GPS module USER MANUAL February 2017 GPS MODULE – USER MANUAL Instalation and calibration 1. Unscrew the left handset (master) from the head. If there is a reason it is possible to make it on right side. 2. Connect the GPS module to the handset connector and connect the handset on the GPS module and screw it to the head. Attention, longer screws are needed. Longer screws are included. 3. Calibrate the compass – it is necessary to calibrate the compass before first use. It is recommended to calibrate compass after bigger change of location because of different local declination, inclination and magnetic field intensity. 3.1. Remove the head from the canister. 3.2. Run the compass calibration (Setup / Calibration / Compass calibration). 3.3. Select “Start”. 3.4. Rotate the head in all axes until it shows stable values. The yellow column graph start to grow as you are turning the head. Each column represents specific position (octant) of the module and its axes. It is necessary to move the head in all positions to fill all columns. Don’t forget that it includes head down and reverse positions and rotations. When all positions and rotations are completed all graph’s columns change to green. 3.5. When all columns are green the CU starts to calculate calibration coefficients. It takes a while. Please do not interrupt the calibration now. 3.6. When the calculation is finished press “Save”. Setting It is possible to choose coordinate format. Go to Menu / Setup / Preferences / GPS format. You can select your preferred format from DD.DDDDD; DDMM.MMM; DDMMSS.S. 1 GPS MODULE – USER MANUAL Surface mode There is a new screen in surface mode. You can switch to compass screen by pressings of upper button. It shows the compass rose, azimuth and GPS coordinates if available. If the goal is set then it shows the distance and direction to the target point. Compass rose shows current course (white cursor) fixed course (green cursor), opposite direction (orange cursor) course to the target point (arrow in the middle). Compass shows the location of the device, not the handset position. Setting a course Go to Menu / Applications / Set Course – compass start to show fixed course. Clearing a course Go to Menu / Applications / Clear Course. MOB (man over board) Serves as a fast way to save the current position, for example if there is a man over board. The device then guides you using a white arrow in the directional rosette. It also displays the current distance of the device from the saved location and an azimuth. Project point Serves for the navigation to a point using the entered distance in the current azimuth. 1. Point the device in the direction of the required point. 2. Estimate the distance from the point. 3. Select Menu / Applications / Project point. 4. Enter the distance in the respective unit and accept. After you entered the distance and the course, the device will display a white arrow on the directional rosette to the wanted direction. The current distance and the azimuth is also displayed. Set destination Is used to navigating to previously entered coordinates. 1. Pick Menu / Applications / Set destination. 2. Set coordinates in the format (the settings of the format is explained above) and approve. After the assignation of the coordinates, the device will display a white arrow on the directional rosette to the wanted direction. The current distance and the azimuth is also displayed. Dive mode But be advised, The GPS and the functions connected with it will function only on the surface. Only the compass is available under water. There is a new screen in dive mode. You can switch to compass screen by pressings of upper button. It shows the compass rosette, azimuth and GPS coordinates if available. Compass rosette shows the current course (white cursor) fixed course (green cursor) and the opposite direction (orange cursor). Setting a course Go to Menu/ Applications / Set Course. Clearing a course Go to Menu/ Applications /Clear Course. 2 GPS MODULE – USER MANUAL Compass orientation In vertical position of the diver with a tolerance of ±45° from the vertical axis the azimuth is displayed in an axis perpendicular to the vertical axis, in the direction which the diver is facing (fig. A). When in the „trim“ position ±45° the azimuth is displayed in the horizontal axis, in the direction where the diver is swimming (fig. B ). In other position the compass intentionally does not show anything. A A B 45° 45° 45° B 45° 3
