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
