Contrast. The Contrast function allows the user to
control the level of contrast of the LCD display. The
150SX will automatically adjust the display contrast
to compensate for changing ambient temperatures;

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 be achieved. Use the ARROW buttons to highlight the
desired selection. The 150SX will reset to the factory setting when the unit

Use the UP and DOWN ARROWS to select
the desired update rate. The Display Speed
setting is remembered when the unit is powered off.
