Under the Menu DISPLAY the following parameters are available:
BACKLIGHT LEVEL [1- 5]
Allows the user to set the level of backlight illumination.
Backlight is always set to off upon startup. The user can turn backlight on by
accessing the menu or by setting the Fn hot key to turn on and off backlight.
Turning the backlight on decreases the operating time. The higher the backlight
level the greater the power consumption. Therefore whenever possible set the
backlight setting to off or as low as possible
BACKLIGHT [Off/On/Auto]
Turns backlight on or off. In the Auto setting the
backlight will turn on if a target is detected or a button is depressed. It will turn off
after a short period of time if no target is detected. This will help save battery life
during use of the backlight.
VISUAL DISCRIMINATION [On/Off]
Turns visual discrimination on/off. This is
conditional on whether discrimination is set to on
D
( not all metal
A
). When
discrimination is set to on(
D)
and visual discrimination is set to on(
D
will now
change to a
V)
any target that has been rejected in the discrimination card will not
generate a tone nor will it display a VDI or hodograph.
With discrimination on and visual discrimination set to off any target rejected by
the discrimination card will not generate a tone however a VDI and Hodograph
display will be seen.
ACCUMULATION [Off/1- 9]
Determines the quantity of signals that will be stored
on the screen before being deleted. The use of accumulation can help in identifying
targets that are spaced close to each other. The given parameter matters only at
included mode
VDI
.
SCREEN SCALE [1... 4]
Allows the user to change the size ratio of the hodographs
displayed on the screen when in mode VDI( not Analog mode). The size of the
hodograph is dependent upon signal strength. Objects that are small and/or deep
will have a very small hodograph and may be difficult to see. Conversely if an
object is large and shallow the hodograph may not fit completely within the screen.
To increase the size of the hodographs from weaker targets use a lower value. To
decrease the sizes of the hodograph then raise the value.
