SECTION THREE: Setting up the radar
7. Press Heading Calibrate and press the Cursor Pad left and right to rotate the radar image so
that the radar target matches its compass heading on the chart and lines up on top of the
position shown on the chart.
Antenna parking position
When the radar is turned off, the antenna coasts to a stop. If the user wishes to have the antenna
stop at a specific location for cosmetic reasons, the Parking function can be used to control the
stopped position. This function only controls the antenna position at which power to the motor is cut
off. The distance through which it coasts to a stop from this point depends on temperature and wind
conditions. Setting the parking position is entirely optional — it does not affect the operation of the
radar at all.
Setting the parking position is a matter of trial and error: finding the number which achieves the
desired result.
To set the parking position:
1. Press Transmit if necessary to start the antenna rotating.
2. Press Adjust radar... and Setup...
3. Press Park angle and use the cursor pad or keypad to adjust the parking position (between 0
and 90).
The displayed calibration number represents the change from the factory setting. The final setting
that parks the antenna straight ahead will likely be a few degrees left or right from the factory
setting.
4. Press Transmit to stop the antenna rotation and observe its position.
5. As necessary, press the cursor pad to try a new position, and repeat the procedure until the
position is satisfactory.
