1.1 Operating Modes
The rad-ID has only two modes, Detection or Identification. When the rad-ID is first turned on it
will measure the background radiation for 30 seconds, and then start with the Detection Mode
Summary screen. When the Handle Button is pressed, the rad-ID will go into Identification
mode. If the Handle Button is pressed in Identification mode, it will return to Detection Mode.
1.2 Controls
The rad-ID controls consist of:
o
an on/off switch, located on the top panel under the handle
o
three lit buttons under the LCD display, and
o
a button on the tip of the handle.
These three buttons change functions in different menus and are always labeled above the
buttons, at the bottom of the display. The button in the handle is referred to as the Handle
Button. The primary purpose of the Handle Button is to shift the rad-ID between Detection and
Identification modes. A secondary purpose is that the Handle Button will always take the
operator to the top of the menu tree, no matter how deep in submenus the operator is. This
shortcut can be very convenient.
Pressing the Handle Button anywhere in
the Menus will return you to the top-level
Detection or Identification display
1.3 Display
The rad-ID display is a 65,000 color, 320x240 pixel liquid crystal display, backlit for easy
reading in bright sunlight or dark rooms. It is not a touch screen, and is protected from scratches
by a plastic window. The brightness of the display can be adjusted to the preference of the
operator. The display backlight can be set to turn off (by using “Keep Awake Time” in the
menu) after a selected period of time to save power. This can considerably lengthen battery life.
The backlight will only turn off in Detection mode, and only after the rad-ID has not been
touched for the selected go-to-sleep duration. To turn the backlight on again, just press any
button. A button pressed while the backlight is off will not activate any function other than to
turn the backlight back on. The backlight will automatically turn on if an alarm level (operator
selectable) is reached.
