Insignia 450TX - Manual (Page 23)

The time, speed and distance
calculations are useful for tracking
your progress on a trip. The input
voltage is useful for determining
the condition of the charging
system of the boat. When used in
a portable application or whenever
the 450TX is operated from a
battery source, the voltage
number can be used to determine
battery life. The 450TX will operate
at voltages from 10 to 20 VDC.
Voltages in excess of 20 or less
than 10 VDC cause the unit to power off. The Triplog resets at power off.
Options. The Options Menu is a series of linked menu
functions used initially to set your preferences. Once
your preferences are selected, it is unlikely these
functions need to be accessed during the normal
operation of the product.
There are thirteen Option menus: Contrast, Display
Speed, Battery Alarm, Bottom Black, Fish ID, Numeral size, Transducer,
Units Speed, Units Depth, Languages, Speed Offset, Depth Offset and
Reset. Press the View button at any time to exit options and return to
normal operation.
Contrast. The Contrast function allows the user to
control the level of contrast of the LCD display. The
450TX will automatically adjust the display contrast to
compensate for changing ambient temperatures;
however, some situations may occur where manual
adjustment will provide a higher level of contrast.
Eleven contrast settings, +5 to -5, are possible. The
display contrast will change as the adjustment is made
so the optimum level of contrast can easily be
adjusted. Use the ARROW buttons to highlight the desired selection.
