To satisfy FCC RF exposure requirements for transmitting
devices, a separation distance of 100 Centimeters or more
should be maintained between the UPLINK antenna of this
device and persons during device operation. To satisfy FCC
RF exposure requirements for transmitting devices, a separation distance of 30 Centimeters or more should be maintained between the DOWNLINK antenna of this device and
persons during device operation. To ensure compliance,
operations at closer than these distances is not recommended.
The antenna used for this transmitter must not be co-located
in conjunction with any other antenna or transmitter.
WARNING
For Class A Unintentional Radiators
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Changes or modifications not expressly approved by TX
RX System Inc. could void the user’s authority to operate
the equipment.
WARNING
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following 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.

Antenna System Installation
The antenna or signal distribution system consists of two branches. An uplink
branch typically uses an outdoor mounted, unidirectional gain antenna such
as a yagi and a downlink signal radiating system consisting of a network of
zero-gain whip antennas or lengths of radiating cable usually mounted inside
of the structure.
Even though the antenna system may not be supplied or installed by TX RX
Systems. The following points need to be observed because both the safety
of the user and proper system performance depend on them.
1) Antenna system installation should only be performed by qualified technical personnel.
2) The following instructions for your safety describe antenna installation
guidelines based on FCC Maximum RF Exposure Compliance requirements.
3) The uplink antenna is usually mounted outside and exchanges signals
with the repeater base station or donor site. It is typically mounted permanently-attached to the building wall or roof. The gain of this antenna should
NOT exceed 10 dB. Only qualified personnel should have access to the
antenna and under normal operating conditions, no one should be able to
touch or approach it within 100 Centimeters (40 inches).
4) The downlink or in-building signal distribution system is connected to the
downlink booster port using coaxial cable. The distribution system may
use radiating coaxial cable or a network 1/4 wave whip antennas whose
gain does not exceed 0 dB for any radiator. These antennas should be
installed so that the user cannot approach any closer than 30 Centimeters
(12 inches) from the antenna.

GENERAL DESCRIPTION
Signal boosters extend radio coverage into areas
where abrupt propagation losses prevent reliable
communication. This system receives an RF signal, raises its power level, and couples it to an
antenna or leaky (radiating) coaxial cable system
so that it can be re-radiated. No frequency translation (conversion) occurs with this device. The twoway signal booster 61-65-50-XXX-XX is a broadband, bidirectional, dual branch (uplink and downlink) system available in 5.0 MHz passbands. The
booster passes uplink and downlink signals from
406 to 430 MHz. The booster is available in a variety of configurations as listed in Ta bl e 1. A front
view of the booster is shown in Figure 1.
Linear RF active amplifiers, filters, and DC power
sources are used to adequately boost and re-radiate the passband signals. Amplifier stages used in
this signal booster system may be damaged by
excessively strong input signal levels. To minimize
this the system is equipped with Output Leveling
Circuitry (OLC) to protect the amplifiers and reduce
spurious signals.
The system can be ordered in one of three maximum gain configurations including Full Gain (+80
dB gain max), Medium Gain (+60 dB gain max),
and Low Gain (+45 dB max gain). The maximum
gain of the system is determined by the exact type
of cards plugged into the low level and mid level
slots. The maximum gain of the uplink or downlink
branch is adjustable and can be setup independently. In addition, the gain of each branch can be
reduced up to 30 dB in 0.5 dB increments via software interface.
Three cabinet styles are available. The G1 suffix
denotes a NEMA-4 style cabinet which is suitable
for indoor or outdoor use. The G2 suffix denotes a
stainless steel NEMA-4X style cabinet suitable for
corrosive environments such as salt air and the RM
suffix a rack mount version which is intended for
indoor mounting only.
UNPACKING
It is important to report any visible damage to the
carrier immediately. It is the customer's responsibility to file damage claims with the carrier within a
short period of time after delivery (1 to 5 days).
Care should be taken when removing the unit from
the packing box to avoid damage to external heatsink fins. Use caution because the heatsink fins
can have somewhat sharp corners. Signal Booster
II (SB II) weighs in excess of 205 pounds so use
enough people when lifting the unit.
INSTALLATION
The following sections discuss general considerations for installing the booster. All work should be
performed by qualified personal in accordance with
local codes.
Location
The layout of the signal distribution system will be
the prime factor in determining the mounting location of Signal Booster II. However, safety and serviceability are also key considerations. The unit
