This is an indication that the fibre optic cables are damaged. Check all cables (Section 7.2: P99) and
replace or repair. There are also short fibre optic cables located inside the transmitter and receiver that
may be causing the problem (see item K in Figure 9-1). Before attempting to clean or replace these cables,
contact Sensors & Software (see below).
7.9 System Runs But Data Does Not Look Right
There may be cases when the system does not actually fail and cause error messages but the data being
collected does not seem “right”, because of perhaps excess noise, banding or very weak signals. The best
way to determine whether the strange data is a result of local conditions in the survey area or real problem
with the system is to, shortly after receiving the system and periodically afterwards, collect a test line of
data at a designated location (Section 6.9: P90). Then, suspected system problems can be confirmed or
dismissed by collecting data on the test line and comparing it to earlier data collected along the same line.
