TEST PROCEDURES
1.6 Connect the AC line cord to the back of the amplifier and the AC source. Turn on the amp-
lifier at the AC power switch, located at the back corner of the amplifier near the AC power cord
connection. Click START twice in the SCAN BARCODE dialog box. This will begin the LUAP test
on the station. Note: There will be several dialog boxes that will open during the course of the
test. The test operator will need to perform the action in the dialog box to keep the test running.
Important Note: The PM8500 amplifiers require a dedicated 20 Amp AC line to power the unit
during test. Failure to connect the unit to a dedicated 20 Amp line could result in LUAP test
failures due to line voltage sag.
1.7 During the test, the VERIFY

dialog box will open, as shown at
right. Check that all of the cables
are properly connected and that
the AC power switch on the unit
are on. Click OK. The test will
resume.
Next the unit’s firmware and
speaker EQ versions will be
checked. If they need to be up-
dated, the test will fail, as shown at
right and below right, and you will
need to update the firmware and
speaker EQ’s using the
