Notes about LCD Display
DL Output Power Amount: Indicates the
amount of DL output power for this frequency
band. 10dbm(4k) or 12dbm(10k) is the best .
DL Output Power Status: Indicates the
status of DL output power for this
frequency band.
Details: Click the corresponding
frequency band (the hot area
range is the entire instrument panel
+ text) to enter the frequency band
parameter details page;
Reset Screen: Click on the screen to
turn off the screen immediately,
and the touch screen lights up; if
there is no operation within 3
minutes, the screen turns off, and
the screen is turned on again to

Frequency band status: full gain status
(normal status, blue), weak oscillation status
(yellow), oscillation shutdown status (red),
and user active shutdown status (gray).
Band: Shows the working
frequency bands the
booster is operating on.
BLUE: Blue icon with ULN/AOL (Normal/Overload) indicates that a band is working correctly with maximum allowable gain.
YELLOW:
Yellow icon with OSC (Oscillation) indicates band gain reduction because of a slight self-oscillation condition. Due to
self-oscillation issue, please check the antenna system. Reinstall antennas and increase the isolation between outdoor and
indoor antennas, and then turn the booster on to reactivate the band and maximize performance. After the proper isolation is
done, the yellow icon will return to blue.
Note: when the icon is yellow, the band still works normally, but the gain is reduced.
RED :
Red icon with SHDN (Shutdown) indicates a band has been shut down because of a strong self-oscillation condition or
an over load condition (You could click the icon to see which condition now is). 1. For the strong self-oscillation condition,
please check distance and direction of outdoor antenna and indoor antenna, increase the isolation of both antennas. After
the isolation is enough, the red icon will return to blue upon reboot. 2. For the over load condition, It’s because of that the input
signal is too strong, please adjust outdoor antenna’s direction to reduce the strength of the input signal, then turn the booster
on to reactivate the band. When the gain is reduced enough, the red icon will return to blue upon reboot.
GRAY:
Gray icon with DIS (Disabled) indicates band has been disabled..
