CDMA MINI repeater is used to fill out areas in CDMA mobile systems, such as base station
fringe areas, business and industrial buildings, etc.
CDMA MINI receives signals from a base station, amplifies and retransmits the signals to
mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both
directions are served simultaneously with the following features:
65MHz bandwidth service
Band Selection (5MHz , 10MHz , 15MHz , 20MHz , 5MHz+5MHz , 10MHz+5MHz,
15MHz+5MHz , 20MHz+5MHz , 5MHz+5MHz+5MHz) service
Roll Offs: 65 dBc at 1 MHz outside pass-band
The RSN-CDMA-30-C Repeaters are controlled by powerful microprocessors. Operational
status LEDs are visible on the bottom of the repeater.
The repeater works with convection cooling without fan because it has a radiator behind the

body of RSN-CDMA-30-C.
Operational parameters, such as gain, power levels, alarm condition, Automatic Gain Control
condition, etc. are set using a desktop or notebook and the Hyper Terminal, which communicate,
either locally or remotely via the UTP(Unshielded Twisted Pair Wire) cable, with the repeater.
Caution
RF EXPOSURE INFORMATION
Caution RF EXPOSURE INFORMATION a minimum separation distance of 7.9 inches
(20cm) must be maintained between the user and the external antenna of repeater to
satisfy FCC RF exposure requirements For more information about RF exposure, please

6. Troubleshooting
6.1 RF Connection check
<Problem>
Either the downlink output power or the uplink output power (=Input Power to the repeater)
is too weak.
<Solution>
Check if the following RF connections are loose:
1. The cable connection from the donor antenna to the donor antenna port
2. The cable connection from the service antenna port to the service antenna
6.2 Power Connection
<Problem>
All LED’s at the bottom are turned off.
<Solution>
Check if the power cord is connected correctly and the green LED at the bottom turns on.
6.3 Red Light on the Alarm LED
<Problem>
Red light LED turns on the Alarm LED after applying AC power.
<Solution>
Request a technical support.
