1. Move the instrument around (e.g. Figure
65
, p.
72
) and observe the display (Figure
64
, p.
71
).
The current dose rate is shown in large digits and as a bar chart.
For best dose rate calculations the source must not be too close to the instrument (Fig-
ure
239
, p.
242
).
You can change the dose rate unit (see
6.31
, p.
159
) and the alarm thresholds (see
6.33
,
p.
161
).
The FLIR identiFINDER R300 continuously compares the radiation to warning and alarm thresh-
olds (see
6.33
, p.
161
). Should the radiation exceed one of the thresholds, the instrument raises an
alarm which is reported on-screen (Figure
66
, p.
72
) and optionally by LEDs, beeper, and vibrator
(see
, p.
for details about the beep and vibration patterns).
You can press
L
Mute
to silence alarm annunciation by beeper and vibrator.
Press
R
Acknowledge
after you took notice of the alarm or warning.
The alarm or warning will be reported in the title bar until the radiation drops below the
appropriate threshold (Figure
66
, p.
72
).

1. Hold the FLIR identiFINDER R300 close to your body so that the neutron detector (Figure

) is close to you (Figure
