Alarms
When the Repeater is in Test mode the safety
measures are disabled. Therefore, if the Repeater is
keyed for an extended period and the power amplifier
temperature increase, thermal shutdown will not occur.
There are pop-up windows that appear in the Test
mode screens to alert the user that there is an alarm
and action should be taken. Refer to Figure 1-3 for an
example of this type of alarm.
