Read First Before Setting Up Your zBoost®
Before unpacking the contents, verify that your mobile phone operates on the frequency band supported by
this product.
• zBoost® YX520i will enhance your in-building coverage for local provider networks operating at
900MHz and 1800MHz frequencies.
Caution: Before beginning installation, you must have enough space
to provide 5 meters of vertical separation between the Signal Aerial and
Base Unit. Less than 5 meters will result in reduced performance.
To verify that your mobile phone will work in conjunction with the model purchased, please follow
these four simple steps:
Unpack the Base Unit, Base Unit Aerial and power supply.
1. Connect the Base Unit Arial to the Base Unit. Choose the
correct power adaptor for your geographical location and
attach to the power supply. Connect the power supply
to the Base Unit and plug into an outlet. e signal light
should be solid green.
2. Now bring the unit (Base Unit, Power Supply and Base
Unit Arial) to an area where there is enough signal to
place a call (using an extension cord may be necessary).
Ifthe Signal light stays green while placing a call, you may
proceed to the next step: Setting up your zBoost® Signal
Booster. If it ashes red, move your mobile phone further
away from the Base Unit and retry, it may be necessary to
disconnect the power for 10 seconds and then reconnect
the power.
3. If the Signal light does not stay a solid green, try placing
another call with your mobile phone next to the Base
Unit Aerial. If the Signal light still does stay green, your
mobile phone may be operating on a frequency that is not
supported by this zBoost model. Some carriers, change
frequency depending on location. Email Wi-Ex technical
support at [email protected], or call 001.800.871.1612
for further assistance in identifying your frequency.

Preparing to Set Up Your zBoost® Product
Overview
ank you for choosing zBoost®. You will now be able to use your cell phone INSIDE your home or oce.
Gone are the days when you had to go to the window upstairs or walk outside to use your cell phone. Like
a skylight that brings sunlight into your home, zBoost® transports and amplies the outdoor cellular signals
into your home or oce.
By following the easy instructions in this user guide, you will be Extending Cell Zones™ into your home or
oce.
Why Indoor Signals Can Be Weak
ere are several obstacles that can contribute to the poor reception you receive in your home or oce:
1. Location of the Cell Phone Tower in Relation to Your Home/Oce
While cell phone providers have tried to place cell phone towers to provide the best overall coverage,
local ordinances and terrain features can impose restrictions on where these towers can be placed,
thus, limiting the signal strength available at your location.
2. Obstructions Caused by Buildings, Terrain and Trees
Cell phone signals can be completely blocked or reected by buildings, walls, trees, hills and other
terrain features resulting in low signal strength.
3. Energy Ecient Windows
ese new windows can also aect signal penetration into the house
Tools Needed
e following tools are needed to set up zBoost®:
• #2 Philips screwdriver
• Cellular phone operating in the band supported by your zBoost® unit
• Drill (may be required for outdoor or attic antenna placement)
Cell phone signal bars are approximate and vary from
phone to phone. e number of bars can uctuate widely,
depending on the location of the phone, the position or
angle of the phone, weather, etc. Most cell phone signal
meters update every 6 to 10 seconds. An increase of only
one bar typically indicates a 4x to 10x signal increase.
Check for Signal Strength
Before placing a zBoost® in your home, make sure that you can place calls on the outside of your home, in
the attic, at roof level or wherever you plan to place the signal antenna. zBoost® can only bring signal into
your home when signal reaches the Signal Antenna. If there is no signal, the zBoost® will not work for you.
Using your cell phone, place a call from an outdoor location to conrm that enough signal is present to
complete the call. If a weak signal is available at ground level, check the signal strength in your attic or at
roof level location where the signal will likely be stronger and where the Signal Antenna can be placed for
best performance.
If you can reliably make and receive calls outside your home, then zBoost® can bring the signal into your
home.
If only one signal bar is displayed on your cell phone outside, indoor coverage will be limited to one
small room. We recommend placing the Signal Antenna outside and/or purchasing a Wi-Ex® upgrade Signal
Antenna for increased coverage (see page iv).

Determine Coverage Area Needed
Identify the location in your home/oce where you need signal coverage the most. e zBoost® YX520i can
cover approximately 250 square meters (coverage varies based on outdoor signal level, building construction,
and placement of aerials). Walls, ceilings or oors will reduce the coverage area.
Determine the Location of Signal Aerial and Base Unit Aerial
It is recommended that the Signal Aerial and Base Unit Aerial have approximately
5 meters of vertical separation.
If the aerials are too close together, the signal light on the Base Unit will ash red indicating a problem (See
Page 12, Troubleshooting). To capture the best signal, place the Signal Aerial as high as possible and position
it vertically, keeping it at it at least 1 meter away from any metal.
e location of the Signal Aerial should be at least 5 meters higher than the Base Unit Aerial. If this is not
possible, maximizing the horizontal separation between the two aerials is advised. See page 6, Setting Up
Your zBoost® Product, for additional information.
Additional Cable Requirements
If the distance between the Signal Antenna and the Base Unit exceeds 50 feet, extension cables are available
on our website or at many home improvement and electronic stores. e included cable is RG59-mini. For
better performance, you may replace it with RG-6 cable for satellite TV.
e total cable length should not exceed 70 feet unless you also purchase an upgraded signal antenna (see
page iv). A longer cable is helpful only if it allows you to place the Signal Antenna in a location where you
measure stronger signal.
Grounding the Signal Antenna
If you decide to place the Signal Antenna outdoors, it must be properly grounded. (See page iv for a
recommented grounding kit).
e set up must be in accordance with Article 810 of the National Electric Code (NEC). A listed antenna
discharge unit must be provided for the lead-in coaxial cable per NEC article 8.10.20 or the shield of the
coaxial cable must be permanently and eectively grounded in accordance with NEC article 8.10.21. Please
consult a professional installer or electrician for more information. (See page iv).
Securing Cable with a Drip Loop
If you place the Signal Antenna outdoors, create a drip loop with the
coaxial cable at the point where the cable enters the building through an
outside wall. is can be done by twisting and securing the cable into a
loop (no less than 4” across) near the entry point. is will help prevent
moisture from gathering at entry point and leaking into the building.
Consult a professional installer if you need more information.
Power Requirements
e Base Unit can be plugged into a standard 2 or 3 prong 110 VAC receptacle using the Included power
supply. e power supply consumes less than 10W (less than 0.2A).
e zBoost® YX520-I base unit MUST only be used with
the provided power adaptor. Use of other power adaptors
will void the warranty and may damage the unit. Use of
other equipment is not FCC approved.
Coax Cable
Exterior Wall
Note
Avoid placing the Signal Antenna near metal such as
wiring, A/C ducts, metal siding, truss plates, etc.
When connecting the cable to the antenna, run the cable
straight down from the antenna. Avoid draping the coax
near the antenna.

Setting Up Your zBoost® Signal Booster
Placement of the Signal Aerial
Choose a location for the Signal Aerial that provides the best performance and the largest area of improved
signal. Determine the location that provides the strongest signal using the signal strength indicator on your
mobile phone. Find the location that provides the most bars of signal strength and place the Signal Aerial
at or near that location. Avoid placing the Signal Aerial near metal such as wiring, A/C ducts, metal siding,
truss plates, etc. When connecting the cable to the aerial, run the cable straight down from the aerial. Avoid
draping the coax near the aerial.
Choose 1 of the following 3 options for setting up your zBoost®
system:
EASIEST: Inside, by a window
Locate a window where you get service.
1. Mount the Signal Antenna above the window. e
coverage your zBoost® provides is largely determined
by the quality of signal received by the Signal Antenna.
2. Assemble the Base Unit Antenna. Place the Base
Unit in desired location – where you want to create
a Cell Zone™ (15 feet of vertical separation between
the Base Unit and Signal Antenna is recommended).
Connect the Base Unit Antenna to the Base Unit and place it
where you need signal.
3. Attach the coaxial cable to the Signal Antenna.
4. Connect the other end of the coaxial cable to the Base Unit.
5. Attach the Base Unit Antenna to the Base Unit and position it vertically.
6. Connect the Power Supply to the Base Unit and plug into a power outlet.
NOTE: If a red light appears, try further separating the Signal Aerial and Base Unit or see the
Troubleshooting section (Page 12) for further information.
Upon initial power up, a solid GREEN light should appear indicating normal conditions. If a RED light
appears, adjustments may be needed to optimize performance. If you nd the increased signal coverage is
acceptable, however, no additional adjustments are needed. See Light Indicator section (Page 12) for more
BETTER PERFORMANCE: Outside of a window
Locate a window where you get signal.
1. Locate a window where you get signal.
2. Mount the Signal Aerial outside of the window.
3. Place the Base Unit in desired location – where you
want to create a Cell Zone™ (5 meters of vertical
separation between the Base Unit and Signal Aerial is
recommended).
4. Attach the coaxial cable to the Signal Aerial.
5. Run the coaxial cable from the Signal Aerial through the window
(an optional window entry kit is available: see page v) and to the
Base Unit.
6. Attach the Base Unit Aerial to the Base Unit and position it vertically.
7. Choose the appropriate power supply option for your location, connect the Power Supply to
the Base Unit and plug into a power outlet.
NOTE: If the red light starts flashing, try further separating the Signal Aerial and Base Unit,
disconnect power for 10 seconds and reconnect power or see the Troubleshooting section (Page 12) for
further information.
Upon initial power up, a solid GREEN light should appear indicating normal conditions. If a RED light

BEST PERFORMANCE: Attic/Outdoor placement
The following instructions are recommended for the best
reception:
1. Using your mobile phone as a signal meter, conrm
that either your attic or your roof will deliver optimal
signal strength to the Signal Aerial. Identify the best
location for attachment of the mounting bracket –
such as an attic cross or main beam.
2. Secure the mounting bracket at the highest possible
point and at least 1 meter away from metal objects
such as pipes, metal siding, A/C unit etc.
3. Position the mounting bracket such that the Signal
Aerial will be vertical and attach the Signal Aerial (see
gure 7).
4. Connect the supplied coaxial cable to the base of the Signal
Aerial.
5. Run the coaxial cable along a descending pipe or through a wall
that that leads closest to the location of the Base Unit.
NOTE: Refrain from securing cable or drilling holes until the system has been tested.
6. From the other end, connect the coax cable it to the Base Unit.
7. Connect the Base Unit Aerial to the Base Unit and position it vertically.
8. Choose the appropriate power supply option for your location, connect the Power Supply to
the Base Unit and plug into a power outlet.
NOTE: If a red light appears, try further separating the Signal Aerial and Base Unit or see the Troubleshoot-
ing section (Page 12) for further information.
More on Routing the Coaxial Cable Along side an Attic Pipe
Locate a pipe that descends from the attic down to the desired
location of the Base Unit. Tie a weight to a pull string and lower the
weight down alongside the pipe. In the lower room, tie the pull-string

Improving Your Coverage Area
Positioning the Base Unit
For the widest possible signal area, it is recommended that you position the zBoost® YX520i Base Unit near
the middle of a room or mount it on an interior wall. is Base Unit uses an omni-directional aerial that
delivers signal in a circular pattern around the aerial.
If you decide to position the Base Unit on or near an outside wall, we recommend purchasing a Directional
Base Unit Aerial (Page v) to focus the signal in the direction of your choice.
e Base Unit can be mounted either directly on a wall or placed on a at surface (e.g., a bookshelf,
desk, end table, etc.). e Base Unit performs best when located at least 1-2 meters above the oor or
approximately the height of a mobile phone when it is typically in use (avoid placing the Base Unit on the
oor).
For best results, avoid placing the Base Unit Aerial within 1 meter of other cords, metal objects or other
wireless devices such as wireless routers or wireless access points.
Conrm at Your zBoost® is Working Properly
Perform the following steps to conrm that the unit is now working properly:
1. Unplug the Base Unit power cable.
2. Turn on your mobile phone and check the number of bars.
3. Plug the power cable into the Base Unit.
4. Hold your mobile phone about 2 meters from the Base Unit and then turn it on. Wait up to
1 minute for the mobile phone to register the signal coming from the Base Unit.
5. If the number of bars shows improvement, your zBoost® unit is working properly.
e Base Unit can also be easily mounted to a wall using the included mounting bracket hardware. e Base
When your zBoost® system is in place and fully connected, you should walk throughout the room and see
that you are able to reliably place calls.
Remember, coverage varies based on outdoor signal level, building construction, and aerial placement.
Coverage in adjoining rooms (next to, above, or below) will be reduced due to walls or ceiling/oors.
Should you desire to improve coverage, you may:
• Move the Base Unit and/or adjust the angle of the Base Unit Aerial.
• Move the Signal Aerial to a higher location in your attic or outside.
• Purchase a Signal Aerial Upgrade (see page v).
• Purchase a Base Unit Aerial Upgrade (see page v).
Cell phone signal bars are approximate and vary from
phone to phone. e number of bars can uctuate widely,
depending on the location of the phone, the position or
angle of the phone, weather, etc. Most cell phone signal
meters update every 6 to 10 seconds. An increase of only
one bar typically indicates a 4x to 10x signal increase.
THE BEST INDICATOR OF PRODUCT
PERFORMANCE IS THE ABILITY TO RELIABLY
PLACE AND RECEIVE CALLS WHERE YOU COULD
NOT BEFORE SETTING UP THE YX520-I.
Note
Wall Mounting the Base Unit
Perform the following steps to mount the Base Unit to a wall:
1. Remove the mounting bracket from the Base Unit by rmly spreading one of the tabs
outward from the base unit as illustrated in gure 8.
2. Fasten the mounting bracket to the wall using the included wall/ceiling anchors.
3. Snap the Base Unit into the mounting bracket.

Frequently Asked Questions
What can I expect my cell phone signal range and strength to be inside my home or office?
e closer you are to the base, the stronger the signal. is will vary with dierent conditions. Some of the
conditions that will aect the improved coverage area are signal strength outdoors, the type of building
materials in the home, the placement of the unit and the antenna’s proximity to cellular towers.
You can expect that your indoor coverage will be improved. You will be able to make calls where you couldn’t
before. e degree of improvement will depend upon many factors. e intent of zBoost® products are to
bring outside coverage inside. Just as the signal bars move up and down when outside, the boosted signal
will uctuate in a similar fashion.
Is a cellular phone signal booster the same as a wireless router; will it help my WiFi signal?
e Wi-Ex® unit will not help your WiFi service. is unit is designed to work with wireless PCS and
Cellular phones and devices. e WIFI in your home or oce operates on a dierent frequency.
Is your product available for international use?
e YX520i is the international model.
We also sell zBoost® ONE YX400-U for UMTS/HSPA devices on the 2100MHz Frequency, a frequency
used for voice and data overseas.
Check the frequencies for a particular country for compatibility. Check our website www.Wi-Ex.com for
product availability.
Why isn’t my cell phone indicating more signal with more bars?
You may not always observe more bars that gain on your signal meter because of the signal spreading out
from the antenna. If your phone has a dB meter, 3dB is a signicant increase of 2x, 6dB is 4x, and 10dB is
10x. On a four bar phone, one "bar" equals about 10dB.
e increase in signal you will see depends upon:
• e level of signal at the Signal antenna (outdoor)
• e care of the antenna placement (two feet away from metal, adequate antenna separation [15 feet
recommended])
• e signal already present inside (related to building losses)
• e distance of your phone/device from the Base Unit (signal spreads or diminishes rapidly with dis-
tance.)
There are usually several cell phones in use at one time in my home, will your product boost all of our
signals simultaneously?
e zBoost® YX520-I is designed to cover multiple signals simultaneously and will allow multiple users to
operate at the same time.
Does the zBoost® work if you have no bars?
No, if no signal is present outdoors zBoost® producs will not work for you. Also, keep in mind if your best
signal is 1 bar at the Signal Antenna, your coverage will be limited to a small room. You could improve that
with an upgraded antenna. (See page iv).
