Compass Alignment
To align Weather Transmitter WXT510, proceed as follows:
1.
If WXT510 is already mounted, loosen the fixing screw on the
bottom of the transmitter so that you can rotate the device.
2.
Use a compass to determine that the transducer heads of WXT510
are exactly in line with the compass and that the arrow on the
bottom of WXT510 points to the north.
3.
Tighten the fixing screw on the bottom of the transmitter when the
bottom arrow is exactly aligned to north.
