This <strong>ACU</strong> has been factory tested for electrical<br />
performance including return loss, gain, and<br />
RET communication<br />
In the event of a system error message, it<br />
should be isolated from the BSA radio and retested<br />
again (before RMA / DOA process is<br />
started).<br />

<strong>ACU</strong> <strong>Quick</strong> Test <strong>Guide</strong><br />
Use to validate a possible field failure. RFS recommended<br />
trouble<strong>shooting</strong> hardware is required. If this process indicates a<br />
valid failure, product should be replaced. On any Antenna/<strong>ACU</strong><br />
(RET Motor) failure based on OSS indicators, Isolate the Antenna<br />
from the complete radio system and attach to the <strong>ACU</strong> (RET motor)<br />
using an RFS Protocol adapter and AISG cable.<br />
Then, using a computer running RFS NEM-ALD-A software (rev<br />
3.2.1 or newer) follow the remaining test process steps.<br />

Based on the following screen shot, verify the following:<br />
o Is the “Antenna Model Number” that of the antenna<br />
it’s attached to? If not, use “Antenna Configuration<br />
Data” to select antenna model and “Set” to update.<br />
o Is the <strong>ACU</strong> model number correct (<strong>ACU</strong>-A20-N)? If<br />
this is not correct, the <strong>ACU</strong> will need to be returned<br />
via RMA to RFS.<br />
o Is the status indicator GREEN?<br />
“Alarm List” tab to identify alarm.<br />
If RED, check<br />
o Is the software version 2.52? If incorrect, use RET<br />
software download (9600 baud) to upgrade to<br />
correct version.<br />
Execute the “Self Test” under the AISG commands<br />
section. If the system returns “Self Test was<br />
successfully executed”, then the <strong>ACU</strong>/Antenna is<br />
likely OK and the fault is somewhere else in the<br />
system other than the antenna/ret combination. If the<br />
Self Test fails, the material should be returned for<br />
replacement. Include this check sheet as support for<br />
the RMA.<br />
Upon completion of this checklist, if all tests are<br />
indicating OK then the <strong>ACU</strong>/RET motor (and antenna)<br />
should be returned to operation, as the system fault<br />
is located somewhere other than the <strong>ACU</strong>.
