If you have any of these problems, follow the appropriate steps:
1. System controller appears off (LCD dark) when power is connected:
• Disconnect power and remove top cover. Check fuse and replace if necessary.
2. Wireless analog clocks not synchronized with system controller:
• Verify the System Controller is transmitting. TX should be displayed on the LCD screen every 30 seconds, unless the System
Controller is in Quiet Mode. Reference Appendix J for more details on Quiet Mode.
• If your system has an external transmitter, check all cable connections (also check the data cable and pins for damage) and verify
the PTT and DATA LEDs are lit on the external transmitter when TX is displayed on the System Controller.
3. System Controller is not transmitting:
• If TX is not being displayed every 30 seconds:
-Ensure system Controller is not in Quiet Mode. Reference Appendix J for more details on Quiet Mode.
-Ensure TX window is off (Reference "Settings and Configuration" Step 2).
-Press
145 and ensure TX ON is displayed. IF TX OFF is displayed, press 145 again.
-If your system has the campus antenna kit, it may have been hit by lightning, even if there are no visible signs of damage to the
system equipment. If this is the case, the signal coverage will be greatly reduced and the system clocks may not be able to receive
the signals from the transmitter. The lightning arrester (item D shown in "Campus Transmitting Antenna Installation" section)
contains a gas discharge tube which is designed to protect the transmitter and attached equipment from lightning damage. There
is no visible way to determine if the gas discharge tube is good or not. The only way to check the gast tube is to use
an Ohmmeter. If the unit is bad, the Ohmmeter will show a "Short". If the unit is in good condition, it will show a high
resistance. A replacement discharge tube is available from the manufacturer, or the entire lightning arrestor (ATS part #H003491)
can be replaced by contacting American Time.
4. Power has been reset, Press OK is displayed on the LCD screen:
• Verify that the power source is stable
-Press OK if there was a power outage
-Press OK if power is not supplied by a switchable plug
-Press OK if unit was unplugged
• Determine source of power loss
5. Unit Crashed. Press OK is displayed on the LCD screen:
-The system controller will automatically reset and resume normal operation if the unit crashes.
-Diagnostic information is saved to the unit for troubleshooting.
-If this occurs frequently, please update to the newest firmware, as the issue may have already been resolved.
6. Incorrect time is displayed by system controller after loss of power:
• Backup battery may be dead. Check for "Low Battery Voltage" message when time is displayed in small text (see Display Settings
section). If this message is displayed, replace battery with new CR2032 or equivalent 3v lithium battery. Install battery with +
side up, as shown below.
7. Power outage during Daylight Saving Time correction:
• If there is a power outage during the correction period for Daylight Saving Time, the secondary clocks might not correct. In this
case, the clocks can be reset manually (see Clock Troubleshooting) or they will automatically reset during their next reception
attempt after the power is restored.
7. Signal circuits not responding to programmed events:
• Refer to Wired Signal Circuit Troubleshooting Guide.
8. Unable to synchronize with Ethernet Time Source:
• Refer to the Ethernet Troubleshooting Guide.
9. Unable to synchronize with GPS Time Source:
• Refer to the GPS Troubleshooting Guide.
10. Unable to synchronize with CDMA Time Source:
Refer to the CDMA Troubleshooting Guide.
11. Lost or forgotten User Lock:
• Contact American Time Technical Support at the number listed below.
12. SiteSync IQ System Controller locks up or display goes blank:
• Use a pen, small screwdriver or paperclip to press the reset button (See diagram in Appendix G).
OR
• Remove power from the unit by switching the Power Input switch off, wait 5 seconds, then turn the unit back on.
If the problem cannot be resolved after following these steps, call Technical Support at American Time at 800-328-8996.
