Map Page Options

You may also choose to ‘merge’ the four medium, default data ﬁ elds to a single, large ﬁ eld for better

readability, or ‘split’ any or all of the default data ﬁ elds to show 4 small data ﬁ elds. This option is avail-
able from any of the main pages with the exception of the Numbers Page. One the Numbers Page, you
may split each of the 3 large data ﬁ elds into 4 medium ﬁ elds, for a total of 12 data ﬁ elds.

To split or merge the Numbers ﬁ elds:

1. While in ‘Change Numbers’ mode, highlight the data ﬁ eld you want to change and press MENU.

2. Choose ‘Split Number’ or ‘Merge Numbers’, then press ENTER. You will now see four new data

ﬁ elds or one large ﬁ eld. Press QUIT when done.

3. To return to the factory conﬁ guration, repeat the above steps, but instead choose ‘Defaults’, then

press ENTER. Press QUIT when done.

• Measure Distance — allows you to measure the bearing and distance between any two points on

the map display.

To measure the bearing/distance between two points:

1. Highlight the ‘Measure Distance’ option and press ENTER. An on-screen pointer appears on the

map display at your present position with ‘ENT REF’ below it.

2. Move the cursor to the desired reference point (the point that you want to start measuring from)

and press ENTER.

3. Move the cursor to the point that you want to measure to. The bearing and distance from the

reference point, will be displayed in the data window below the data ﬁ elds, along with the cursor’s
coordinates. Press the QUIT key to ﬁ nish.

• Show Sonar/Show Numbers — toggles between a Map Page with Sonar information on the top

portion, or a Map Page with data ﬁ elds on the top of the display.

To show sonar or show data ﬁ elds:

1. Highlight either the ‘Show Sonar’ or ‘Show Numbers’ option and press ENTER. The Map Page will

now be split with sonar and depth information or data ﬁ elds showing on the top.
