FCC NOTICE
The SureCall Guardian4 signal booster is a 90.219 Class B Device. Under Section 90.219(d)(5) of the Commission’s
rules, all Part 90 Class B signal booster installations must be registered with the FCC. In February 2013, as part of the
Commission’s efforts to support the continued use of signal boosters in the Private Land Mobile Radio Services and Public
Safety Radio Services, the Commission adopted a registration requirement for existing and future Part 90 Class B signal
booster installations. The Commission found that a Class B signal booster registration system would be a valuable tool
to help resolve interference should it occur.
All Part 90 licensees and signal-booster operators must register existing Part 90 Class B signal boosters with the
Commission by November 1, 2014. In addition, any new Class B signal booster installed after November 1, 2014 must
be registered prior to operation.
Filing Registrations. To register a Part 90 Class B signal booster, go to the Part 90 Signal Booster Registration and
Discovery page at www.fcc.gov/signal-boosters/registration. Enter an FCC Registration Number (FRN) and Password in
the upper-right corner of the screen. Then click on “LOGIN.”
On the Signal Booster Information page, enter either (1) latitude and longitude (in decimal degrees) of the booster location
and click on the “Get Address Info” button; or (2) the booster, city, and state, and click on the “Get Lat/Long button. The
registration tool will provide a map of the booster location to verify the location is correct. Next, check the box(es) for the
frequencies within the operating range of the signal booster and enter at least one call sign associated with the booster.
Then enter the ler’s Company Information (Company Name, Company Attention, Address, Email registration, enter
Signature Information (Title, Name), and click “Submit.” The system will generate a conrmation, including a booster ID
number, which you may print for your records. Each booster must be submitted separately. Using the links in the upper-
right corner of the Signal Booster Conrmation page, you can “Add a Booster,” “View Your Boosters” or “Log out.”
Accessing Registrations. Each registration will be available to the public on the same day it is led with the Commission.
Registrations may be accessed at: www.fcc.gov/signal-boosters/registration. Click on “View All Boosters” from the Part 90
Signal Booster Registration and Discovery page. The registrations can be searched and sorted by booster ID number,
name of the ler, city, county, state, zip code, latitude/longitude, or call sign.
For further information please contact the FCC Licensing Support Hotline at [phone] or submit an online help
request at https://esupport.ffc.gov/onlinerequest.htm. Support hours are Monday thru Friday, 8:00–6:00 p.m. Eastern
Time, except for Federal holidays.

1.6 How it Works
The Guardian4 amplies signals that reach a building from the nearest radio tower, and from radios inside the
building going back to the tower. This compensates for weak reception caused by distance, topography, building
structure, etc. The BDA receives the signal from an outside antenna, amplies that signal, and then rebroadcasts it
via antenna(s) inside the building, where it can then be picked up by radios inside. In the reverse direction, interior
antennas also pick up signals coming from radios, where they are amplied by the BDA, and then passed to the
exterior antenna for rebroadcast back to the tower.
1.7 Single vs. Multiple Carrier Operation
SureCall’s rated output power of this equipment is for single-carrier operation. It is recommended that you factor in
loss when dealing with multiple carrier signals. We suggest 3 to 5 db loss factor.
1.8 A Word About Safety
Follow all safety precautions in this manual. This information is designed to prevent personal injury, equipment
malfunction, and/or radio interference. You are responsible for ensuring a safe installation.
Your installation may require working in high locations such as roofs and/or ladders. Follow applicable safety
regulations and best practices to avoid falling. Take care not to drop objects from any high area. Cordon off ground
areas directly below the section of roof you are working on, or below your ladder whenever possible.
In addition, as a qualied installer, you are responsible for knowing and following all applicable codes and regulations
and for obtaining all required permits and inspections.
Always use appropriate personal protective equipment such as goggles, gloves, hard hat, etc. as needed, and as
required. Failure to exercise caution when working in high areas could cause a fall and personal injury.
.
RF SAFETY WARNING: ANY ANTENNA USED WITH THIS
DEVICE MUST BE LOCATED AT LEAST 8 INCHES FROM
ALL PERSONS.
CHANGES OR MODIFICATIONS NOT EXPRESSLY
APPROVED BY SURECALL COULD VOID THE USER’S
AUTHORITY TO OPERATE THE EQUIPMENT.
