2. SYSTEM OVERVIEW
5
!
Color Touchscreen — A high-resolution color touchscreen which provides the soft S
and N buttons, and (where appropriate) soft keyboards for entering data such as passwords,
filenames, and alarm limits.
!
Help Messages — Messages at the bottom of the screen both (1) display radiation and
system error alarms, as shown in Fig. 1; and (2) tell you what the next press or tap of the S
and N buttons will do, as shown in Fig. 2.
NOTE
Be sure to watch this message area carefully. If at any time you press or tap a
button and don’t get the result you expected, check the message area to see if an
alarm notification is displayed. The HX forces you to acknowledge each alarm by
pressing or tapping S before you can continue.
!
Alarm LEDs — A panel of four alarm LEDs at the top of the computer’s bezel, as shown in
Fig. 14 on page 18. From left to right, as you hold the HX, they are: red (threat), yellow
(suspect), green (innocent), and amber (error). For more information on alarms and alarm
indicators, see Section 2.5.
!
Status Readouts — Indicators at the top of the screen (Fig. 3) that show the current
dose rate in user-selected units (see Section 3.3.5.2), the current gamma and neutron count
rate, the number of spectra that can be stored on the memory card, the power source (external
power or battery), battery time remaining, the on/off state of the audio and vibration alerts,
and an on-state indicator for the LCX identification mode (for experienced spectroscopists;
Section A.5).
!
Real-Time Identification Area — Located in the center section of all monitoring screens
(as distinguished from the End Survey Report screen). This area lists the names of any
radioisotopes currently being detected, and their classification as a threat or innocent
material. Each ID is color-coded according to its alarm type. See Fig. 4. The alarm displays
are described in Section 2.5.
