Weak Signal And Limited Coverage Area - Primex XR Series Troubleshooting Manual

Weak signal and limited coverage area

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.
Symptoms
All or some of the below symptoms may be present.
l
Clocks may be displaying a visual signal loss indicator due to they have not received a time update for three days; Analog
Clock second hand is stepping and a Digital Clock/Timer colon is flashing.
Clocks may not set to the correct time.
l
Clock issues may increase based on their distance from the Transmitter.
l
Clock issues may not have a consistent, identifiable pattern.
l
Cause
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.
Analyze
1. Complete all troubleshooting steps, first
(section 1)
and work through all subsequent troubleshooting topics. Resolve any issues found.
2. After resolving all issues and the signal coverage is not improved, it's recommended to test the signal coverage.
