For Safe Operation
Symbol used in this Operation Manual
This Operation Manual uses the following symbols. Understand the meaning of each symbol and
implement the maintenance and inspections given.
Symbol Meaning
Warning mark
Handle correctly. Otherwise, it may lead to death or serious injury.
High Voltage Caution mark
Handle correctly. Otherwise, electrocution may occur, which could result in
death or serious injury.
Caution mark
Handle correctly. Otherwise, it may lead to light injury or damage to the
equipment.
Prohibit Mark
This mark indicates that the specific action is prohibited. The inhibited
action is displayed around the mark.
Cautions and Warnings on Equipment
Be careful of rotating aerial.
The radar may start to rate without notice. For safety, keep away from the
radar.
Be careful of high frequency interference
Strong electromagnetic wave is radiated from the antenna. If the
electromagnetic wave is continuously radiated, human bodies may be
affected. The international law defines that the electromagnetic wave of a
power density of below 100W/m2 does not affect human bodies.
However, a medical appliance such as pacer maker may become unstable
due to small amount of power of electromagnetic wave.
In any cases, a person wearing such appliance should not be allowed
access to a place where the electromagnetic wave is radiated,

For Safe Operation T-900 series

Be careful of a high voltage inside.
A lethal high voltage is used. This high voltage remains in the circuit after
you have turned off the power switch. To prevent touching the high voltage
circuit inadvertently, the protective cover is provided to the high voltage
circuit and the high voltage caution label is affixed. Be sure to turn off the
power switch for your safety and discharge the electricity remaining in the
capacitor before starting inspections. Only an engineer authorized by
SI-TEX should providesinspections and maintenance.
Be sure to turn off the power of the boat.
If the power switch is inadvertently turned on during work, lethal
electrocution could occur. To prevent such an accident from occurring, be
sure to turn off the power of the boat and the power of the equipment.
Furthermore, it is safer to hang a caution tag described as [Under Work]
near the power switch of the equipment.
Be careful of dust
Inhaling dust may cause a respiratory problem. When cleaning the inside of
the equipment, be careful not to inhale dust. Wearing a safety mask is
recommended.
Caution on location of equipment
Do not install the equipment where it is excessively damp and exposed to
water spray or dripping. The inside of the unit may be misted and the inside
may be corroded.
Preventing from static electricity
Static electricity may be generated from the carpet on the floor in the cabin
or clothes made of synthetic fiber. Static electricity can damage the
electronic parts in the circuit board. Be sure to take appropriate measures to
disseminate any static electricity from your body before handling the circuit
board.

T-900 series For Safe Operation
0093142132-00 v
Cautions and Warnings on Handling
Do not disassemble or modify. Otherwise fire, smoking or electric shock could occur. In case of trouble,
contact your dealer or SI-TEX.
In case of smoking or fire, turn off the boat power and the power of this
unit. Otherwise, fire, electric shock or damage could occur.
The information displayed in this unit is not provided directly for your
navigation. For your navigation, be sure to see the specified material.
Use the specified fuse. If un-specified fuse is used, it may cause a fire,
smoking or damage.
Caution on Display Unit
Do not push or scrub the surface of the display unit with a pointed tip of a
hard matter (tool, tip of a pen, etc) Scars could be made.
Do not press the surface of the display unit. Interference stripes or display
abnormality could occurs.

Introduction
Thank for yourpurchase of SI-TEX color LCD radarT-900 series.
The quality and endurance of a unit is well considered. For the best performance, read this Operation
Manual and operate a unit correctly and safely.
The main features of this unit are as follows.
•The high performance radar equipped with 8.4 inch display can be used for professional use.
•In the true trail function, as moving targets such as other ships are displayed being tailed and
stationary targets such as land are displayed being fixed, the moving targets and fixed targets can
be easily discriminated.
•Two screen images of different ranges can be displayed. If you set a near distance screen and a far
distance, you can navigate properly and grasp a situation.
•The automatic tracking function (ATA) is provided. The maximum 50 targets can be tracked. The
current motion of other ships can be grasped in a vector and numeral so that it helps your ship to
navigate safely. (Optional)
•By connecting the AIS receiver, the gathered information such as name, heading and speed of a
ship can be displayed. (Optional interface)
•With the adoption of a specific filter (AR coat), an image can be seen clearly, refusing sunshine. The
countermeasures against the reflection on the LCD screen and dew are provided.
•The RGB output for an external monitor is provided as standard equipment. The use of the external
monitor enables you to observe easily the radar screen at a location which is remote from a main
unit. (External monitor: Prepared by a customer)
•A video from a CCD camera can be displayed. The inside of a ship can be observed by a camera
installed at the engine room helps your ship navigate safely. (CCD camera: Prepared by a customer)
•With the adoption of the gain/STC rotary knob, the operability is enhanced.
•When flush-mounted, a unit can be installed or removed from the front of the unit.

Chapter 1 Basic Operation
The basic operation of this unit is as follows. For detailed explanation, refer to each item in this manual.
1.
1.3 Power On/Off
2.
1.5 Transmission
1. Press the [BRILL] to turn
on the power.
When [ST'BY] appears, press
the [STBY/TX] key to start
the transmission.
5. Rotate the [STC] knob to adjust the sea surface reflection suppression effect.
The suppression effect becomes strong when rotating clockwise the knob and
becomes weak when rotating counterclockwise the knob.
・This function reduces the gain at a near distance. If you turn clockwise the knob
too much, desired objects may disappear. Adjust properly to meet the weather
condition.
Example of STC adjustment :
: The suppression
is too weak.
: Optimum
suppression.
The reflection from sea
surface is displayed.
The desired objects
are displayed.
:Thesuppression
is too strong.
Some objects are
not displayed.

Change the observation range with the [- RANGE +] key.
When pressing the [+] key, the observation range expands.
When pressing the [-] key, the enlarged surrounding around own ship can be observed.
To make it easier to observe the range you desire, change the range.
Example of display :
Long range : Far distance Middle range : Middle distance
Objects at far distance
can be covered.
Short range : Near distance
Objects near own ship
can be easily confirmed.

Example of gain adjustment:
: Too high gain
Noise is also displayed. Desired targets are
displayed.
Some targets are not
displayed.
: Optimum gain : Too low gain
1.7 Gain adjustment
The gain becomes high when rotating clockwise the knob and becomes low when rotating
counterclockwise the knob.
When the observation range is narrow or targets are crowded, reduce the gain so that
targets can be easily seen.
When the observation range is wide, if the gain is increased, it is effective.
But, due to noise increase, small targets become hard to be seen.
