2.3 XR Transmitter Operation

2.3.1 Scope

This manual defines the operation of the XR transmitter with case-attached whip antenna. It does not include the
operation of the following:
•
High power transmitters or transmitters with external antennae.
•
Clocks, timers, repeaters, or switches.
•
The XR server or any of its software.
o The network connection process for the transmitter to the server.
•
The Compusync switch or software.
•
The Scheduler software for bell schedules or transmitter intermittent operation schedules.

2.3.2 Power Up Sequence and the Front Panel

Once power is applied, the three LEDs on the front panel shown in Figure 3 in Section 2.1.2 will all light up for
approximately two seconds. After that, they will operate as follows:
•
Green LED.
o Off when the transmitter is waiting to be synchronized or the output power amplifier has failed.
o On when the transmitter is broadcasting.
o Off when the transmitter was in a blinking green situation and power is cycled.
o Flashing when the transmitter is disabled by the server or an internal schedule for intermittent operation
•
Yellow LED.
o Off means the transmitter is synchronized with a time source correctly.
o Flashes when the XR transmitter has not received valid GPS, Repeater, or NTP time for 48 hours or at
initial power up until synchronization occurs.
•
Red LED.
o Off means there are no errors recorded in the internal error log.
o Flashing means there is an error recorded in the internal error log. Errors can be viewed in the error logs
by following the instructions in Section 2.3.2 under Menu 1 for Diagnostic Error Codes.
After power is applied the LCD screen on the front panel of the XR transmitter will light up. The display will look
different depending on the start up conditions:
•
If the XR transmitter has not recently been powered up, the time will start at 00:00:00 if in the 24 hour mode are
at 12:00:00 am if in 12 hour mode and there will be no parentheses to the right of the GPS tower symbol which
indicate that the transmitter is synchronized and the green LED will be off indicating that the transmitter is not
broadcasting.
•
If the XR transmitter was recently powered up, within the last 8 hours, the internal battery back up clock will set
the time immediately, and the LCD will come up with the correct time and date, there will be parentheses to the
right of the GPS tower symbol, and the green LED will be ON, indicating the transmitter is broadcasting.
•
If the XR transmitter is hooked up to a repeater, the GPS tower symbol will be replaced by an "R".
•
If the XR transmitter is loaded with a transmitter intermittent operation schedule and during this time period the
transmitter is scheduled to be disabled, then even if the transmitter is synchronized, the green LED will be
flashing, indicating that the transmitter power output is good but is not currently broadcasting.
