Installing the Fishfinder 400C

Step 1: Select a Location for the Fishfinder

Consider the following when you select an installation location:

•Provides optimal viewing as you operate your vessel.

•Allows easy access to the unit’s keypad.

•Is strong enough to support the weight of the fishfinder and protect it from excessive vibration or shock.

•Allows room for the routing and connection of the power/data and transducer cables. There should be at least a 3-inch (8 cm) clearance behind the case.

DO NOT mount the unit in an area that is exposed to extreme temperature conditions.

NOTE: The temperature range for the Fishfinder 400C is 5°F to 131°F (-15°C to 55°C). Extended exposure to temperatures exceeding this range (in storage or operating conditions) may cause failure of the LCD screen. This type of failure and related consequences are NOT covered by the manufacturer’s limited
