Страница: 14 / 21

When the device completes the internal self test, it shows the standby screen. If the arrow down is displayed at the
bottom right corner, the device has detected signal reception problems. In this case press Page Down button to see
possible solutions. Resolve 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 thelargest possible distance from the indoor antenna.
LINE 2. MS shows the output power of a booster.
Note! The MS (output power) index must be b05 and +15 dBm. Device Gain must be 65/65 dB.
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.
UP Button : Go to the previous page to check the functioning status of the device or see the error description.
