Switch moving up as 1 makes gain attenuation, while switch moving down as 0 makes gain remain original. Factory default
setting: all switch down. For example, when switch 1 and switch 4move up, the corresponding truth table attenuates 9dB.
When BS connection port receives GSM/ DCS/3G signal which surpasses-50dBm, indicating light lightens or twinkles. Now
the device receives well and it's able to communicate normally.
When BS connection port receives GSM/ DCS/3G signal with surpasses -60dBm, indicating light shows in Green. Now the
device receives well and it's able to communicate normally. When system internal self-excitation, the indicating light from
Green to Orange, to overcome the self-excitation please reference to common problems.
Attention: Just one band is occupied when cell phone is working, therefore, in general usage of tri band repeater, only
downlink and occupied band for uplink indicating light illuminate.
