1 Operation Whenever power is applied the depth sounder is active and water depth is displayed. If the sonar signal does not show a bottom the display will indicate “- -”. This can occur if the water is aerated or the maximum depth is exceeded. Shallow Alarm To set the shallow alarm: 1. Press show: for three seconds. The display will OFF for 3 Press Seconds ON Note: The maximum depth decreases as boat speed increases. Alarms Two types of alarms can be set; the Deep Alarm and the Shallow Alarm.
ON 3. Use and to change the value. If either key is held depressed for more than one second the reading will increase or decrease rapidly. OFF ON ON OFF OFF OFF Press simultaneously ON OFF to exit Note: If the reading is increased one step above 600 feet (or equivalent) the display will show OFF and ON the alarm will be disabled. TheOFFalarm can also be disabled by pressing both and for 5 seconds. The word OFF will be displayed but the alarm depth will be retained for future use. 4.
Transducer Setting A Transducer Setting is provided to allow the Explorer D210 to be used with different transducer types. The default setting (= 0.0) is used for most transducers. Some transducers ‘ring’ after the sonar transmit pulse (just like hitting a bell). This ringing can be interpreted as an echo from a shallow bottom. The setting is used to increase the required level that shallow echoes must meet before they will be displayed. 6. To exit this mode, press and hold both ON OFF simultaneously.
Note: The keel offset and units of measure should only be changed on the Master instrument. Master/Slave Selection ON OFF To select the master/slave mode of operation: 1. Apply power while holding down If independent settings are required the link feature can be disabled. . OFF ON To enable or disable the OFF linked mode: 1. Apply power while holding down Hold down during power up ON . OFF OFF 2. When the unit is on.

Appendix B - Troubleshooting No display: Erratic readings while moving: 1. Check DC power connections and DC polarity with voltmeter. 2. Check fuse. No depth reading (--) at all depths: 1. Check transducer for growth or multiple coats of paint. 2. Check the transducer cable for cuts and sharp bends. 3. Check that the transducer connection behind the Explorer D210 is firm and free of corrosion. Erratic readings while moored: 1. Check transducer for growth or multiple coats of paint. 1.
