3.3.1
It is important that the Series 4900 Sonar System be well grounded to minimize
potential hazards to the operator and electrical interference from other equipment.
A good ground for the system is a low impedance, well conducted path to sea
water. Always check the quality of the electrical ground by verifying that the AC
power source ground has no voltage potential with respect to the vessel hull.
3.3.2
The main AC power input line is protected by a switch/circuit breaker in both the
Rack Mount TPU and the SonarPro Workstation. The one on the Rack Mount TPU
is located on the front panel on the far right as shown in Figure 3-4 on page 3-16.
The one on the SonarPro Workstation is located on the back panel just to the right
of the AC INPUT connector as shown in Figure 3-3 on page 3-10. To reset a
switch/circuit breaker, switch it to ON.

Towfish Setup

Towfish setup encompasses attaching the stabilizer fins and connecting the tow
cable. Before connecting the tow cable to the towfish, check that the retaining
bolts securing the towfish nose cone and tail cone are tight.
3.4.1
To attach the stabilizer fins:
Using a 17-mm box wrench, loosen the tail cone retaining bolt.
1.
2. Pull the tail cone slightly away from the towfish housing.
Insert the two stabilizer fins into the slots in the tail cone.
3.
4. Tighten the tail cone retaining bolt.
