The Store/Recall menu is used to store single display pictures or a sequence or pictures. The stored pictures can easily be recalled for evaluation or comparing schools. Store/Recall parameters Store - This is the "record" button to start the storage sequence. Print - Allows you to print the stored picture to the default printer (if any). The following other parameters are available: Store, page 140 Store Mode, page 140 Recall, page 128 Recall Mode, page 128 The Close button closes this menu. The Help button opens the on-line help. 850-164511 / Rev. E 67 Simrad SP90 System test The System test menu is activated by the Test button in the Setup menu. The System test menu provides several test routines available to perform operational and functional tests. These tests are designed only to be carried out by qualified service engineers. Test parameters Test Configuration - This function is only to be activated by qualified service engineers. 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. [. . . ] Set the switch to STOP to position the transducer at any vertical location. Marine growth must be carefully removed with fine-grade sandpaper or emery paper. Note The transducer surface must not be painted. 164 850-164511 / Rev. E On-board maintenance Hoist motor overload protection To prevent the hoist/lower motor from overload, an overload circuit breaker S301 is located in the Motor Control Unit. This may automatically be switched off during hoisting if the vessel's speed is too high, or if the transducer shaft has been bent. To reset the motor overload switch, open the Motor Control Unit, locate the switch S301 and press the button marked 1. [. . . ]
