LCD screen shows 1 working frequency at a time and it will
change automatically each 5 seconds from low to high.
The repeater has a Manual Gain Control (MGC) feature that
allows engineers to reduce the gain of the repeater manually
via screen if oscillation is detected. Users could use the “Smart”
function as well, which will help to set to the suitable gain
automatically without any interference to the mobile network.
To maintain safe and specific output signal levels, this repeater
has a built-in signal oscillation detection circuit to adjust the gain
automatically to avoid interference to the cellular network, also
it gets color changing LED’s indicating its environmental status:
the Alarm LED’s located on the front of the unit changes color
from green to orange or red, (depending on the input power
level) when the system detects signal oscillation in the working
band or the input signal is beyond a safe limit. The repeater also
features a Network Safe / MUTE feature that automatically
shuts off the repeater to protect the cellular network. Users
shall make sure the LED remains green at all times for the best
system performance.
3.2. Alarm LED
Colour
Description
Green
The repeater works normally.
Red
The repeater works with medium oscillation. We recommend
checking the correct installation of the outdoor antenna (see Sec
4. Installation).
Attention!
It is crucial to adjust the gain or ensure sufficient shielding
between the antennas (see Sec 4. Installation). The Alarm LED will
turn green again otherwise normal operation of the repeater is not
possible.
Red
(Flickering)
The repeater can turn off at any time! There is a strong excess of the
total “signal level from the outdoor a repeater gain” over the
maximum output power of the repeater.
Attention!
It is crucial to adjust the gain or ensure sufficient shielding
between the antennas (see Sec 4. Installation). The Alarm LED will
turn green again otherwise normal operation of the repeater is not
possible.
