Scroll LCD setting  
You  can  choose  to  allow  the display  screens  to  scroll  through  as 
described above or you can select to switch off this function and step 
through the displayed dosimeter screens one by one manually.  
dB Alarms setting  
You can choose to enable or disable the high intensity blue  flashing 
LED when the measured noise levels exceed the set threshold trigger 
levels  chosen  in  the  Casella  insight  data  management  software  (or 
dB35) configuration setup. For further details see section 5.8. 
Pre-set Mode (Run Duration Timers)  
This mode allows a variety of settings from Off through to 12:00 in 30 
minute  steps  by  pressing  the  left  button  to  show  the  value  required 
and then pressing the right button to accept and move on to the next 
menu  item.  Press  and  hold  in  the  left  button  to  change  through  the 
selections  more  quickly.  The  run  will  start  and  run  for  the  selected 
fixed duration time chosen in this menu. 
Auto Lock  
This choice is off by default but allows the user to lock the unit during 
the run to prevent the display from showing any run information other 
than  the  run  time  and  battery  condition.  The  lock  function  can  be 
switched  on  and  off  during  a  run  by  holding  the  right  button  in  and 
pressing the left button three times in succession quickly. This allows 
a  supervisor  to  inspect  the  run  results  so  far  at  any  time  during  a 
typical day‟s measurement in the field. 
Clear memory setting  
You  can  choose  to  leave  any  runs  in  the  memory  or  to  delete  them 
manually prior to beginning new measurements with this control. This 
may be needed before starting a series of long runs before being able 
to download to the computer program. 
When  on  the  clear  memory  screen,  the  memory  can  be  cleared  by 
first pressing the „L‟   key to change the „No‟ option on the screen to 
„Yes‟.  Then  press  the „R‟    key  to  confirm.  A  second  screen  will 
appear  requesting  confirmation  that  you  wish  to  delete  the  memory. 
Use  the  „L‟    key  to  change  the  option  to  „Yes‟ and  if  you  wish  to 
delete the memory press „R‟   to confirm. 
Once all the options within the configuration menu have been set, the 
display will return to the standard screens as described in section 5.
