If possible, it is best to keep the tow cable connected to the towfish while on deck.

If the tow cable is disconnected, however, it is very important that all connectors

be properly maintained. Connectors must be kept clean and must remain out of the

way of traffic while on deck. Klein Marine Systems supplies dummy connectors

which can be used to protect the underwater connectors on the towfish and the tow

cable when they are connected.

or damage to the towfish or the SP-II TPU electronics, or to both. To turn off the

SP-II TPU, switch the A/C-D/C switch to OFF. For the location of this switch, refer to

"Operator Controls and Indicators" on page 3-11.

To disconnect the tow cable:

Verify that the SP-II TPU is off and that its AC and DC power cords are

disconnected.

2. Grasp the body of each connector at the towfish and gently pull them apart. Do

not pull on the cables to separate the connectors. Always hold the body of the

connectors. After separating the connectors, put a thin coating of silicone grease

on the rubber section of the connector pins.

3. Remove the retaining ring from the tow pin and withdraw the pin. Disengage the

tow cable shackle from the towfish or tow bracket. Replace the tow pin in the

hole in the tow bracket, and secure it with the retaining ring.
