OUTDOOR INSTALLATION WARNING
IMPORTANT SAFETY PRECAUTIONS:
LIVES MAY BE AT RISK! Carefully observe these instructions and any special instructions
that are included with the equipment you are installing.
IMPORTANT: Look over the site before beginning any installation, and anticipate
possible hazards, especially these.
CONTACTING POWER LINES CAN BE LETHAL.
Make sure no power lines are anywhere where
possible contact can be made. Antennas, masts,
towers, guy wires or cables may lean or fall and
contact these lines. People may be injured or killed
if they are touching or holding any part of equipment
when it contacts electric lines. Make sure there is NO
possibility that equipment or personnel can come in
contact directly or indirectly with power lines.
Assume all overhead lines are power lines.
The horizontal distance from a tower, mast or antenna to the nearest power line should be
at least twice the total length of the mast/antenna combination. This will ensure that the
mast will not contact power if it falls either during installation or later.
TO AVOID FALLING, USE SAFE PROCEDURES WHEN WORKING AT HEIGHTS
ABOVE GROUND.
• Select equipment locations that will allow safe, simple equipment installation.
• Don’t work alone. A friend or co-worker can save your life if an accident hap-
pens.
• Use approved non-conducting lasers and other safety equipment. Make sure all
equipment is in good repair.
• If a tower or mast begins falling, don’t attempt to catch it. Stand back and let
it fall.
• If anything such as a wire or mast does come in contact with a power line,
DON’T TOUCH IT OR ATTEMPT TO MOVE IT. Instead, save your life by call-
ing the power company.
• Don’t attempt to erect antennas or towers on windy days.
MAKE SURE ALL TOWERS AND MASTS ARE SECURELY GROUNDED, AND
ELECTRICAL CABLES CONNECTED TO ANTENNAS HAVE LIGHTNING ARRESTORS.
This will help prevent re damage or human injury in case of lightning, static build-up, or
short circuit within equipment connected to the antenna.
• The base of the antenna mast or tower must be connected directly to the

building protective ground or to one or more approved grounding rods, using 1
OAWG ground wire and corrosion-resistant connectors.
• Refer to the National Electrical Code for grounding details.
• Lightning arrestors for antenna feed coaxial cables are available from Hyper-
Link Technologies, Inc.
IF A PERSON COMES IN CONTACT WITH ELECTRICAL POWER, AND CANNOT
MOVE:
• DON’T TOUCH THAT PERSON, OR YOU MAY BE ELECTROCUTED.
• Use a non-conductive dry board, stick or rope to push or drag them so they no
longer are in contact with electrical power.
• Once they are no longer contacting electrical power, administer CPR if you are
certified, and make sure that emergency medical aid has been requested.

Preparations
In order to obtain the best performance of booster and system, user must calculate
the transmission power to meet the booster technical requirement and FCC regulations.
Please follow the calculation below:
1. Convert power of the radio device from milliwatt to dBm.
 NOTE: dBm = 10 * Log (milliwatt)
2. Estimate the attenuation of cable (please refer to manufacturer’s specifica-
tions)
 NOTE:
It is suggested that the cable loss between booster and DC
injector should not exceed 10 dBm.
General Cable Attenuation List
LMR400 LMR600 LMR900
dB loss per meter 0.221 0.144 0.098
Suggested max. cable length (m) 45.24 69.44 102.04
3. Calculate the actual power of booster in the pole as follow:
Radio Device Power (dBm) – Cable Loss (dBm) – Misc. Loss = Input Signal
Level (dBm)

3
 NOTE:
Misc. Loss means loss of connector, adapter and DC injector and
estimates to be around 2 dB.
4. When the input signal level exceeds the Receiver Input Power of booster, the
booster can’t identify the input signal. Under this circumstance, user should
lower the input signal level to fit the requirement such as using an attenuation
pad or a higher loss cable and vice versa.
Hardware Installation
Please follow the procedures below to install the booster kit.
1. Connect the booster RF output directly to the antenna with appropriate cable.
2. Attach the booster RF input to the DC Injector with coaxial cable.
Warning: The cable between DC injector and booster carries the DC voltage
and should not be connected to devices other than booster.
3. Connect the coaxial cable leading from the DC Injector to the antenna on the
radio device such as Access Point.
4. Plug the power cable leading from the DC Injector into any available 110/220
V electrical outlet.
5. Check the LED indicator of the DC injector. If the LED is on, it means the booster
kit is operating.

Troubleshooting
If there is no signal output, please check the following item:
1. Check whether the LED indicator on the DC injector is on. If not, it means there
is problem with the power component.
(1) Check if the power cord is correctly connected with the power adapter and
the power outlet.
(2) Check if there is electricity on power outlet.
2. Check if the radio device is working properly.
3. Check if the connection between booster and DC injector is correct, or whether
the connector is loose or not.
4. Verify if the transmit power which calculated before is correct.
5. If none of the above measures could solve the issue, please contact the supplier
for further support.
