3.8.2 Performing the Pre-Deployment Checks
The pre-deployment checks should be performed after the system is activated and before the tow vehicle
is deployed. These checks are performed for both the side scan and sub-bottom sonars and involve
verifying that data can be recorded and played back in DISCOVER; rubbing your hand on the side scan
transducer arrays and tapping the sub-bottom hydrophone arrays while observing the Sonar displays in
the DISCOVER Main windows; verifying correct heading, pitch and roll outputs; and zeroing the optional
pressure sensor if installed.
To perform the pre-deployment checks:
1. Activate the system as described in sub-section 3.8.1 .
2. In the DISCOVER 2000-C Dual Frequency Side Scan Main window, click the Transmit tab in the
Lower Control panel. This tab is shown in
F
IGURE
3-6 .

CAUTION! Do not allow the side scan transducers on the tow vehicle to
continuously transmit in air for an extended period as damage to the
transducers could occur.
3. Select the High Sonar On and Low Sonar On check boxes.
The side scan transducer arrays on the tow vehicle should begin transmitting and data should
begin scrolling on the Sonar display in the DISCOVER 2000-C Dual Frequency Side Scan Main
window.
4.
Record a few minutes of data and then play back the data and verify that data can be recorded
and played back.
5. Rub the port and starboard side scan transducer arrays while observing the Sonar display in the
Main window.
You should observe streaks or noise spikes in the waterfall display.
