Test Function - This function is only to be activated by qualified service engineers. Toggle TxPower - This function is only to be activated by qualified service engineers. Test Beam - This function is only to be activated by qualified service engineers. Echo Level - This button provides a readout of the current noise in the waters surrounding the vessel. This noise is caused by air bubbels, water flow and mechnical disturbances from hull and engine. In order to obtain the besst possible sonar result, the noise level readout should be as close to 0. 0 dB as possible. Roll - This is not a button, it is a readout from the sensor of the actual roll value at the time of the last transmission. Pitch - This is not a button, it is a readout from the sensor of the actual pitch value at the time of the last transmission. TRU Temp- This button provides a readout of the current temperature inside the Transceiver Unit. If the temperature rises to unacceptable levels, and alarm will be given. Interpolation - This is a built-in software function that may give a more realistic presentation of the echos. Message bar - This button opens the Message bar parameter dialogue, which allows you to monitor operational messages from the sonar. Installation menu - This button opens the Installation menu on the top of the display.

[. . . ] The motor will automatically stop when the transducer shaft reaches the upper or lower limit switch. Remember to set the switch back to Remote position when finished. Hoist/lower contactors K301 and K302 If the 3-phase voltage for the hoist/lower motor is available, the transducer can be hoisted and lowered by operating the hoist (K301) and lower (K302) contactors in the Motor Control Unit by activating the small switch handle on the front of the contactor. Warning The switches must be released before the transducer shaft reaches upper or lower position, as this operation overrides the two limit switches. Manual hoist and lower operation If the 3-phase voltage is not available, the transducer must be hoisted and lowered by means of the hand crank. Locate the motor overload switch S301 in the Motor Control Unit, and press the red button marked 0. [. . . ]
