PA REMOVAL AND REPLACEMENT

5.22
See Figure 5 - 27 an follow the procedure to remove and replace UD-51( ) PA.
This is an out-of-service procedure when on a nonstandby
(unprotected) system. On a hot-standby or frequency diversity
system, switch traffic on the channel under test to protect. Use
front panel OVRD controls on AE-37( ) Controller to lock on-
line XMTR (opposite side from failed XMTR) on line.
To prevent monitor point errors, use caution to ensure that
the front panel removed from the PA is replaced on that
same PA. No two monitor point levels labeled on PAs are the
same. Erroneous output levels can result from installing the
wrong front panel and calibrating the PA to the level labeled
on that front panel.
