3 HOWTOINSTALLYOURNEWCELLULAR

BOOSTER(forvehicleinstallations)

3.1 Outsideantenna:

 Adopt the car magnetic antenna or chuch antenna.

 Function: receive the signal from the base station, through

the feeder to booster. Meanwhile transmit back the signal to

the base station after enlarge the signal.

3.2 Wirelesscarbooster:

Generally, hidden inside the corner nearby the power

supply

 Function: two-way, full-duplex amplifier the inside &outside

signal of the car, and the maximum uplink is to 2W.

3.3 Insideantenna:

 Adopt the car magnetic antenna or chuch antenna.

 Function: Transmit the enlarger signals to the mobile phone,

and receive the uplink car phone signal to booster.

3.4 Feeder

 When install, hide it in the decoration materials or pads.

 Function: Connect the feeder, antenna, and mobile phone

seat.

3.5 Powersupply

 Adopt the9V -12V power supply, and it is extremely

convenient for direct feed by the car power, also we support

the car charger.

3.6 Installnote:

When install, try to separate the inside &outside antenna to the max

straight distance, and make the inside and outside antenna could

not mutual see (also don't mutual see each other through the roof

skylight)

8 FREQUENTLYASKEDQUESTIONS

WHYARETHELEDLIGHTSTURNINGORANGE,REDOR

SHUTTINGOFF?



Therearecertaincaseswhereyoursystemcouldbeexperiencing

oscillation.Thiscanbeattributedtoeitherthequalityofyourinput

signalorhavingyouroutdoorantennaandindoorantennatooclose

together.Pleasereviewthefollowingguidelinestohelpresolvethis

issue:

1. Adjustthedirectionoftheoutdoorantenna.Ifthesystemis

receivingaveryhighinputsignal,youcanpointyouroutdoor

antennaawayfromthecellulartowertoreducethestrengthofthe

inputsignalandtherefore,reducetheoscillation.Alternativelyif

yoursystemisreceivingaverypoorqualitysignal(weakand

unusablesignal),youcanpointyouroutdoorantennamoredirectly

towardsthecellulartowertoincreasethestrengthoftheinputsignal.

Sometimesthismayrequirecompletelyrepositioningtheantennato

alocationwhereyoucanachievealineofsitetothetower.

2. Increasetheseparationbetweentheoutdoorantennaandthe

indoorantenna.Thiscanbeachievedbyincreasingthedistance

betweenthetwoantennasorbyplacingbarriersbetweenthem,

suchasmovingtheindoorantennatoanadjacentroomwherethere

wouldbeanadditionalwallseparatingthemfromtheoutdoor

antenna.
