Safety Precautions
Opening the CDMA equipment could result in electric shock and may cause severe injury.
Connect the equipment frame ground to building ground.
Operating the CDMA with antennas in very close proximity facing each other could lead to severe
damage to the repeater.
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 visit the FCC website at www.fcc.gov
This equipment is for indoor use only and enables the communication wiring to communicate
only inside the building.

ALC (Automatic Level Control)
ALC feature prevents the repeater from exceeding its maximum output power by reducing the gain
automatically. ALC is used to adjust the gain to an appropriate level for a range of input signal levels.
ASD (Automatic Shutdown)
Automatic shut down protects the repeater from the oscillation or excessive input signal and
eliminates any degradation to the network.
There are three parameters: ASD Level, ASD Time, and ASD Iteration.
If the output power gets higher than “ASD LEVEL”, the repeater will shut down for “ASD TIME”
seconds and then it will turn the amp back on to measure the output power again. If this repeats at
“Iteration” times, the repeater will shut down completely.

1. Introduction
CDMA MINI is used to fill out areas in CDMA mobile systems, such as base station fringe areas,
business and industrial building, 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:
Donor
antenna
Server
antenna
Base
Station
CDMA’s Key Features
♦ Programmable Bandwidth and Band
» 5, 10, and 15 MHz contiguous and non-contiguous segments
» Any Band Combination within 65MHz PCS Band [A,D,B,E,F,C,G]
» Two (2) 5MHz segments
♦ Easy and Quick Installation
» Web-based GUI
» Plug and Play - DHCP Server @ Local Port
» Automatic Easy Setup (Recommended)
» Isolation Detection
♦ Auto Level Control & Auto Shut Down
- CDMA MINI utilizes the web-based user interface and web server. There is one physical RJ-45
port:
• The Local port provides the on-site access to the repeater.
- DHCP server at the Local port enables Plug and Play by automatically assigning the IP address
to the user’s computer.
• Easy Setup has the following features.
-It will measure the isolation and limit the maximum gain accordingly. This will also enable Auto
Level Control as well as Auto Shut Down. These two features are strongly recommended to
prevent the uncontrolled power output, which could have an adverse impact on the RF network
and the repeater. For example, ALC will automatically apply attenuation when the input signal
strength is increased due to the new base station deployment near the repeater site.

3.2 Mounting
CDMA MINI is easy to mount using the assembled mounting bracket, which has 4 holes for the
provided 5/16” fixing screws.
Step 1 : Drill holes directly through the template.
Step 2 : Install the set anchor bolts or the plastic anchor bolts on the holes.
Step 3 : Attach the mounting bracket to the wall using provided bolts or extra screws.
15
Step 4 : Lean the CDMA to hang the topside of the Guide Ring on the mounting bracket,
and push toward the wall to mount.
Step 5 : Fix the CDMA MINI using 8 screws.

3.3 Grounding
A rod on the left side is intended for a building ground. Connect the ground cable to the rod.
17
3.4 RF Cable Connection
Step 1 : Connect a cable from a donor antenna to the Donor Antenna Port.
Step 2 : Connect a cable from a repeater’s service antenna to the Server Antenna Port.
Model Max Gain Minimum required isolation
(@Max Gain)
CDMA MINI 50dB to 80dB ≥95dB(80dB+15dB)
3.5 Power On
Step 1 : Connect the power cord.
Step 2 : Plug the power cord into a wall outlet.
Step 3 : Check if the green LED at the Top turns on.

This repeater follows the below set-up algorithm automatically right after POWER ON
< Auto easy-setup Procedure>
The below algorithm shows how to control Gain, Input / Output Power Level, Service
band, ALC Level, ASD Level and path direction by using keypad display panel.

5. Troubleshooting
Before contacting your service dealer, please make sure you refer to the following guide. If the
CDMA MINI does not work normally after completing the following troubleshooting, please
contact your local dealer or service center.
Problem Cause Solution
No LED on Check the power cord for secure
connection.
Cannot communicate
with the repeater.
Redo the ‘4.2, Network Setup’ of this
manual. If communication still does not
work, please contact Technical Support.

The mobile phone is
not working well.
Check if the power is ON
Check if the DL Amplifier and the UL
Amplifier of Parameter Status are
displayed as ”ON”.
1. Gain, Input/ Output
power or DC current
are changed
randomly under
operating of DL ALC,
UL ALC, and ASD.
2. Over isolation
attenuation range.
Oscillation a. Turn off the repeater
b. Measure the isolation and verify if the
isolation between the donor antenna and
the service antenna is enough for the
repeater. Refer to the note on page 19
If the measured isolation value is greater
than the required isolation value, turn
Power ON.
The red light
turns on.
Check if DL Input Power, DL Output Power,
UL Output Power, Temperature, DC
Voltage, DC Current is out of range.
Especially, if the Input Power or Output
Power is out of range, please contact
Technical Support.
