Testing the System Installation
After you have completed the installation of the control head, transducer,
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. Thorough testing should be performed with the boat in the water;
however, you can confirm basic operation initially with the boat out of the
water as well.
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 chirp 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
900 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 grey 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.
