Operating The Hdr 610; What's On The Display; Key Functions - Humminbird HDR 610 Installation And Operation Manual

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.
