System debugging

a. Before switching on the power supply, please confirm the AC power input is standard

value again. Antenna cable and tri band repeater are well connected. Indoor antenna

keeps more 12 meters on horizon and vertical range with outdoor antenna.

b. Switch on the power to start the device, the red indicating light of power supply on the

panel lightening indicates the power has been connected and the repeater has begun

working.

c. Making outdoor antenna in position, now downlink indicating lights lighten or twinkle.

Otherwise, it can change outdoor antenna installation place or tilting angle of outdoor

antenna until downlink indicating lights lighten or twinkle.

d. Please install the indoor antenna in the central point of coverage area. And you go on

cellphone test at every corner of coverage area. According to the test results, please

optimize the mini repeater parameter installation place further and also the syestem

holding priority of up link signal indicating light lightens or twinkles. Right now, it means

that cell phone signal is well and it is able to communicate normally.

e. After finishing the installation, please make sure of spectrum analyzer or other measurement

devices to test relevant parameter whether it is met design requirements, especially to check

the VSWR, receiving and transmitting antenna isolation degree, downlink receiving

filed intensity etc. If the receiving filed strength is too weak,you can adjust the angle

and direction of the outdoor antenna. If receiving filed intensity is too strong, you can

consider adding fixed coaxial attenuator in BS communciation port or adjusting pitch

angle so as to lower the receiving electrical level. You also can do attenuation gain

adjustment to lower amplifying function from repeater.

Attention Items of Installation

a. Donor antenna should be installed away from the service antenna, at least 12m, and

the position where is 2m higher than the ground.

b. Service antenna is ceiling antenna which can be installed in ceiling and directed the

axis vertically to the ground. Please select the proper position to make the signals

distributed equally to every corner. If you choose directional flatpannel antenna install

in ceiling or wall, put antenna panel directly point to coverage area.

c. After all the RF cable has been installed, you should have an overall inspection to

prevent open-circuit and short-circuit. Because if the cable happens open-circuit or

shor-circuit. one part will not be able to work normally under slight damage conditions,

but it will destroy main device under worse conditions.
