Important Safety Information

Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. The outdoor antenna used
for the purpose of communicating to the wireless infrastructure is limited to 14dBi gain, or any combination of gain and loss that
equates to 14dB at input. Each antenna must be positioned to observe minimum separation requirements from all users and
bystanders. The following guidelines should be used when considering separation distances.

INDOOR antennas must be placed such that, under normal conditions, personnel cannot come within 20 cm (~0.65 ft.)
from any inside antenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF
exposures beyond the maximum permissible limit as defi ned by section 1.1310 i.e. limits for General Population/Uncontrolled
Exposure.

OUTDOOR antenna must be positioned such that, under normal conditions, personnel cannot approach closer than 122 cm.
(~4 ft.). A directional antenna having a maximum gain of 14 dBi is used, precautions should be taken to prevent personnel from
routinely passing through the main radiation beam at a distance closer than specifi ed.

Product Introduction

Cellular Specialties, Inc. (CSI) developed the CS17-145-410 LTE - 700 U7C repeater for use within enclosed structures where
signal strength from the local cell site is insuffi cient to operate mobile phones. Adequate signal must be available outside the
structure as a prerequisite to achieving in-building coverage. The Repeater is connected via coax cable to an external antenna,
usually on the roof, and to one or more internal antennas placed strategically throughout the area where wireless service is
desired.

The external antenna typically is directional, such as a “yagi”. Internal antennas are typically omnidirectional, although various
other types may be used depending on the coverage application. The Repeater amplifi es both the “uplink” (phone to tower) &
“downlink” (tower to phone) signals thus facilitating communications to and from the intended wireless infrastructure.

With a maximum total of +85dB nominal gain on both the up and down links, gain can be adjusted over a range 30dB in 1.0dB
steps. Control of the repeater is achieved utilizing a computer connected to the NMS 9 pin D-Sub RS323C port. This model is
designed to cover the Upper C portion of the LTE 700 MHz band.

Important Installation Notes

• Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. This feedback can
cause the amplifi er to emit a continuous signal at maximum amplitude and, in some cases, interfere with normal operation of the donor
site. Careful consideration of the layout and placement of the system is imperative to minimize this possibility and to minimize the amount
of signal leaking from the building. See installation tips for general guidelines.

• The installer should refer to the Safety Guidelines section and the Important Safety Information section for proper antenna selection
and installation. To avoid serious injury or death and damage to the repeater, do not install donor or server antennas near overhead power
lines or high power components. Allow enough distance so that if antennas should fall they will not come in contact with those compo­nents.

• Close proximity to the donor or server antennas with the repeater in operation may expose the user or installer to RF fi elds that
exceed FCC limits for human exposure.

WARNING! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE REPEATER

OR THE COAX THAT LEADS TO THE REPEATER.

Installation Tips

Donor Antenna

1. Accurately determine the azimuth to the donor site . Obtain the donor site information and approval from the

service provider/carrier.

2. Ensure that the radiation path to the donor site is as unobstructed as possible.

3. Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site. Try to avoid having the RF
signal from the donor pass above the location(s) of the service antennas. Normally the service antennas will be behind
and below the donor antenna if viewed from above. This approach will help avoid interference and feed back both, to and
from the service antennas.

4. Normally mounting the donor antenna higher will allow a less obstructed path to the donor site. However, in high traffi c
metro areas avoid mounting the donor antenna any higher than necessary as the quality of the donor signal may start to
become less stable and it is more likely to encounter adjacent channel interference.

5. When possible shield the donor antenna’s back side by locating it so that any HVAC units and/or penthouse structures are
behind the antenna relative to the donor cell site location.

Indoor Antennas

1. Use omnidirectional antennas (see optional accessories) indoors, and locate them centrally with respect to the intended
coverage area to minimize signal leakage to the outside. Use directional antennas indoors only in special cases when higher
gain and directionality would be helpful and RF exposure limits will not be exceeded.

2. To avoid repeater uplink overload and gain limiting mount the indoor antennas away from areas where mobile subscribers
frequently use their phones such as desks or dispatch areas.

3. To determine the quantity and locations of indoor antennas, use an appropriate phone’s signal meter to determine areas of
weak signals. These are the approximate areas where indoor antennas may be needed. Also be aware the signal from an
indoor antenna, in most cases, can be expected to penetrate about two standard offi ce sheetrock type walls to reach users.
After two walls or if the walls are made of other materials, it may be necessary to split the available signal and add more
antennas.

Mounting the Repeater

The following photo illustrates the innovative mounting bracket design that makes wall mounting the repeater
fast and easy.

1. Using the detachable bracket as a
template, mark the locations for the
wall anchoring system.

2. Drill holes, install wall anchors
and lock the wall mount bracket in
place.

3. Slid repeater into receiver rails of
the wall mount bracket.

Note: The wall anchoring system
selected will depend on the material
used in the wall where the repeater
is to be mounted. It will need to be
capable of supporting the weight of
the repeater (12.2 lbs / 5.5 kg) and
all the cabling attached to it.

Physical System Set-Up Verifi cation

All cables should be checked for shorts and opens. Also verify that there are no cables with loose or poor connections. RF leakage could
cause oscillation to occur under some conditions.

The rooftop antenna (Donor Antenna), if directional, should be checked for proper alignment along the calculated compass heading.
Typically, the directional antenna would be aimed at the same site that your handset uses, but it may not always be so. It is critical the

installer contact the service provider for information on, and approval of, the site he or she has selected before
the system is turned on.

If cables and alignment are acceptable and a problem persists, it may be necessary to use a spectrum analyzer to examine the signal
environment in which the unit is operating. The existence of strong adjacent channel signals within the frequency band(s) can cause the
AGC to reduce the amplifi er’s gain or cause alarms. In some cases additional fi ltering or attenuation might be required to reject these
unwanted signals. In some instances, the donor antenna can be reoriented horizontally, to place the interference source in an antenna
pattern “null”. There also may be some cases where the interference from outside signals is so great that they cannot be fi ltered or oth­erwise reduced or eliminated without expensive and possibly prohibitive measures. In these cases it may not be practical to use the CSI
repeater for providing coverage to these sites.

Controlling the Repeater

Control and monitoring of the repeater requires that a properly confi gured computer, with CSI’s LTE700 control software
installed, be connected via a serial cable (optional), as shown in fi gure 1, from the serial connector of the computer to the serial port

labeled NMS on the bottom end panel of the repeater. If the gender of the connector is not the same as shown in fi gure 1, a null modem
adapter (optional) as shown in fi gure 2 may also be required. If your computer does not have a serial connector, a USB to Serial Adapter
may be a option for you.

Figure 1

Note: It may be necessary, in the System Properties section of the control panel; using Device
Manager to determine what COM port your computer uses for the communications port. In many cases it’s COM 1.
