Chapter 1. Special Functions
Special functions available on the ST30 Bidata are:
1.
Calibration lock/unlock
2.
Boatshow mode
3.
Damping
For security reasons, extended calibration features are selected by an
extended hold (14 seconds) of
a
and DEPTH until CAL is displayed for the
second time, followed by momentary depression of both the SPEED and
RESET
keys.
To cycle the features, press the DEPTH key until the required option is
displayed.
1.1 Calibration Lock/Unlock
Calibration lock/unlock eliminates the risk of accidentally changing all but the
extended calibration values.
This feature is particularly useful for operators of charter boats who spend a
great deal of time tuning the pilot to the vessel, only to find a customer alters
the settings at a later date.
This feature is displayed as C1 or C0.
C1 = unlocked (normal access)
C0 = calibration is locked (no access).
The mode is changed by pressing the RESET key.
Calibration lock/unlock is stored by pressing
a
and DEPTH for 2 seconds.
1.2 Boatshow Mode
Boatshow mode (S0 = disabled, S1 = enabled) is a demonstration
programme to show the features of the instrument.
The mode is changed by pressing RESET.
Note: Boatshow Mode automatically resets to normal mode if a transducer is
connected directly to the instrument or if the instrument is powered down.
However, boatshow mode can be stored by:
1.
Setting the instrument to repeater mode
2.
Selecting Boatshow Mode
3.
Exiting from repeater mode
