Here is a breakdown on each of the menu options:
• Background – This determines the dose rate level when there is no source present.
This is used to create an environment with a constant dose rate level.
• Alarm – This Alarm determines the dose rate level to which any great increase in
dose rate will trigger an audio alarm. This alarm will have a frequency of 1 tone every
second.
• Sound – This determines the initial audio state of the device upon turning on.
• BCKL – This determines the initial LCD backlight state of the device upon turning on.
• Network – This determines the network type of this instrument. There are two states:
Master and Slave. The Master instrument will control the addition of any new
instruments into the Radiation simulation network. There must always be one Master
instrument switched on to control this network. The Slave units do not have this
controlling function, but will join any radiation simulation networks upon turning on.
(This radiation network technology is common to all SAFE-Series instruments.)
