If the Spectracom Clock's power LED is off, it indicates the unit isn't receiving power. First, check that the AC power is live to the power adapter and that the adapter is properly plugged into the unit. Also, ensure that no connecting cables are pinched or shorted. If the issue persists, try replacing the power adapter.
What to do if Spectracom Clock is flashing red?
A flashing red light on your Spectracom Clock indicates a fault with the GPS antenna. This usually means there's a short or open circuit in the GPS antenna cable. Verify that the antenna is securely connected. Use a multimeter to check the continuity of the cable, ensuring there are no open circuits or shorts.
Why is my Spectracom Clock showing a yellow light?
A yellow light on the Spectracom Clock means it's no longer tracking satellites and is not in hold-over mode. You may need to check the GPS reception following the instructions in the corresponding section of the manual. If the modem dial-out is enabled, verify modem operation, as the modem should have prevented this.
What to do if the Sync LED is not lit on my new Spectracom Clock?
If the Sync LED on your newly installed Spectracom Clock isn't lit, it might be because the unit hasn't had enough time to establish a connection, or it's unable to track satellites. If it's been less than 20 minutes since you powered it on, keep monitoring it. If it's been longer, you may need to check the GPS reception following the instructions in the corresponding section of the manual.
What does flashing green mean on my Spectracom Clock?
A flashing green light on the Spectracom Clock usually indicates that the unit is synchronized via the optional dial-out modem. If you are not using the optional dial-out modem, you may need to check the GPS reception following the instructions in the corresponding section of the manual and review the Alarm and Qualification logs.
