The indications of the status LEDs are:
CONSTANT GREEN:
The transmitter is working correctly, no further adjustment is required.
CONSTANT RED/GREEN:
The transmitter is working at its maximum output and the gain should be reduced slightly until a
constant green is achieved.
CONSTANT RED:
The Transmitter has detected an error or interfering signal. One reason may be that the external
antenna is picking up the signal from the transmitter and a feedback oscillation is occurring; it is
strongly advised not to locate the external antenna and repeater too close together.
It may be that the power is set too high; decrease the gain on the repeater slightly.
Another common reason is that there is an interference source close to the receiving antenna.
Locating the antenna, repeater and associated cables as far away from existing wiring, machinery and
pipework will normally avoid this situation.
Troubleshooting guide:
Problem:
No LED indication
Solution:
Check power supply and connection.
Problem:
Red light is on.
Solution:
The gain setting is too high. Turn the control knob counterclockwise to decrease the gain
until the green LED is lit.
Problem:
Green light flashing around 5 times per second, red light is off.
Solution:
Transmitted signal level is too low. Turn the control knob clockwise to increase the gain. In
normal operation, only the green LED is continually on. In all other cases please check the
antenna connections at both ends before making any gain adjustments.
