Signal Booster Features
• Full smart to display all the parameters of the system. Automatic to detect the faults of the device and provide the corresponding solution.
• Automatic to shut down the power supply of the screen when no operation on it.
• Automatic detect the distance between receive antenna and relay antenna, avoid device auto excitation
• Automatic to adjust the system gain, The adjustment range up to 55db.
• High speed digital ALC system
• LCD screen display input/output real signal strength
• Automatic dormancy when no user make the calling, once detected the the user make the calling, the device will automatic switch to working status immediately.
• Uplink automatic shut off when device detected self-excitation.
• Uplink noise elimination. Did not interference base station absolutely.
• Small size, light weight, good looking, high gain, low power loss.
• Super intelligent display to guide the installation, Provide the easiest and simplest installation solution.
