Test Installation -MUST BE READ
Where to install the outside antenna? The position,
where the outside antenna is installed, it can bring a
significant impact on the booster performance.
To point directly the cell tower, it aims to receive the best
signal and prevent the signal interference.
The higher position, it might avoid the impact caused by
the big obstruction between the house and the cell
tower.
ATTENTION: If the house is metal siding, do NOT install
the outside antenna or the outside unit directly on it.
Keep minimum 50 cm ( 1.6 ft ) distance.
When installing the booster and the antennas, we do
require Minimum Separation Distance between the
outside antenna and the inside antenna.
Minimum Required Separation Distance：
6 meters (20 ft ) distance and 1.5 meters ( 5 ft ) vertical
height distance. (see Self Oscillation section)

Test Installation:
Doing a test installation of a cell phone booster, it allows you to experiment different scenarios to
determine your optimal system setup. SolidRF STRONGLY recommends doing a test installation
before the permanent installation.
Why?
1. To decide where to place the outside antenna, the booster and the inside antenna.
2. To determine routing the cable
inside the house.
3. Doing a test installation will simplify
the process if the system you
purchased was not ideal for your
situation. In this event, please contact
us by email, [e-mail]

STEP BY STEP INSTALLATION
Step 1: Mount the outside antenna
a. Choose right position
•Find the strongest signal position in the
possible install locations by reading your cell
phone signal bar (see Find Strongest Signal)
•30 cm away from any other metallic objects
•100 cm away from any windows
b. Mount the antenna pole
c. Mount the antenna to the pole
Caution: The inside and outside antennas can
NOT directly face each other. This will result in
possible self oscillation. (see self oscillation
section)
d. Connect the outside cable to the outside
antenna
•Make sure connectors are well screwed in
•Seal the connectors with glued tape
Installation -Step By Step
How does it works
Step 1: The powerful outside antenna captures
a voice and data signal and transfers it to the
booster.
Step 2: The booster receives the signal,
amplifies it and then rebroadcasts the signal by
the inside antenna.
Step 3: Your mobile devices will get a better
signal, never experiencing dropped calls or slow
data speed.

Conduct a Test Installation
Conduct a test instillation to ensure correct
product functioning before permanently
installing the booster.
The test instillation will help to determine the
best location for the inner and outer antenna
and additionally the routing cable

b. Connect the outside antenna’s connector to
the port labeled “OUTSIDE” on the booster
c. Connect the inside antenna’s connector to
the port labeled “INSIDE” on the booster
Step 4: Power on the booster
•Plug the power adapter into the power port
on the booster.
•Then plug into a surge protector power strip.
WARNING:
•Do NOT cover the booster body with
anything. This prevents if from cooling
down. If the product becomes overheated,
it will automatically shut off or cause
permanent damage.
•Use only the power supply provided by
SolidRF. Any other non-approved products
by SolidRF of self-made power cables may
damage the booster.
•Connecting the booster directly to the cell
phone with use of an adapter will damage
the cell phone.
•The booster is designed for use in indoor
O N LY.
•Ensure that neither you nor the pole comes
near any power lines during installation.
Installation -Step By Step
e. Set the outside antenna cable into the
building
•Carefully arrange the cable along the outside
of the building and ensure that there are no
folds or kinks
•Fix the cable at each corner
Step 2: Mount the inside antenna
a. Choose right position
•20 cm away from any other metallic objects
•50 cm away from any windows
•The inside antenna should be facing the
location of the signal dead zone/weak signal
area inside the building
b. Mount the inside antenna
c. Connect the inside cable to the inside
antenna
Step 3: Arrange the booster
a. Choose position
•Be sure to be far from any heat source
•In a ventilated dry place, temperature range
should be from -5 ℃to +50 ℃

Technical Specification
This device complies with Part 15 of FCC rules. Operation is subject to 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. Changes or modifications not expressly approved by SolidRF could void the authority to operate
this equipment.
RF Exposure: The manufacturer’s rated output power of this equipment is for signal 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
is reradiated 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 attenuating at the output of the device.

This is a CONSUMER device.
BEFORE USE, you MUST REGISTER THIS DEVICE with your wireless provider and have your provider’s
consent. Most wireless providers consent to the use of signal boosters. Some providers may not consent
to the use of this device on their network. If you are unsure, contact your provider.
You MUST operate this device with approved antennas and cables as specified by the manufacturer.
Antennas MUST be installed at least 20 cm (8 inches) from any person.
You MUST cease operating this device immediately if requested by the FCC or a licensed wireless service
provider.
WARNING. E911 location information may not be provided or may be inaccurate for calls served by
using this device.
WARNING:
•The outside antenna must be installed no higher than 10 meters (32’9”) above ground.

ATTENTION: Self Oscillation
We strongly recommend it must achieve the Minimum Required Separation Distance for the
installation. The improper installation could result in possible Self Oscillation.
Minimum Required Separation Distance (MRSD)：6 meters (20 ft ) distance and 1.5 meters ( 5 ft )
vertical height distance.
When the antennas are too close, they
could pick up each others signals,
creating a feedback loop condition,
which is called Self Oscillation.
By FCC regulations, the cell phone
booster would automatically detect this
condition and immediately shut down to
prevent Self Oscillation from damaging
the cellular network.
What is Self Oscillation:
If the booster detects Self Oscillation, it
will not operate until the condition is
corrected. One way to correct Self
Oscillation is to increase separation
distance between the antennas until the
good separation distance is achieved.
Also the antennas can NOT directly face
each other.
How to correct Self Oscillation:
The Self Oscillation could cause interference to the cellular network, The FCC regulations
extremely prohibit cell phone booster users from causing interference to the cellular networks. If
you were contacted by the FCC or any wireless provider – yours or any other – and told your cell
phone booster is causing interference, you must shut it down until you can fix the interference
problem. Under most situation, it is Self Oscillation problem.
Please refer to:
https://www.fcc.gov/wireless-telecommunications/signal-boosters/faq/signal-boosters-faq.
Why is it so important to prevent Self Oscillation:

Troubleshooting
Find Strongest Signal
Correct functioning:
The lights on the control panel indicate the condition of the booster. Every time the booster is
powered on, all of the lights will be green in color for several seconds then off. This means the
booster has passed the self check and is in good condition.
Incorrect functioning:
•If any of the lights on the control panel are flashing in green, it means that self oscillation is
occurring. You must switch off the booster and check the outside and the inside antennas
immediately. Make sure you have followed the recommended installation process and check
each step carefully. Refer to Self Oscillation section for more details of minimum required
separation distance and antennas installation. See the control panel instruction: how to adjust
the gain (output power) to prevent possible self oscillation. If you can not fix the problem please
contact the technical support or the reseller.
•If the power light is flashing, please contact the technical support.

Use Cell Phone Only:
•Check the signal indicator on the cell phone display, it takes up to 30 seconds to reset a new
reading. Or place calls from several locations outside the building.
•Read signal strength with numerical value (Smart Phone Only):
iPhone: Dial *3001#12345#* then tap the CALL button, a negative number in the upper left
corne r.
Android Phone: Go to Setting – About Phone – Status (SIM Status) – Signal Strength
It would a negative number instead of the five dots, the range is from -120 (weak) to -65 (strong)
Use Cell Phone During Test Installation:
•One person adjusts the outside directional antenna small angle at a time. Allow 30 seconds for
the phone to react with each turn.
•Second person read the signal strength on the cell phone inside the building.
