Important Information 
The  unique  DATEM  software comes  into  operation  as  soon as  power  is 
applied  and  is  designed  to  monitor  a  moving  level  or  target  with  the 
transducer in a fixed position. 
If,  after  any  period  of  use,  it  should  become  necessary  to  move  the 
transducer, for any reason, from its original operating position, switch off 
the Ultra 4, before proceeding, to prevent any undesirable updates to the 
DATEM trace. If after moving the transducer the reading is not as expected, 
please refer to Chapter 10 Troubleshooting.
