Setup Memory and Master Reset

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 Chapter 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, turn it on by pressing the
Power button while holding the Enter button.

Operating Pages

This unit has 3 "pages" or normal displays. These can be used to show
different kinds of information. Here is a list of the three basic pages:
Mode
Downlook page
Window page
Digital page
To select one of the pages, press the Display button, then use one of the
Soft Keys. See Fig. 3-2.
Once you select a page, you can modify the display using one of the
features listed on the Soft Keys at the bottom - Frequency, Zoom,
Bottom Lock and A-Scope. (We will describe these in detail in a
moment.)
On a unit with the optional "Sidelooker" feature, is one more basic page,
for a total of four. For more information, see the section on "Using the
Optional Sidelooker Feature."
