Notes of WTEM-2T transmitter synchronized controller

When complete with this GPS synchronized controller, receiver should choose “GPS synchronization" and transmitter chooses “External synchronization".
To adjust transmitting frequency, first rotate the power switch (on the GPS synchronized controller) to “OFF" or have the transmitter stop transmitting directly, and then choose a transmitting frequency by rotating the frequency switch.
During working process, DO NOT cover the GPS antenna with any other object, otherwise, synchronization accuracy may decrease or GPS synchronized controller is unable to get into synchronization state. If satellite signal LED shows weak satellite signal received, adjust position of the GPS antenna to get wider range above it.
If working LED of the WTEM-1T/GPS transmitter synchronized controller shows that the controller gets ready to work, but the satellite signal LEDs flicker extremely, all lights are on or all lights are off, in this case, GPS satellite signal received is very weak and system has exited from synchronization state; until 16 seconds later, if system still fails to get again into synchronization state, the GPS synchronized controller stops to give transmitting control signal to the transmitter, and thus force the transmitter to stop transmitting power supply.
Under GPS synchronization mode, receiver could not automatically gain transmitting current and turn-off time; however, operator could read these two parameters on the process display on the transmitter.
