WARNING
Klein Marine Systems recommends all troubleshooting be done by
a trained technician. Some circuits in the Sonar Transceiver and
Processing Unit have voltages as high as 240 volts, and some
circuits in the sonar towfish have 1500 volts. You should
familiarize yourself with the location of these voltages before you
attempt any troubleshooting. Failure to observe these warnings
could result in injuries to personnel.
CAUTION
Serious damage to the sonar electronics may occur if the sonar
towfish is operated out of the water for periods longer than 15
minutes. Let the sonar cool 15 minutes or longer between
operations. Protect the sonar towfish from direct exposure to the
sun prior to and during operation in high temperature climates.
CAUTION
The depth rating on the transducers is 200 meters (656 feet).
Operations at depths greater than 200 meters may damage the
transducers.
CAUTION
When the towfish is close to the sea floor, the 900-kHz bottom
tracking (altitude) performance is not exact. Klein Marine Systems
advises extreme caution when operating the towfish at altitudes of
less than 4 meters (13 feet).

CHAPTER 1: OVERVIEW
The Series 3900 Sonar System is a dual frequency, very high resolution, long
range side scan sonar system, ideally suited for search and recovery missions and
other surveys which require high accuracy in shallow water environments. The
system is lightweight, one-man portable and specially configured for simple setup
and operation from a small boat.
1.1 Equipment
The Series 3900 Sonar System equipment consists of a single beam sonar
instrumented towfish, a splashproof transceiver and processing unit, and a laptop
computer, along with a tow cable and various interconnect cables.
1.1.1 Single Beam Sonar Instrumented Towfish
The towfish electronics perform all the sonar data processing prior to digital
transmission to the transceiver and processing unit. This minimizes the system’s
susceptibility to externally induced electronic noise. Processing includes transmit/
receive functions, time varied gain (TVG) amplification, digitalization, and
multiplexing of the sonar uplink data. Timing and sonar data are bidirectionally
multiplexed on a single conductor coaxial cable. Use of a low noise preamplifier
design ensures maximum range performance. The ability to operate with a
fiber-optic cable is available as an option for very long cable (deep tow) operations
or installations requiring electrical isolation in severe noise environments.
An electro-mechanical termination is provided on the towfish end of the tow cable
for connection to the towfish. A tow shackle provides a strong, reliable,
mechanical termination to the towfish tow bracket. An underwater connector on a
pigtail connects the tow cable electrically to an underwater jumper cable on the
towfish.
1.1.2 Splashproof-II Transceiver and Processing
Unit (SP-II TPU)
The transceiver and processing unit is a Splashproof-II TPU (SP-II TPU) which
contains the electronics for processing the sonar data and powering and
communicating with the towfish.

1.1.3 Laptop Computer
The laptop computer supports the PC based Windows operating system as the
display and control interface. This provides for an easy to use familiar graphical
user interface and simple expansion capabilities to a wide assortment of
equipment. The software is set up in a client-server format, allowing for flexible
and expandable system configurations with multiple computers connected over a
TCP/IP fast Ethernet network, all sharing the sonar data.
1.1.4 Tow Cable
Coaxial tow cable is used to transmit data bidirectionally from the towfish to the
SP-II TPU.

Physical Description 1-3
1.3 Physical Description
The Series 3900 Sonar System consists of two major subsystems: the surface
equipment and the subsurface equipment.
1.3.1 Surface
Equipment
The surface equipment
comprises the SP-II TPU and
the laptop computer.
SP-II TPU. The SP-II TPU
is shown in Figure 1-1. The
SP-II TPU is built into a
rugged, lightweight
splashproof case and
contains the electronics for
powering the towfish,
downlink multiplexing the
control signals to the
towfish and uplink
demultiplexing the sonar
and sensor data from the
towfish. All of the
connectors, indicators and
switches are splashproof
and are located on a panel
on the side of the unit. The
SP-II TPU is powered from
either an AC or DC power source which is operator selectable with a switch on
the side panel.
Laptop Computer. Most operator functions are accomplished through the use
of the laptop computer which runs SonarPro, a comprehensive Klein Marine
Systems Windows based software program that provides multiple displays of
real-time or saved sonar and sensor data and towfish status. For information
about the laptop computer, refer to the manufacturer's manual for it.
CAUTION Do not submerge the SP-II TPU in water as it is not designed
for continuous immersion.

1.3.2 Subsurface Equipment
The subsurface equipment comprises the towfish, as shown in Figure 1-2, and a
tow cable.
Towfish. The Towfish consists of a negatively buoyant tow body containing
port and starboard sonar transducers, processing and control electronics for
sonar operation, a downlink demultiplexer for control signals, and an uplink
multiplexer for sonar and sensor data.
Tow Cable. The tow cable is a complete assembly consisting of a coaxial tow
cable with a copper conductor, an electro-mechanical termination on the
towfish end, and an electrical underwater connector. The tow cable is available
in a lightweight polyurethane jacketed Kevlar reinforced design. The
lightweight design is used for operations with cable lengths of 300 meters and
under.
