Picture Freeze
A picture freeze represents a failure to update the User Interface on an
operational display. If a picture freeze occurs the permanent prompt field
will freeze on the currently displayed prompt, or the system data and time if
no prompts are displayed, see Prompts.
If the VisionMaster system includes a PCIO, an alert beep will sound
denoting an internal error, in addition to the prompt freeze. If the system
returns to normal operation then the prompt field will continue to cycle
between prompts and system time, but an internal error alert will be
generated.
In the event of a picture freeze it is advisable to create a system fault report
(for details see Report) and to then restart the system, see Shutdown.
List of Alarms, Warnings and Cautions
The Alerts which are raised by the system, and appear in the Alert Status
Indicator and in the Alerts Display, are given in the tables below, see pages
7-13 to 7-34. The tables list all alerts, and their Priority, either alarm,
warning and caution.
Sensor data types that have been selected for primary navigation in the
CCRS
29
Alert Reporter of the Configuration tool and are currently selected
for navigation will always generate alarms if the data becomes
unusable. For information on the behaviour of other sensor alerts refer to
Alert Behaviour Specific to ECDIS.
Alerts raised on a Client/Server Radar (CSR) system may have different
sets of failure causes from a standard VisionMaster FT. A list of CSR alerts
is provided at the end of the main list.
It should be noted that the set up and configuration of your system will
affect the priority for some Alerts, and whether they are displayed as
Alarms, Warnings or Cautions. These factors include whether or not the
system supports Radar, or Track Control.

Consistent Common Reference System (CCRS) data includes the various types of data that
describe the state of the ship, and which are usually received via sensors. Many of these
types describe a characteristic of the ship itself (for example, the ship's heading, or the
geodetic position of the ship, etc.), while others describe a characteristic of something
associated with the ship, such as `Rudder Angle' or `Propeller Rpm and Pitch'.
