Color Flags, Grid, Text, Waveform, Background
Some color changes are dynamic, meaning you will see the changes as you make
the change; examples include Flag, File, ID. Others, such as waveform and
background, can only be seen once the change is made and you return to the
screen.
Note: the TKG250 will not allow the superimposition of two simultaneous colors.
To change a color, Press Menu/OK, scroll to Display, press Menu/OK, choose the
item to change the color on using the up and down arrows, then use the left or
right arrow to toggle through the color choices of:
Red, green, blue, yellow, white, black, grey, light grey. By varying the colors, you
can optimize ease of visibility and improve contrast. The Wave is readable in
direct sunlight as well as in-doors. It is highly recommended to use the back light
set to on or auto when using the wave indoors. You can not make two colors be
the same and the Wave will prompt you with a message such as wave and
background not allowed and the gauge will move to the next available color.
Using the Clock
The TKG250 has an internal real-time clock that includes the year, month, day and time.
From the Initial Setup screen press menu/OK and scroll to clock and press Menu/OK.
