The 14000 Series Transmitter front display provides important information and indicates its current operating status.

Component |
Description |
---|---|
Time |
Displays the precise time received from GPS Receiver. If AM or PM is on the display, then 12-hour option is selected. If neither AM nor PM is on the display, then 24-hour option is selected. |
Daylight Saving Time |
The letters "DT" (Daylight Saving Time) or "ST" (Standard Time) displayed when adjustment for Daylight Saving Time is active. If neither "DT" nor "ST" is displayed, then switch #3 is in the down position and the Transmitter will not adjust for Daylight Saving Time. |
GPS Communication |
GPS Communication indicator The parentheses |
Day/Date |
Displays the day and date received from the GPS satellite. |
Channel Number |
Displays the channel number (1-16) the Transmitter is set to. |
Red LED |
The red LED (light emitting diode) is located on the right side of the front panel of the Transmitter. The LED flashes on initial setup until a GPS time signal is received. The LED flashes when no time data has been received from the GPS Receiver in 48 hours. See the Troubleshooting section for additional information. |
The status of the GPS Receiver is indicated by the GPS communication indicator.
When the Y like symbol
is displayed, the GPS Receiver is connected to the Transmitter and there is communication between the GPS Receiver and the Transmitter.
When the Transmitter is receiving valid time data from the GPS Receiver, the three parentheses
sequence in a motion pattern. If these symbols are not displayed, see Troubleshooting.
The Time Zone is not shown on the front display. However, when the Transmitter has received a valid time from the GPS Receiver, the correct Time Zone can be checked by verifying the correct hour is displayed. The Transmitter can be set for all 24 time zones around the world and 1/2-hour time zones.
The front display of the Transmitter displays the precise time received by the GPS Receiver.
The time displayed may be in 12 or 24-hour format, which is set by the 12/24-hour switch setting on the back Transmitter. The switch setting only sets the time displayed on the Transmitter front display, and does not affect the system devices. If AM or PM is displayed, the switch setting is set to 12-hour. If neither AM nor PM is displayed, the switch settings is set to the 24-hour.
Analog Clocks are all 12-hour clocks.
Digital Clocks have a selectable jumper option to display either 12-hour or 24-hour time regardless of the Transmitter 12/24 option setting.
The Transmitter is pre-programmed to automatically make adjustments for Daylight Saving Time shifts.
The letters "DT" (Daylight Saving Time) or "ST" (Standard Time) is displayed when adjustment for Daylight Saving 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 does not adjust for Daylight Saving Time.
The adjustment to Daylight Saving Time and back to Standard Time take place 2:01 AM on the day of the DST shift.
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 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 make the time adjustment and then return to normal operation.
