7. Select Monitor > Monitoring > Channel and check that the reciter

is set to the correct channel. If it is, go to Step 8. If it is not, proceed

as follows:

■ Select Configure > Base Station > Channel Profiles and check

that the reciter is configured correctly.

■ Select Configure > Base Station > System Interface and check

that the settings in the Channel selection area are correct. If

external channel selection is enabled, check that no external

equipment (e.g. CTU) is selecting an invalid channel, as this will

result in a “channel invalid” alarm.

■ make sure that it does not interfere with the operation of the

reciter

■ Select Configure > Base Station > General and check that the

default channel is the correct channel required.

■ Check that the digital input switches on the CTU are set correctly.

8. Select Alarms > Current Alarm Status and check for alarms. If there

are alarms, go to Task 3

. If there are no alarms, go to “Visual

Inspection” on page 82.

Note Select Alarms > Reported Alarms to check the alarm history. The

alarm history may indicate which part of the reciter needs further

investigation. You can save these details to a file if required. Note

that the alarm history is erased when the reciter is powered down.
