Initially display its time as 12:00:00 and software version.
Transmitter checks the position of the switches on the rear of the Transmitter and stores the settings in its memory.
Transmitter sends information to the GPS Receiver and waits for time information from the GPS Receiver. The red LED light flashes until the Transmitter receives a valid time signal from the GPS Receiver.
The time on its front display increments once each second until the GPS Receiver sends the Transmitter a valid time.
The GPS Receiver needs to see three satellites in the sky above before it will send a time signal to the Transmitter. This may take up to 15 minutes for a GPS Receiver that has a 360° view of the sky. The length of time is dependent on the location, weather conditions, time of day. In areas where the unit does not have a full view of the sky, it may take up to several hours for the Transmitter to receive a valid time signal.
The GPS Communication indicator appears when the Transmitter is receiving a signal from the satellite through the GPS Receiver. If the symbol is not displayed, see Troubleshooting.
Once the Transmitter receives a valid time signal from the GPS Receiver, sets its internal clock to the time received and displays the correct time and date on its front display. The Transmitter then begins to broadcast its internal time once every second.
The Transmitter does not broadcast time to system devices until it has received valid time information from the GPS Receiver.
The Transmitter continually monitors the GPS Receiver and updates its internal clock with the time data it receives. If the Transmitter does not receive valid time data from the GPS Receiver for 48 hours, its red LED on the right side of its front display will flash.
The number located on right side of its front display is the channel number to which the Transmitter will be transmitting the time signal. The channel number must be the same as the channel number specified on the site US: FCC/ Canada: ISED license. If not, Primex or an authorized service provider must be notified immediately to adjust the channel to the number that corresponds to the US: FCC/ Canada: ISED license.
The system has a fail-safe design. If the failure of a system component or power loss to a component occurs, all downstream components continue normal operations using their own internal time base. If after a specified period, communication has not been restored, a visual that indicates a loss of communication appears and remains until communication is restored.
Loss of communication visual indicator: Red flashing LED on the Transmitter; flashing colons on LED digital clocks; double stepping of second hand on analog clocks.
