3. Pre-Installation Guidelines
a. INSTALLATION TOOLS
The following tools are required for installation:
•
Standard wrench and Phillips head screwdriver
•
Standard drill with ½” bit (optional)
•
Cellular device operating on 800 or 1900 MHz bands (any USA or Canadian
cellular device except Nextel)
•
Wire fasteners (optional)
•
Multi-meter for testing electrical continuity and AC and DC line voltage (for
troubleshooting only)
b. INSTALLATION PROCEDURE
Description of 4KMR-30U system
The 4KMR-30U 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 4KMR-30U 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 4KMR-30U dual band system operates with all carriers in the
USA and Canada except Nextel/iDEN providers.

The 4KMR-30U system contains a dual band low power indoor antenna, 40dB 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
