4.4.1 Calibration
NOTE
Ensure transponder is in standby while doing calibration.
Each time the TRC, directional antenna, or any of the directional antenna cables (including connectors)
have been repaired or replaced the TRC must be calibrated. Calibration is accessed by selecting that option
from the Service Menu (i.e., press SELECT with Calibration high-lighted). The initial calibration screen
(see figure 4-2) shows the current calibration value in degrees. Calibration can be performed with the
terminal device by using the Cal command.
NOTE
If the TRC has never been calibrated, the current calibration value will be displayed as 999.

After a successful calibration, both old and new calibration values will be displayed (as shown in
figure 4-3). Press EXIT to return to the Service menu. Soft-keys (2), (3), and (4) are not used.
