Humminbird HDR200 manual Using the Depth Alarm

begin transmitting, and automatically display the digital depth. (If the HDR 200 is wired to a switch other than the ignition switch, turn that switch on.)

Increase your boat speed to ensure that you get a continuous bottom reading as the boat moves. Your HDR 200 and its transducer are designed to operate at up to 75 mph. However, use caution when operating any boat at high speed.

If the HDR 200 performs well at idle or slow speeds, but the display is not continuous at higher speeds, the transducer is not installed properly. Air bubbles or turbulence from the boat hull are passing across the transducer face, blocking the transmitted signal. By following the instruction in “Mounting the Transducer,” you can make simple adjustments that should fix the problem.

NOTE: If the other problems occur, see “Troubleshooting” later in this manual for tips from the Humminbird engineers. If you don’t find the solution there, call our toll-free Customer Service Hotline.

Using the Depth Alarm

The HDR 200 offers a depth alarm that can provide you with an audible alert when the boat is in shallow water. To turn on the depth alarm, press and release the DEPTH ALARM button. (You’ll hear a chirp and see the alarm symbol, which indicates the alarm is enabled). Also the depth for which the alarm is set will be temporarily displayed as a reminder. If you wish to reset the alarm depth, press the button and hold it down. The alarm setting will be displayed and will increase in 1’ increments from 3’ to 20’ and then back to 3’ again. Hold the button down until the depth you desire appears, then release the button. Ensure that the alarm symbol is on and now the alarm will sound whenever the depth of water beneath the boat is sensed to be equal- to or less than the selected alarm depth.

When you want to turn the alarm off, press and release the DEPTH ALARM button a second time.

Section 4: Maintenance

Your Humminbird HDR 200 is designed to give you years of trouble-free operation with virtually no maintenance. Follow the simple procedures below to ensure that your HDR 200 continues to deliver top performance.

If the unit comes in contact with salt spray, simply wipe the affected surfaces with a cloth dampened in fresh water.

When cleaning the LCD screen, use a chamois and non-abrasive cleaner such as windex. Do not wipe while dirt or grit is on the screen. Be careful to avoid scratching the screen.

The transducer face may become dirty from storage or contact with marina environment oil. Oil will cause the face to lose the water contact it needs to maintain efficient operation. Simply clean the face with liquid detergent.

If your boat is out of the water for a long time, it may take a while for the transducer to become thoroughly “wetted” when returned to the water. Also, the turbulence of re-entry may cause air bubbles to form on the transducer face. The bubbles will quickly disappear, or can be removed by rubbing the transducer with the fingers while the transducer is in the water.

Never leave the HDR 200 in closed car or trunk, especially in extreme temperatures.
