(either directly or by calculation) will show three dashes instead of the
digits, until the data is received again. If the data is normally available
from both SeaTalk and NMEA connections, and only the SeaTalk data
is absent, then the NMEA data will be used after 30 seconds.
If position data is lost, but speed and direction are still available, then
after 30 seconds the RayData will calculate the position by dead
reckoning, and indicate that this is the new data source.
7.4 Self Test Mode
Self Test Mode provides a simple means of testing the lighting, LCD
display, keypad and transducer interface.
To enter Self Test Mode:

together.
The RayData then displays the following:
1. The software version number and serial number for five seconds.
2. The detection status (Found or Not Found) of the Depth, Speed and
Temperature transducers.
3. A test pattern sequence.
While the test pattern is displayed, the display and key lighting cycles
repeatedly through all levels: off, low and high for the display, and low
and high for the keys. Three short beeps are generated if you press any
key during self-test.
To exit self-test, press NAV and

7.5 Factory Reset
The system defaults can be changed using the Setup pages, as
described in Chapter 4. If you have problems with the setup changes
you have made, you can revert to the original default settings by
performing a factory reset.
In addition to resetting the Setup values, the factory reset returns all the
alarm settings to the defaults listed in Chapter 5, resets the log, and
resets the lighting and contrast levels to their normal levels.
To reset the system, press the

screen is blanked, and “RESETTING IN 5” is displayed. This shows the
seconds before the system resets, and the number counts down.
