Solution
Physical problem related to the detection circuit and
detectors (optical check)
Contact Mirion for verification.
Physical problem related to the detection circuit and
detectors (no pulse during the last check period)
Physical problem related to the detection circuit (no
communication with the microprocessor)
Problems accessing the data saved in memory
Problems accessing the data saved in memory
Problems accessing the software program saved in
memory
Problem with the parameters' data integrity saved in
memory
Pulse counting limitation due to an amount of mecha-
nical shocks on the detection circuit
Confirm whether or not this fault occurs with "normal use"
(no high mechanical or electromagnetic stress).
Contact Mirion for verification.
Electrical problem related to the speaker circuit
Verify that the speaker cavity is not obstructed and the
battery voltage is not too low (low battery fault).
Contact Mirion for verification.
