Model: 14000 Series Transmitter
This is the toughest issue to diagnose due to there are many variables that can cause a weak signal or symptoms that may lead to indicate there is a weak signal when it's not a signal issue.
The coverage area is determined by many factors. One of the primary factors is the transmitted signal compared to the background interference. For clocks to receive a clear signal from a Transmitter, the signal must be several times stronger than the background interference. Therefore, Transmitters located in areas with generally higher background interference will have reduced signal coverage.
Note
When certain types of electronic light ballasts become defective they may radiate broadband noise, which can interfere with wireless devices. While interference issues are unlikely with the Primex system, high levels of noise present in the 72-76MHz range could potentially cause clocks which are located far from the Transmitter and also within the close proximity of these ballasts to not receive a signal. Very limited instances have occurred in the past, which has only been found to happen when ballasts become defective.
All or some of the below symptoms may be present.
Clocks may not set to the correct time.
Clock issues may increase based on their distance from the Transmitter.
Clock issues may not have a consistent, identifiable pattern.
This may be due to a power issue, a defective Transmitter, interference, wrong size Transmitter for facility, construction of the building, contents of the building, or poor clock maintenance.
Complete all troubleshooting steps, first, see topic Red LED flashing and Transmitter GPS communication symbol is not displayed on front display and work through all troubleshooting topics. Resolve any issues found.
After resolving all issues and the signal coverage is not improved, it's recommended to test the signal coverage. To test use a meter at the Transmitter to check output and/or a meter to test the antenna and cable, or walk the facility with a clock to test signal coverage.
Check clocks to determine if the issue is a maintenance issue, such as weak batteries, or if the issue seems to be only present in a specific clock version or model.
Make a site map. On the map, mark the clocks that have an issue to determine if there is a pattern to the issue.
Correct all issues found while completing all troubleshooting steps.
Correct all issues found with the clocks.
Re-evaluate the situation with a site map and test results of the Transmitter.

Contact Primex Technical Support for additional l assistance when:
It's determined it may be a weak Transmitter.
The Transmitter is operating as expected, but may be too small to cover the facility.
There may be other circumstances causing the issue.
