CAUTION: Some boats have 24 or 36-volt electric systems. Be sure your HDR 600 is connected to a 12 VDC power supply.

If you must wire the HDR 600 directly to a battery, be sure to install an in-line fuse holder and one amp fuse (not included), for the protection of the unit. Humminbird is not responsible for over- voltage or over-current failures.

In order to minimize the potential for interference with other marine electronics, particularly VHF radios, it is best to route the transducer cable and the antenna cable as far apart as possible. A separate power source may be necessary to eliminate interference.

USING THE HDR 600

WHAT YOU SEE ON-SCREEN

The HDR 600 uses a backlit 7-segment display in conjunction 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. Figure 1 shows a typical view you might see on-screen at initial power-up.

CONTROL FUNCTIONS

The HDR 600 uses 3 buttons to control the Shallow Alarm, Deep Alarm, Keel Offset, and Units of Measure function. Wile in normal operation, pressing the SET button selects a Function and blinks its corresponding indicator on the display. Once a Function has been selected it may be adjusted by pressing the UP and Down arrow buttons to adjust the setting. Further presses of the SET button will sequentially select the other functions for adjustment. All user settings are remembered by the HDR 600, even when powered off.
