About 5 seconds after unit selection the instrument prompts for the keel depth entry. The display shows , , OFFSET" and, shortly thereafter, the current keel depth setting (0. 0 in the example). os 0. 0 OFFSET = keel depth Push the button until the measured keel depth (1. 2 m in the example) is set. The value increments by 0. 1 m or 1 foot at each press of the button. Incrementing is automatic if you keep the pushbutton pressed. os 1. 2 The setting range is 0. 0 to 3. 0 m or 0 to 9 feet. The set value is stored if the pushbutton is not pressed for 5 seconds. After a double acknowledgement tone the depth is displayed automati33 BASIC CALIBRATION / ALARM cally. The unit now displays the water depth below keel (4. 6 m in the example). --4. 6 Setting and activating the shallow water alarm In unsafe depths and in waters with unknown depths the alarm will warn you in time to avoid shallows and to prevent boat damages. The alarm setting range is 0 m to 120 m (0 to 396 feet). The alarm can be switched off or on by double activation of the pushbutton when the display shows the current depth. The display shows the alarm threshold (0. 0 m in the example) when the alarm is switched on. Set the desired alarm threshold by pressing the pushbutton. Up to 10 m (32 feet) the value increments by 0. 1 m (1 foot), up to 120 m (396 feet) by 1. 0 m (3. . . 4 feet) per button activation. Continuous incrementation is obtained by keeping the pushbutton pressed. After about 5 seconds after setting of the alarm threshold (0. 9 m in the example) the display shows the current depth (2. 7 m in the example) , and the set value is stored. 2. 7 A continuous alarm is sounded if the depth below keel is less than the set alarm threshold (0. 9 m in the example), and the flashing display shows the current depth measurement (0. 7 m in the example). 0. 7 34 ALARM The acoustic alarm can be switched off by pressing the button. It stops automatically when the depth below keel is greater than the set threshold. The alarm function is deactivated if the button is quickly pushed twice when the current depth (2. 7 m in the example) is displayed. 2. 7 Push button Push button off 2. 7 35 TROUBLESHOOTING Troubleshooting Fault: - No depth sounder function Cause and correction: - Check electrical connections per wiring diagram. - No ground echo is received or evaluated correctly. - Check installation instructions for echo sounder.
