Testing the System Installation
After you have completed the installation of the control head and any other accessories such as the GPS
receiver, and have made all the cabling connections required, you must test the installation before using
the system.
To test the installation:
1. Press the POWER/LIGHT key on the control head once to turn on the control head. (There will be
an audible sound to let you know that you pressed the key, and the initial Title screen will appear.)
If the unit does not power up, make sure that power is available. While the Title screen is shown
on the display, press the MENU key to display the Start-Up Options menu. Use the UP or DOWN
4-WAY Cursor keys to position the cursor, then the RIGHT Cursor key to select System Status from
the Start-Up Options menu (see the Start-Up Options Menu section for more information about
these menu choices). The System Status Self Test screen will appear.
NOTE: If you wait too long, the system will default to whichever menu mode happens to be highlighted, and you
will have to start again.
2. Self Test displays results from the internal diagnostic self test, including unit serial number,
Printed Circuit Board (PCB) serial number, software revision, total hours of operation and the
input voltage. See System Status for more information about the Self Test.
3. From the System Status screen, view accessory connections by pressing the VIEW key. See
System Status for more information about the Accessory Test.
NOTE: The speed will be detected only if the paddlewheel has moved since the 1100 Series™ has been
powered up.
4. From the System Status screen, see a GPS Diagnostic View by pressing the View key. GPS
Diagnostic View shows a sky chart and numerical data from the GPS receiver. The sky chart
shows the location of each visible GPS satellite with its satellite number and a signal strength
bar. A dark gray bar indicates that the satellite is being used to determine your current position.
A light gray bar indicates that the satellite is being monitored, but is not yet being used. See
System Status for more information about the GPS Diagnostic View.
5. You are ready for on the water operation.
