OPERATION The FI-503 Digital instrument provide depth, wind, boat speed and envi- ronmental information, on three separate displays. Various navigation alarms and distance counters are also provided. Operating Controls, Display Layout UPPER display (Depth and wind angle information and associated alarms)
1. OPERATION Turning the Power On/Off To power the instrument, press the UPPER key. All LCD segments go on and off and then the last-used display appears. To power off the instrument, press the UPPER and MIDDLE keys to- gether. The timer appears and counts down from three seconds to one second, and then the power goes off.

1. OPERATION Selecting Apparent or True Wind Angle, Wind Speed You can show wind angle and wind speed in apparent or true wind. The apparent wind is the actual flow of air acting upon a sail, or the wind as it appears to the sailor.
1. OPERATION Alarms There are eight conditions which trigger audio and visual alarms: Shallow alarm, Deep alarm, Shallow anchor alarm, Deep anchor alarm, High ap- parent wind angle, Low apparent wind angle, Maximum true wind speed alarm, and Low true wind speed alarm. 1.

1. OPERATION 2. If the selected alarm page shows “Off,” press and hold down the SELECT/CLEAR key until an alarm setting appears. 3. Press the LOWER and SELECT/CLEAR keys together to enable adjustment. The alarm setting starts flashing. 4. Press the LOWER key to lower the setting; the SELECT/CLEAR key to raise it.
1. OPERATION Timers Three timers are provided on the lower display: • Count-up timer (stopwatch) • Count-down timer (two provided) Time is displayed in seconds or minutes, depending on counter values. Once you have set a timer, you can leave that page and select any other display.
1. OPERATION To stop or restart the timer, press the SELECT/CLEAR key momen- tarily. A short beep sounds when the timer is stopped or restarted. To stop and reset the timer to start value, press the SELECT/CLEAR key until you hear a long beep. The timer is stopped and reset to start value.
MAINTENANCE, TROUBLESHOOTING This chapter provides the information necessary for keeping your equip- ment in good working order. WARNING Do not open the equipment. Only qualified personnel should work inside the equipment. Preventive Maintenance Following the recommended procedures below will help maintain perfor- mance.
2. MAINTENANCE, TROUBLESHOOTING Troubleshooting If you feel the equipment is not functioning properly, follow the proce- dures in the table below to try to restore normal operation.
