the issue basing on the recommendations.(see possible troubles and solutions below in Questions & Solutions paragraph)
If the problem is resolved, the screen will display as below. No arrow means that the repeater works correctly:
LINE 1. BS shows the level of outdoor incoming signal for the corresponding frequency band. Make sure it is as low as possible.
Note! For the optimal functioning of the booster, the BS (input) index should be from -65 to -50 dBm. If the BS is lower than -
65dBm, the coverage will be smaller. However, the device can work normally. If the BS is too weak, it'll be necessary to adjust the
position of the outdoor antenna by raising it as high as possible (on a pole on the rooftop) and pointing it towards the provider's
nearest base station.
If the BS is higher than - 50 dBm, the device will have self-excitation issue. In such cases, the output signal will drop during
communication. If the antennas are placed very close to each other, it will evoke self-excitation. To fix the problem, you would
need to place the outdoor antenna at the largest possible distance from the indoor antenna.
LINE 2. MS shows the output power of a booster.
Note! The MS (output power) index must be b01 and +15 dBm.
LINE 3. Device gain shows the current gain (left) and maximal gain (right) of the device. For optimal function both values must be
equal (current gain=max gain).
Line 4 shows that power supply is connected and works properly (DC5V) and automatic gain control of the system is also active
(AGC).
LINE 4. Power DC 5V shows that power supply is connected and works properly. AGC function for automatic gain adjustment.
Note! In LINE 4 in its right corner can appear the exclamation point or an arrow . It denotes an installation error. Use UP and
DOWN buttons to see the reasons. For more details, read the section QUESTIONS & SOLUTIONS.
