Overview
The WRE2710 Wireless Network Range Extender is a high performance, microprocessor controlled,
bidirectional RF amplifier for the entire North American 850 MHz cellular and 1900 MHz PCS frequency
bands. The amplifier has an automatic gain and oscillation control system that will automatically adjust
the gain and the output power if a signal anomaly occurs. This amplifier is designed to operate as a
direct connect unit within a cellularsystem, for maximum performance in weak signal coverage areas.
The input power requirements for the amplifier are positive 8.0 to 32.0 volts DC (negative ground).

Installation with an SMA Device- Mobile Location
1. If connecting to a Cellular Modem or Mobile Data Terminal (e.g. Raven X, etc) in a vehicle or
mobile application, connect the SMA to SMA device cable (#5on Parts List) to the ClearRF
Amplifier connector marked “Device”.
2. Connect the SMA end of the SMA-to-SMA device cable to the CellularModem or MDT antenna
connection.
3. Mount the OutdoorSignal Antenna (#4on Parts List) vertically on any metal surface on the roof,
hood or trunk of the vehicle.

MAN-5446-001 Rev 7 8
4. Connect the Outdoor Signal Antenna connector to the ClearRF amplifier SMA connector marked
“Antenna”.
5. Plug the 12V Hardwire DC Cable (#3 on Parts List) into the vehicle fuse block. You must connect
the red wire to a positive terminal from the fuse panel with a3 ampere fuse rating. The black
wire should be attached to a ground of the vehicle. Power may also be provided to the amplifier
using a 12V cigarette lighter adaptor. (not included, available at www.clearrf.com)
6. Insert the Hard Wire DC Cable connector plug into the amplifier and watch the LED indicators.
LED Diagnostics
Once the amplifier is installed properly and power is applied, the LEDs will both turn on followed by
the green LED flashing. The green LEDwill flash while the amplifier increases its gain to the optimum
level. The red LED may also flash during this stage while the gain (power) is properly set on the
amplifier. When power control is established, the green LEDwill remain constantly on. You may see
the green and red LEDs flash back and forth, THIS IS NORMAL. In areas where the cellular network is
adequate, the amplifier will maintain a maximum power level acceptable for normal operati on and
prevent overloading the wireless phone, as well as keeping RF signal levels at aminimum for a
healthy environment. If the red LED is constantly on and the green LED is off, the amplifier has
detected a fault. The amplifier will shut down automatically and restart. If the fault persists,
reposition the antenna until normal operation is achieved. - Once normal operation is established,
you may permanently mount the antennas in the locations you chose in the prior steps.

MAN-5446-001 Rev 7 9
Diagnostic LED definitions
1. Solid Green and Red –LED test, the unit is initializing
2. Solid Green –Normal operation
3. Flashing Green –Normal operation, increasing gain setting
4. Solid Green and Flashing Red –Normal operation, decreasing gain setting
5. Solid Red and no Green –Fault detected (Unit will shut down until power is cycled.)

parts and additional accessories may also be available.
Passive Bypass Technology –Patent Pending
The WRE2710 amplifier is equipped with ClearRF’s Passive Bypass technology. This feature allows the
amplifierto passively bypass itself and become merely a pass through cable when amplification is not
necessary, during loss of power or when a fault is detected.
Passive Bypass technology is useful in applications wherethe amplifieris mobile, moving in and out of
poor signal areas. The amplifierwillbypass itself when close to cell towers, completely eliminating any
potential for network disrupting noise power caused by too much amplification near a cell tower. The
technology is also extremely useful in fire and security system installations where a connection with the
antenna must always be maintained, even with loss of power.

FCC ID: XS7-WRE2710
IC ID: 8918A-WRE2710
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1 ) this
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
The term “IC:” before the radio certification number only signifies that Industry of Canada technical
specifications were met. The Manufacturer's rated output power of this equipment is for single carrier
operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5
dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This
power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of
the device.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec
porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la valeur nominale de 3,5 dB,
surtout si le signal de sortie est retransmis et qu'il peut causer du brouillage aux utilisateurs de bandes
adjacentes. Une telle réduction doit porter sur la puissance d'entrée ou sur le gain, et ne doit pas se faire au
moyen d'un atténuateur raccordé à la sortie du dispositif.
FCC Regulatory Guidance: ClearRF’s WRE2710-S operates under the rules and regulations as provided by the
Federal Communications Commission (FCC). For more information on these rules and regulations, please
contact the FCC directly at (888)-225-5322.
