Service settings
The detector is equipped with a service setting to help in trouble shooting and
diagnostics.
IMPORTANT! The normal operator should not enter this mode.
The service mode menu option is therefore normally not shown in the menu
system and most of the functions in the service mode are protected by a special
password.
IMPORTANT! We strongly recommend that the service mode log in procedure
is kept secret from all personnel not fully trained in the details of all functions of
the detector.
