If the consistency checks pass, the operator is prompted to store the parameters in non-
volatile EEPROM. A ‘No’ response returns to the Deployment menu for further parameter entry.
A ‘Yes’ response stores the parameters and runs the Diagnostics routine, including the 10 V and
7.5 V battery warning checks.
The final prompt is ‘Proceed with the deployment (Yes/No) [N]?’ This option starts the
deployment.
Parameter Range Check
The parameter range checks verify that each of the deployment parameters is within its
allowed range. If a range violation is detected, the operator is prompted to change the parameter
and then returns to the deployment menu.
Schedule Check
When all of the deployment parameters are within the specified ranges, the firmware
performs a profile consistency check on the proposed schedule. The consistency checks begin
with the calculation of the minimum profile duration (MPD) where:

DPL = Deep Pressure Limit [dbar]
SPL = Shallow Pressure Limit [dbar]
NPS = Nominal Profiling Speed [dbar/sec]
SLBP = Sensor Logging Before Profiling [sec]
SLAP = Sensor Logging After Profiling [sec]
DGR = [byte/sec]
DTR = Data Transfer Rate [byte/sec]
