Garmin Striker 4 Manuale Proprietario

Measure the water temperature using a different 

thermometer or temperature sensor that is known to be 

accurate.

Subtract the water temperature measured in step 1 from the 

water temperature measured in step 2.
This is the temperature offset. Enter this value in step 5 as a 

positive number if the sensor connected to the device 

measures the water temperature as being colder than it 

actually is. Enter this value in step 5 as a negative number if 

the sensor connected to the device measures the water 

temperature as being warmer than it actually is.

Select Settings > My Vessel > Temp. Offset.

Use the arrow keys to enter water temperature offset 

measured in step 3.

You can enter a keel offset to compensate the surface reading 

for the depth of a keel, making it possible to measure water 

depth or depth below the keel instead of depth below the 

transducer. Enter a positive number to offset for a keel. You can 

enter a negative number to compensate for a large vessel that 

may draw several feet of water.

Complete an action, based on the location of the transducer:
• If the transducer is installed at the water line 

À

, measure 

the distance from the transducer location to the keel of the 

boat. Enter this value in steps 3 and 4 as a positive 

number to display depth below keel.

• If the transducer is installed at the bottom of the keel 

Á

, 

measure the distance from the transducer to the water 

line. Enter this value in steps 3 and 4 as a negative 

number to display water depth. Enter a 0 in this value to 

display depth below keel and depth below transducer.

Select Settings > My Vessel > Keel Offset.

Select   or   based on the location of the transducer.

Enter the distance measured in step 1.

• Push the power cable all the way into the back of the device.

Even if the cable seems to be connected, you should push 

firmly so that it is fully seated.

• Make sure the power source is generating power.

You can check this several ways. For example, you can 

check whether other devices powered by the source are 

functioning.

• Check the fuse in the power cable.

The fuse should be located in a holder that is part of the red 

wire of the power cable. Check that the proper size fuse is 

installed. Refer to the label on the cable or the installation 

instructions for the exact fuse size needed. Check the fuse to 

make sure there is still a connection inside of the fuse. You 

can test the fuse using a multimeter. If the fuse is good, the 

multimeter reads 0 ohm.

• Check to make sure the device is receiving at least 10 Vdc, 

but 12 Vdc is recommended.
