Handling the SelectaCell®
1. Use ESD precautions when dealing with the modules within the SelectaCell™ so that units are not
damaged.
2. Opening the unit voids warranty.
3. Disconnecting any component within the SelectaCell™ when powered can damage or destroy the
equipment and will void the warranty.
1.0 Description
The SelectaCell® repeater, is a PCS band, band selective bi-directional amplifier with integrated donor
and server antennas. The unit is designed to provide enhanced RF coverage for wireless systems in
small facilities. Usage includes providing coverage in retail stores, offices, warehouses, restaurants,
homes, etc.
The SelectaCell®
supports all 1900 MHz system protocols including CDMA, GSM/PCS1900 and
TDMA and a single model will cover PCS licensed 5MHz or 15MHz bands/sub-bands A through F.
The SelectaCell®
features easy set-up, lightweight, compact enclosure with internal antennas, local
alarming, excellent electrical specifications, high reliability and cost effective pricing.
2.0 Functionality
The SelectaCell® is capable of automatically adjusting its own signal gain levels up to the maximum
output power levels. SelectaCell® detects the downlink output power and adjusts the level for +12
dBm EIRP composite output power and continues to monitor and reset the gain as required for proper
system performance. For example, when CDMA protocol is being amplified, there could be an error
in set up initially resulting from only pilot sync, and paging Walsh codes being present on the RF
carrier. The SelectaCell® will reduce the system gain until no signal is received that will exceed the
output power setting. This prevents the SelectaCell® from setting up to a higher power level than
actually desired if all of the Walsh codes were present. The gain does not continually change to
maintain an output power of 0 dBm (AGC) since this would defeat the benefits of power control in the
service providers system.
3.0 Alarming
Alarming monitoring is accomplished in the SelectaCell® by the microprocessor, which will detect a
failure in gain or a system oscillation. This is indicated to the user by the LCD display and by
application software via the USB interface.

SelectaCellTM Operator’s Manual – Preliminary EMS Wireless
4.0 Primary Power
The SelectaCell® operates on 7.5 VDC input power @ 0.7 Amp. This unit is supplied with a regulated
wall mount power supply, which is UL, and CSA listed and will operate on AC input voltage of 90-240
VAC.
5.0 Donor/Server Antenna
Internal donor and server antennas have 13 dB and 10dB gain, respectively. The donor antenna must
be orientated to point in the direction of the Service Providers cell site location, but does not necessarily
have to point exactly at the cell site. The indicators will provide a reference of the strongest RF power
strength when the antenna is located in the optimum location.
6.0 Installation:
Note 1: The user is cautioned that modification or changes to this device not expressly approved by the
party responsible for compliance could void the user’s authority to operate this equipment.
Note 2: Manufacturer’s rated composite output power, individual channel power will vary depending on
the number of channels and distance from each cell site being received
Note 3: This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that
this device does not cause harmful interference.

7.0 Introduction
SelectaCell® setup is automated for easy installation. This section will provide the basic steps to
performing the unit’s setup and installation.
SelectaCell® is designed to automatically optimize set up and will improve performance in most
applications as long as a signal can be received at a window. Actual area of coverage that will be
improved will vary depending on the signal level received and blockage.
Placement of the unit
The SelectaCell® unit should be located in a window where the user’s service provider has enough
coverage to initiate a call. For best results, the user should select the window with the greatest signal
strength. This can be determined by observing the number of bars on the user’s cell phone:

8.0 Setup Instructions
There are two setup methods that may be used to select and set a 5 or 15 MHz frequency band on
SelectaCell™;
a. Manual Push Button
b. Computer setup through the USB ports
Setup Instructions using the Manual Push Button
SelectaCell-19S must be set up to the proper assigned frequency band before completing installation.
After band selection, the unit will enter the downlink monitor state for determining optimum
positioning of the unit. Once this process is complete, the unit will power up in the assigned band
(displayed in preamble) each time the unit is power cycled.
LCD Preamble Message:

Band A Assigned band
Test for signal strength at each window to identify the location with the greatest signal strength.
1. Using a subscriber unit (cell phone) and monitoring the signal strength indicators (number
of bars displayed on the phone), check each window location. The window location that
has the most displayed bars should be the location selected. Place the unit on the
windowsill or on a counter or nearby table top or other convenient location with the LCD
display facing indoors.
Note: Please do not locate the SelectaCell in an area that can be obstructed either in front or behind,
e.g. bookshelf, cornered areas, behind closed blinds or plants
.
A. Select PCS Band of Operation Manually
Select by:
1. Depress and hold button (which is located just above the USB port) about 3 seconds while
connecting AC power to the unit.
2. Release button during the preamble messages being displayed on the LCD screen.
3. Current band assignment setup on the unit will display, blinking on/off (e.g. Band A)
4. Each time button is pressed, it will now advance the unit to the next band in 5 MHz
segments. Continue pressing the button until the desired band either 15 MHz or 5 MHz
band segment is selected. If desired band is already displayed, proceed to next step.

5. Once the desired band is selected, hold down the button for 3 seconds, this will now
program the unit for the selected band and enter the unit into downlink monitor mode.
6. In downlink monitor mode only the downlink signal is being amplified. The LCD display
will have bars on the left side indicating downlink signal and bars on the right side
indicating downlink gain.
7. Position the unit to achieve maximum signal strength by rotating the unit slightly while observing
the bars for maximum signal strength.
