1. SAFETY AND REGULATORY INFORMATION
1.1 SAFETY SYMBOL CONVENTIONS
The following conventions are used throughout this manual set to alert the user to general safety
precautions that must be observed during all phases of installation, operation, service, and repair of this
product. Failure to comply with these precautions or with specific warnings elsewhere in this manual set
violates safety standards of design, manufacture, and intended use of the product. M/A-COM, Inc.
assumes no liability for the customer's failure to comply with these standards.
The WARNING symbol calls attention to a procedure, practice, or the like, which,
if not correctly performed or adhered to, could result in personal injury. Do not
proceed beyond a WARNING symbol until the conditions identified are fully
understood or met.
The electrical hazard symbol indicates there is an electrical shock hazard present!
MM-009290-001
The CAUTION symbol calls attention to an operating procedure, practice, or the like,
which, if not performed correctly or adhered to, could result in damage to the
CAUTION
equipment or severely degrade equipment performance.
The NOTE symbol calls attention to supplemental information, which may improve
system performance or clarify a process or procedure.
The ESD symbol calls attention to procedures, practices, or the like, which could
expose equipment to the effects of Electro-Static Discharge. Proper precautions must be
taken to prevent ESD when handling circuit modules.

MM-009290-001
1.2 MAXIMUM PERMISSIBLE EXPOSURE LIMITS
DO NOT TRANSMIT with this base station and its antenna when persons are within the MAXIMUM
PERMISSIBLE EXPOSURE (MPE) radius of the radio frequency (RF) antenna. The MPE radius is the
minimum distance from the antenna axis that ALL persons should maintain in order to avoid RF exposure
higher than the allowable MPE level set by the FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS
WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION
ABSORPTION, WHICH EXCEEDS THE FCC MAXIMUM PERMISSIBLE
EXPOSURE (MPE) LIMIT. IT IS THE RESPONSIBILITY OF THE BASE
STATION OPERATOR TO ENSURE THAT THE MAXIMUM PERMISSIBLE
EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES DURING BASE
STATION TRANSMISSION. THE BASE STATION OPERATOR MUST
ENSURE NO BYSTANDERS ARE WITHIN THE MPE RADIUS LIMITS
WHEN THE STATION IS TRANSMITTING.
1.3 DETERMINING MPE RADIUS
THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS is unique for each site and is determined
during site licensing time based on the complete installation environment (i.e. co-location, antenna type,
transmit power level, etc.). Determination of the MPE radius is the responsibility of the installation
licensee. Calculation of the MPE radius is required as part of the site licensing procedure with the FCC.
1.4 SAFETY TRAINING INFORMATION
THIS BASE STATION GENERATES RADIO FREQUENCY (RF) ELECTROMAGNETIC ENERGY WHEN IT IS TRANSMITTING. THIS BASE STATION
IS DESIGNED FOR AND CLASSIFIED AS “OCCUPATIONAL USE ONLY,”
MEANING IT MUST BE USED ONLY IN THE COURSE OF EMPLOYMENT
BY INDIVIDUALS AWARE OF THE HAZARDS AND THE WAYS TO
MINIMIZE SUCH HAZARDS. THIS BASE STATION IS NOT INTENDED
FOR USE BY THE “GENERAL POPULATION” IN AN UNCONTROLLED
ENVIRONMENT. IT IS THE RESPONSIBILITY OF THE BASE STATION
OPERATOR TO ENSURE THE MAXIMUM PERMISSIBLE EXPOSURE
LIMITS ARE OBSERVED AT ALL TIMES DURING STATION
TRANSMISSIONS. THE BASE STATION OPERATOR IS TO ENSURE THAT
NO BYSTANDERS COME WITHIN THE RADIUS OF THE MAXIMUM
PERMISSIBLE EXPOSURE LIMITS.
When licensed by the FCC, this base station complies with the FCC RF exposure limits when persons are
beyond the MPE radius of the antenna. In addition, the M/A-COM base station’s installation complies
with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels
and evaluation of such levels for exposure to humans:
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
6
• American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety Levels
with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300
GHz.
• American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for
the Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave.
TO ENSURE HUMAN EXPOSURE TO RF ELECTROMAGNETIC ENERGY IS
WITHIN THE FCC ALLOWABLE LIMITS FOR OCCUPATIONAL USE, DO NOT
OPERATE THE BASE STATION IN A MANNER THAT WOULD CREATE AN
CAUTION
MPE RADIUS IN EXCESS OF THAT ALLOWED BY THE FCC.
Changes or modifications not expressly approved by M/A-COM Inc. could void the
user’s authority to operate the equipment.

3.2 GENERAL INFORMATION
M/A-COM’s OpenSky® 700 MHz Cell Site base station is a stand-alone fully-digital trunked base station
for 700 MHz OpenSky trunked radio networks. Housed in a compact and easy-to-install weather-resistant
cabinet, it can be pole mounted, tower mounted or wall mounted. The Cell Site base station requires a colocated continuous-duty 24-volt DC power source, a 700 MHz antenna system, and site-to-site backhaul
communication equipment to link it to the high-power SkyMASTR base station/tower site.
OpenSky employs Time-Division Multiple-Access (TDMA) digital modulation technology. TDMA
allows multiple users to share a single RF channel. Each channel can support simultaneous digital voice
and data communications, in either a 2-slot or 4-slot format.
The Cell Site base station operates in the OpenSky Trunking Protocol (OTP) mode on a single 25 kHz
wide 700 MHz RF channel. A key advantage of OTP mode is its internet protocol (IP) based
communication capability. The station has a RF transmit output power range that is configurable between
15 and 37 watts (35 to 45.7 dBm), with a 25-watt continuous-duty rating.
The Cell Site base station complements the wide area coverage of a high-power SkyMASTR base
station/tower site by providing a cost-effective RF coverage solution for problem areas. It provides
consistent RF coverage to low-traffic areas that require only a single (2-slot or 4-slot TDMA) channel for
voice and data communications. Cell Site base stations are typically employed in areas that are problem
coverage areas for the respective high-power tower site(s). In other words, those areas hard-to-reach from
an RF standpoint via the high-power tower site(s) due to difficult terrain or other geographic or manmade RF obstructions. In essence, a Cell Site base station is an extension of a high-power tower site’s
network of OpenSky base stations. A Cell Site base station can typically be deployed for one-tenth the
cost of a tower site with an equipment shelter.

OpenSky system software up to release 4 utilizes 2-slot TDMA technology.
