Setting The Water Temperature Offset; Calibrating A Water Speed Device; Alarms Settings - Garmin GPSmap 585 Plus Owner's Manual

Setting the Water Temperature Offset

You can set the temperature offset to compensate for the temperature
reading from a temperature-capable sensor.
1 Measure the water temperature using the temperature-capable transducer
that is connected to the device.
2 Measure the water temperature using a different thermometer or
temperature sensor that is known to be accurate.
3 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.
4 Select Settings > My Vessel > Temp. Offset.
5 Use the arrow keys to enter water temperature offset measured in step 3.

Calibrating a Water Speed Device

If you have a speed-sensing transducer connected to the chartplotter, you can
calibrate that speed-sensing device to improve the accuracy of water-speed
data displayed by the chartplotter.
1 Select Settings > My Vessel > Calibrate Water Speed.
2 Follow the on-screen instructions.
If the boat is not moving fast enough or the speed sensor is not registering
a speed, a message appears.
3 Select OK, and safely increase the boat speed.
4 If the message appears again, stop the boat, and ensure the speed-sensor

wheel is not stuck.
