Connecting to Power Through the Voltage Converter
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or
product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product
specifications. Connecting the power cable without the appropriate fuse in place voids the product warranty.
Do not reuse any voltage converters from previous Garmin radar models, or third party voltage converters. Using
any converter other than one included with the radar, or the correct converter purchased from Garmin or from
your local Garmin dealer may damage the radar or prevent it from turning on.
Some radar models require a voltage converter unit to properly power the device. If your model is packaged with
a voltage converter, it must be installed in order for your radar to function. If your model is not packaged with a
voltage converter, connect the power cable directly to the boat battery
NOTE: Although some radar models do not require and are not packaged with a voltage converter, you can
purchase one from your local Garmin dealer or you can go to buy.garmin.com. Using a voltage converter with
these models allows them to withstand stronger winds. See the specifications section for details.
When installing the voltage converter, observe these considerations.
• The voltage converter requires an input voltage of 10 to 32 Vdc.
• You should install the voltage converter as close as possible to the power source.
• Connecting the power cable for the voltage converter directly to the battery is recommended. If it is
necessary to extend the cable, you must use the appropriate gauge of wire for the length of the extension
