HDR 610 Doesn't Power Up
If your HDR 610 doesn't power up, refer to the Installation section, and make sure that:
• the power cable is properly connected to the HDR 610;
• the power cable is wired correctly, with red to positive battery terminal and black
to negative terminal or ground;
• the fuse is operational; a fuse can often appear to be good when in fact it is not;
check the fuse with a tester or replace it with a known good fuse;
• if the unit is wired through a fuse panel, make sure that the panel is powered, as
accessory fuse panels are often controlled by a separate switch, or even the
ignition switch of the boat;
• the battery voltage of the power connector is between 10 and 16 VDC.
Correct any known problems, including removing corrosion from the battery terminals
or wiring, or actually replacing the battery if necessary.
No Bottom Reading on the Display
If there is no bottom reading visible on the display, there are a number of possible
causes for this condition, including:
• if the loss of bottom information occurs only at high boat speeds, then a transducer
adjustment may be needed (refer to the Transducer Installation section);
• check the transducer cable connection on the back of the HDR 610 and make sure
that the cable to the transducer has not been cut or pinched, as even a small
abrasion in the cable can affect performance significantly.
Correct any known problems, including adjusting the transducer, or actually replacing
the transducer cable if necessary.
No Continuous Depth Display in Very Shallow Water
Losing continuous depth when the boat is in very shallow water is normal, because the
automatic range control cannot lock onto the bottom in depths of one foot or less.
Screen Fades, Images Are Not Sharp
If the screen begins to fade, and images are not as sharp as normal, check the input
voltage. The HDR 610 will not operate on input voltages below 10 VDC.
Bottom Reading Disappears During a Hard Turn
Losing the bottom reading temporarily when the boat is executing a hard turn is normal,
as the transducer emerges from the water during such a turn; this condition should
correct itself once the turn is completed.
