Basic Operation Of The Transmitter; Daylight Saving Time - Primex 14000 Series Installation & User Manual

T
RANSMITTER
The following assumes that the transmitter has been properly set up as described in setup of the transmitter.

Basic Operation of the Transmitter

When power is first applied to the transmitter, the front display will light up and show important information.
Red LED light will flash until the transmitter receives a valid time signal from the GPS Receiver.
l
Display will initially show the time as 12:00:00 and will note the software version.
l
Transmitter checks the position of the switches on the rear of the transmitter and stores their settings in memory.
l
Transmitter then sends information to the GPS Receiver and waits for time information from the GPS Receiver.
l
The GPS Communication indicator will appear when the transmitter is receiving a signal from the satellite through the
l
GPS Receiver. If the symbol is not displayed, see Troubleshooting.
The time on the display will increment once each second until the GPS Receiver sends the transmitter a valid time. The GPS Receiver
needs to "see" 3 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, etc. In areas
where the unit does not have a full view of the sky, due to wall or window installations, building "shadows", etc., this may take up to
several hours.
NOTE:
The transmitter does not transmit time data until it has received valid time information from the GPS Receiver.
Once the transmitter receives the GPS Receiver time signal, the transmitter sets its internal clock to that time and will display the
correct time and date. The transmitter then begins transmission of its internal time once every second. The transmission signal is a
maximum one-watt FM signal at approximately 72MHz. The transmitter continually monitors the GPS Receiver and the transmitter
updates its internal clock with the time data it receives.
NOTE:
If the transmitter does not receive a valid time data from the GPS Receiver for 48 hours, the red LED on the right
side of the front panel will flash.
The number to the right side of the display is the channel number to which the transmitter will be transmitting the time signal.
WARNING: The channel number must be the same as the channel number specified on your FCC/IC license. If not, you

Daylight Saving Time

The transmitter is pre-programmed to automatically make adjustments for Daylight Saving Time.
The letters "DT" (Daylight Saving Time) or "ST" (Standard Time) will be displayed when adjustment for Daylight Saving
l
Time is active (switch #3 in the up position).
If neither "DT" nor "ST" is displayed, then switch #3 is in the down position and the transmitter will not adjust for
l
Daylight Saving Time.
The adjustment to Daylight Saving Time and back to Standard Time take place 2:01 AM on the day of change.
l
NOTE:
The GPS signal does not encode information about Daylight Saving Time. In the spring when the transmitter
changes to Daylight Saving Time, the system clocks will adjust by advancing faster than their normal speed to
make the adjustment and then return to normal operation. In the fall when the transmitter returns to Standard
Time, the system clocks will make the time adjustment and then return to normal operation.

must immediately adjust the channel to the number that corresponds to the FCC/IC license.
