GREEN LED = System Ready
The GREEN System Ready LED lights up solidly, and remains on, when the system is ready to run.
On startup, the GREEN System Ready LED is off while the system performs power-on self-tests. If
any of these self-tests fail, the GREEN System Ready LED remains off. If all self-tests pass, the
GREEN System Ready LED lights up and remains on. Since these power-on self-tests also test the
Tow Vehicle interface, the Tow Vehicle must be attached to the 3100-P Portable Topside for these
power-on self-tests to pass.
If the GREEN System Ready LED never lights up, but stays OFF permanently, check the Tow Vehicle
cabling. If a problem is found and corrected, then cycle power to run the power-on self-tests
again.
YELLOW LED = Ping
The YELLOW Ping LED lights up during startup to indicate that the system is initializing. After the
system has initialized the yellow light turns off. The YELLOW Ping LED flashes while the 3100-P
Topside is pinging (sonar transmitting). The flashing rate of the YELLOW Ping LED does not always
match the actual ping rate (this is normal behavior).
If the YELLOW Ping LED never lights up during startup or pinging, but stays dark permanently, the
most likely cause is that the YELLOW Ping LED or its own circuitry is faulty, in which case the rest
of the system might still be fully operational.

Pre-Deployment Tests
Pre-deployment checks should be performed
before
the tow vehicle is deployed and
after
the system is
activated. Pre-Deployment checks involve:
1.
Listening for the transmitted pulses from the transducers on the tow vehicle
2.
Tapping the fiberglass shell with a hand or, gently, with a screwdriver handle near the hydrophone
arrays while observing the Waterfall Display in DISCOVER, ensuring it plays back and navigation is
present. DISCOVER is shown in
. An example Tap Test is shown in
NOTE:
See EdgeTech DISCOVER Sub-Bottom software manual, 0019800,
for additional software information.
