Figure 2.10 – Front panel of the control unit
The status symbols of the navigation receiver and the battery are
located on the LCD.
The symbol of the navigation receiver status displays the operating
condition of the navigation receiver and that reliable information received from it is
available. If the navigation receiver is off, its status symbol is not highlighted. If the
navigation receiver is on, its status symbol is steadily highlighted or blinking.
Blinking indicates the lack of reliable information from the navigation receiver.
The battery status symbol displays the approximate remaining
battery capacity of the dosimeter. The status symbol consists of four segments. All
segments of the status symbol are highlighted when the battery is full. When the
battery becomes discharged the segments gradually die out. When the battery is fully
discharged all segments are faded.
Two-tone short beeps indicate low battery as well. When the battery is
discharged to the point when the battery status symbol contains only one highlighted
segment, these beeps are generated with 1 min intervals. With further discharge of
the battery when all segments of the battery status symbol are faded such beeps begin
to be generated at a 6 s interval.
The dosimeter battery is charged according to 2.2.6 of the OM.
