"ALARM" LED informs about the presence of an alarm condition. If
measurement results exceed the alarm threshold levels it is blinking at 4 Hz
frequency. Blinking is accompanied by a two-tone audible signal.
"CHARGE" LED displays the progress of the dosimeter battery charging.
Possible statuses of the "CHARGE" LED are shown in Table 2.2 (2.2.6.5 of this

2.3.3 Controls of the dosimeter
2.3.3.1 The dosimeter is regulated with the help of four buttons (4), (5), (6),
(7) according to Figure 2.10.
2.3.3.2 Each button is responsible for different functions depending on the
mode of the dosimeter's control unit, time of holding the button down and a status
of the (5) Fn button.
2.3.3.3 The names of the functions are printed near each button. The names
are printed in two colors: white and yellow. White color is responsible for the
functions that the button performs if it is the only one button pressed right now.
Yellow color – if Fn button was pressed and held down before it was pressed (5).
2.3.3.4 To describe the user actions the operating manual will use the function
names to be done by the button. For example, if it is written, "shortly press LIGHT",
it means that you should shortly press button (6). And if it is written: "Shortly press
SOUND", it means that you should press (5) Fn and while holding it down shortly
press button (6).
