troubleshooting only)
b. INSTALLATION PROCEDURE
Description of 4KSBR-50U system
The 4KSBR-50U Dual Band Wireless Amplifier/Repeater system provides cellular signal
coverage to interior areas that have low signal strength to adequately operate a cellular
phone. In these poor interior coverage areas it becomes difficult to place or receive calls
and usually results in a dropped call. The 4KSBR-50U dual band amplifier/repeater
system provides increased reception indoors by filtering, re-directing and amplifying the
available exterior signal. This translates into fewer dropped calls with clearer connections
and stronger signals. The 4KSBR-50U dual band system operates with all carriers in the
USA and Canada except Nextel/iDEN providers.

The 4KSBR-50U system contains a dual band low power indoor antenna, 60dB gain
amplifier/repeater unit and 9dB gain omni-directional outdoor antenna. Both antennas
must be installed and operate in a vertical position. The indoor antenna must be used with
cable and stand. The outdoor omni-directional antenna, PN 288-PW, is installed outside
