BOT

LOCK

The “Bottom Lock” Mode shows a “bottom-up” view. The bottom is used as a reference, and all depths are mea- sured from the bottom up.

For more information, see the section on “Performance Modes” on page 50.

Turning the Power On and Off

Press the PWR button once to turn on the power. For a few seconds, the Lamp/Contrast Menu will appear and the panel light will flash on and off. The light will allow you to see in order to set up the display in the dark.

After the screen flashes three times, the unit will go to the display page which was used last (unless this is the first time the unit is powered up). The first time power is supplied to the unit, you will be asked to select the language used by the displays. English is the default language. You may also select any of six other languages. (You can change this setting at any time using the System Setup Menu.)

To turn the power off, press and hold the PWR button for more than 3 seconds.

Setup Memory

When you first turn on the power, the unit will be prepared to operate using a number of preset values. These “default” values are stored in the unit at the factory. (The default values are listed in Section 4.)

This unit has a memory for some of the settings— range, sensitivity, zoom, and frequency. (We will explain these in a moment.) When you turn off the power, any changes you make to these settings will be saved. You can return all of the settings to the factory default values, and reset the trip log to zero. To reset the unit, confirm that the unit is off. Press and hold the

CLEAR button, then press the powers up, release the CLEAR

PWR button for a moment. After the unit button.
