The device is a RF wide band repeater, making the following situations requiring attention:
?
Where there are more than 2 mobile operators, working in the same frequency band of the repeater, and
a BTS is located a few hundred feet from the installation site and the other mobile operator has the BTS
a little further, then the dominating signal will be amplified with priority.
?
ALC ( Auto Level Control ) in this case works to 35 dB. The stronger signal will be amplified rather
then the lower one.
?
Attach the cable on the wall,window etc and the holes to be consistent with the cable diameter
?
The outdoor cable connects on the repeater at the OUTDOOR port, and the indoor cable connects the
repeater at the INDOOR port
Testing and commissioning
Test the mobile phone signal everywhere in the room, when the signal on the phone indicates 3 or 4 bars at the
corner of the room, in the diametrically opposite place from the indoor antenna, it means you have the best
indoor reception. If you don't, resume the installation of the external antenna, it might not be receiving the best
outdoor signal, or check if there is enough RF separation between indoor and outdoor antenna. For not causing
self- oscillation, the repeater will decrease automaticaly it's gain and this will result in a smaller coverage area.
If you notice that during the phone call, the caller will not hear you well, or with interruptions, and you have a
good reception, then you need to reposition the external antenna with very fine movements from left to right or
vice versa.After repositioning wati 10 seconds to initialize and try to call again.Repeat this procedure until you
have a good reception and transmission rate, without interruption.
Uplink LED will start flashing on ad off during a call in normal operating conditions.
Questions and Answers
Self-oscillation
Improper installation of antennas, change their place as soon as possible !
You know you're system is self-oscillating when:
To avoid please increase the distance between external antenna and indoor antenna and be sure the
amplified signal is not emitting into the outdoor antenna !
?
Have a maximum signal level on the phone but when making a call, the
call is not initialized – call dropped or error in connection
?
Both Uplink and Downlink LEDs are flashing ON-OFF
?
The signal drops to null suddenly when repeater is ON
