Diagnostics and Troubleshooting
CTPhone Controller Critical Alarm Relay
When a critical alarm is detected, a relay on the CTPhone Controller is
triggered and LED S3 flashes. The relay activates an external alarm, if one
is installed (see installation instructions and specifications in Figure 3-2 on
page 3-7).
To reset the alarm relay and determine the cause of the critical alarm,
check the critical alarm report in the CTPhone Manager. Checking the crit-
ical alarm report also stops the flashing of the LED.
To view the critical alarm report in the CTPhone Manager:
1 Click on the icon in the CTPhone Manager tool bar.
The Status Window appears.
2 In the Diagnostics menu, select Critical Alarm.
The CTPhone Manager displays the last twelve critical alarms
detected in the Status Window.
Base Station LEDs
The base station has five LEDs as illustrated in Figure 5-1. The four LEDs
on the left indicate error conditions during power on/reset and during the
diagnostic tests that run during normal operation. The green LED on the
right is the power indicator.
