7. If you need to pair another transmitter, follow the procedure from the step 3.
8. To finish the regime of pairing – coding press the button
Note: To delete one of the paired transmitters (collars) from the receiver memory,
perform pairing without switched on transmitter. After about 10 seconds, there will

7.5 Digital compass calibration

To display accurate direction to the transmitter collar, it is important to perform the
calibration properly. If the device does not show correct direction even with maximum
precision GPS (2 lines on both signal indicators GPS on the display), it has not been
probably calibrated for long time or has been calibrated incorrectly.
WARNING: Always perform calibration outdoors, away from objects that emit
magnetic fields - buildings, cars, overhead and underground power lines.
Starting calibration
If you know the direction towards to the magnetic north, you can go directly to second
step.
1. Press simultaneously two bottom buttons
calibration. Then step by step rotate the device around each of the three axes
(picture no. 1, 2 and 3). To finish calibration press the back button. For more accurate
calibration, continue to step 2.
2. Using the compass on the display, look up the north and turn the receiver so that the
antenna faces the north (picture no. 4). Press simultaneously two bottom buttons
and for 2 seconds - to start the calibration.

3. Still facing the north perform a minimum of 10 rotations as on the picture no. 5 and
no. 6. For quality calibration the each individual rotation should be carried out with
little deviation from the north direction (picture no. 7). The slower and more turns
you make, the better will be the calibration. To finish, press the back button
