USING THE 250DX

MENU FUNCTIONS

Numeral Size. Two options are available:

BIG and SMALL. The factory setting is BIG. With this setting, the digital depth and speed and temp numerals are drawn large

enough to be read from across the boat.

The big numerals occupy space on the display that could be used for the graphics

area. Hence, the small numerals option. With small numerals selected, a greater amount of the display area is available for the graphic view. This effectively increases the display resolution of the unit.

Numeral Size settings are remembered when powered off.

Diagnostic. Two options are available: HIDE and SHOW. The factory setting is HIDE. Selecting SHOW

brings up the Diagnostic screen. See the Using Diagnostic section for more information.

Units. The Units function allows the user to select the units of measurement for the depth and speed readout. Metres/KTS, (metres/nautical miles per hour), Metres/KPH (metres/kilometres per hour), FEET/MPH (feet/statute miles per hour)

and FEET/KTS (feet/nautical miles per hour), are available.The 250TX remembers this selection

even when the unit is powered off.

Languages. The language menu displays one of two sets of languages. Language set A includes: English, French, Italian, German,

Norwegian, Swedish, Spanish, and Finnish.

Language Set B provides Hungarian, Danish, Polish, Portuguese, Dutch and English. To select your language, push the UP or Down Arrow Buttons to scroll through the list.
