Anytime you replace a subassembly that you think is faulty, you will
have to repeat the test that indicated that particular subassembly was
faulty.
If that test then gives you a normal indication, you know the
subassembly was indeed faulty.
If the test still gives you an abnormal
indication, you know that you have a fault elsewhere.
10. Read paragraph 3-4 of the TM extract to review some of the main points
that you have covered. Then, proceed to the next step.
NOTE:
If a fault continues to exist after module replacement, proceed
with module-by-module substitution until the fault is corrected.
11. Ask your training supervisor for a radio that contains a faulty
subassembly. Discuss, with the training supervisor, any problems you might
be having. When you have the radio, troubleshoot it to find the defective
subassembly and then continue with the next step.
12. What subassembly did you find to be faulty?
Tell the training
supervisor what you found.
It should agree with the fault the training
supervisor put in.
13. Ask the training supervisor for another radio with a defect.
You
should keep asking the training supervisor for defective radios and
troubleshooting them until you feel confident of your ability. You should
troubleshoot at least five radios to gain experience.
Remember, the
training supervisor is willing to help you should you need help. Work at
your own pace and take a break when you need one.
14. Are you able to perform direct support troubleshooting on the R-1496(
)/ARN-89( )? If your answer is YES, you should tell the training supervisor
you are ready to take the performance test on Task 1. If your answer is NO,
you should practice more and discuss any problem areas with the training
supervisor before asking for the test. Let's take a look at what you have
learned in Task 1.
15. During this lesson, you have learned the correct procedure to follow
in troubleshooting the R-1496( )/ARN-89( ) at the direct support level.
a. You learned to observe safety precautions to protect both yourself
and the equipment.
b. You
learned
to
set
up
your
equipment
for
the
basic
test
and
subtests.
c. You learned to follow the right troubleshooting procedures.
