ODEM
To check the 202 tone modem (options -20 and -21):
1.
Make sure the modem is connected to another modem at the other
end of the communications line.
2.
Apply power to the APU and the modem at the distant end.
3.
Place the front panel TEST (test) switch on the APU modem subas-
sembly in the on (down) position. Verify that the front panel CD
(Carrier Detect) LED at the distant end indicates data transmis-
sion activity.
4.
With a dB meter (bridging), check the signal level at the XMT test
points on the APU modem subassembly. Adjust the XMT LVL to
obtain the level required for the application.
5.
Place the front panel TST (test) switch in the off (up) position.
