P1-P905, P2-P915 Sensitivity ( db transducers only)
This parameter sets the minimum DATEM level and can be increased to cover a
high noise floor in noisy applications. It is recommended that this parameter not
be changed unless necessary as any echo below the DATEM will be ignored.
Default 5dB (50mV).
P1-P906, P2-P916 Side Clearance (db transducers only)
This parameter sets the distance by which the DATEM trace will be separated from
the raw echo when the DATEM trace covers an echo returned from an undesired
obstruction. Default 0.05m.
System Parameters
Passcode
P921 Enable Code
Enables the passcode (P922), which means the passcode must be entered to go
into program mode. If disabled (set to 0), then no passcode is required, and ENTER
is used to enter program mode. Default =1 (Enabled)
P922 Passcode
This is the passcode that must be used to enter program mode. The default is 1997,
but this can be changed to another value from 0 to 9999.
Backup
P925 Parameter Backup & Restore
This parameter is used to make a backup of all parameters, for example to ensure
a default set is maintained within the unit. If alterations are made to the parameters
that do not work as intended, then the backup set can be restored into the unit.
You can make two separate backup copies if you wish, called backup 1 and backup
2, and restore from either.
