OPERATING THE HDR 610
Your HDR 610 Digital Depth Gauge sends a sound wave signal and determines distance by
measuring the time between the transmission of the sound wave and when the sound wave is
reflected off of an object. As your HDR 610 transducer receives sonar signals, it converts them to
a digital depth that is shown on the HDR 610 display. The depth reading is continuously updated
as you travel across the water. The liquid crystal display (LCD) offers sharp viewing, even in bright,
direct sunlight, and is continuously lit for nighttime operation.
NOTE: Actual depth capability depends on such factors as bottom hardness, water conditions,
and transducer installation. Units will typically read to deeper depths in fresh water than in salt
water.
WHAT'S ON THE DISPLAY
The HDR 610 uses a backlit 7-segment display, together with a 3-button keypad, to control all user
functions. At initial power-up, the unit will begin normal operation and display the digital depth
and the units of measure. The figure shows a typical view you might see on the display at initial
power-up.
KEY FUNCTIONS
Your HDR 610 uses three bezel keys to control the Shallow Alarm, Deep Alarm, Keel Offset, and
Units of Measure functions. These three keys are the SET, UP Arrow, and DOWN Arrow keys.
While in normal operating mode, pressing the SET key selects a function and causes a
corresponding indicator to blink on the display. Once you have selected a function, you may adjust
its setting by pressing the UP and DOWN Arrow keys. Additional presses of the SET key will
sequentially select the other functions for adjustment. All user settings are remembered by the
HDR 610, even after it has been powered off and back on again.
When in an active function, a single press to an Arrow key will result in a single incremental
adjustment. Pressing and holding an Arrow key will sequence through a range of adjustments. If
no adjustment is made for 5 seconds, the unit will return to normal operation.

SHALLOW ALARM
The Shallow Alarm function can be set for depths ranging from 1 to 20 feet, and sounds an alarm
when the depth measured is less than the setting.
1. While in normal operation mode, press the SET key once to display the Shallow Alarm
setting and to cause the Shallow icon to blink.
2. Use the UP Arrow key to activate the Shallow Alarm and also to increase the selected
value. Use the DOWN Arrow key to reduce the value. Press and hold the UP Arrow key
until you reach the desired depth setting.
NOTE: The maximum Shallow Alarm setting cannot meet or exceed the current Deep Alarm
setting (see Deep Alarm section).
3. After your selection is made, wait 5 seconds for the unit to return to normal operation. The
Shallow icon should now be visible.
4. If the depth of the water is less than the selected value, the alarm will sound and the
Shallow icon will blink to indicate the alarm state. Pressing any key will mute the alarm;
pressing the SET key will mute the alarm and activate the Shallow Alarm function for
additional adjustment. To permanently turn the alarm off, use the DOWN Arrow key to
return the display to Off.
DEEP ALARM
The Deep Alarm function can be set for depths up to 99 feet, and sounds an alarm when the depth
measured is greater than the setting.
