery is replaced.
The battery is not shipped inside the boat. Connect the battery and close the deck plate
before deployment.
To connect the battery:
1. Turn the power switch off.
2. Open the circular deck plate by turning it counter-clockwise.
3. Place the battery in the compartment. Use the provided foam blocks to secure the battery inside
the compartment.
4. Connect the black flag connector to the battery Negative terminal.
5. Connect the red flag connector to the battery Positive terminal.
6. Check the 4 amp Slo-Blow fuse (size 3AG) is installed in the fuse holder.
7. Close the circular deck plate by turning it clockwise until fully tightened.
