Units of Measure
The X-65 normally shows the depth in feet, speed in statute miles per hour, distance in statute miles, and tem- perature in degrees Fahrenheit. You can change any of these settings us- ing the units of measure menu. To do this, highlight the "Units of Measure" label on the System Setup menu, then press the right arrow key. The screen at right appears. Highlight the item you want to change, then press the right or left arrow key to change it. To erase this screen, press the EXIT key.
Reset Distance Log
If you have a speed sensor attached to the X-65, the unit starts counting the distance you've travelled each time you turn it on. You can reset this distance to zero by turning the unit off and on again, however, it's easier to highlight the "Reset Distance Log" label on the System Setup menu, then press the right arrow key. This resets the log and keeps you in the System Setup menu. To erase this menu, press the EXIT key.
Temperature Graph
Some of the X-65's screens have a temperature graph, as shown at right. Normally, the temperature graph has a 2°
range. On the screen shown at right, the temperature graph has a range from 72° to 74°. You can change this range to 4° or 10° using the "Temp Graph" label on the System Setup menu. Highlight that label, then press the right arrow key until the desired tempera- ture graph range is highlighted. Press the EXIT key to erase the menu.
