Recommended Actions:
1. Check to make sure that there is a CEPT-1 connection present on either of the connectors
(BNC) for the channel in alarm.
On a multiple-capacity radio, if the alarm is on a channel which is
unused at this time, the alarm condition can be disabled by a rear
panel DIP switch, as described in Section 3.12.4.
4. Verify that the CEPT-1 line has data active at the radio connection. This can be
accomplished using a BER tester or signal analyzer. Also, signal activity can be verified by
using an oscilloscope.
5. Verify that pin connections have been made properly (in accordance to Section 3.11). Make
sure that you have connected the CEPT-1 with respect to the transmitting device.
6. Connect a BER tester or signal analyzer to the CEPT-1 Monitor INPUT port on the rear
panel.
