HOW TO ACTIVATE SART
1. Take off SART from the installation bracket.
2. Remove the black protector.
3. Pull off the red pin and rotate the operation handle to ON.
4. Check the LED indicator. While LED on, SART is ready to be triggered.
5. Keep SART as high as possible by using the telescopic pole supplied or hanging SART
in the life raft by using the rope supplied.
WARNING ：
Do not activate the SART unless in case of emergency. If the SART is activated for any
reasons, the battery pack in SART should be replaced to maintain enough life of batteries.
The red pin should also be replaced because it cannot restore to its right state after being
pulled off.

1. PRODUCT OUTLINE
The Search and Rescue Radar Transponder (SART) is avery simple 9GHz
receiver / transmitter which provides aposition.
The fundamental function of the SART is to indicate its position by producing
range and bearing information on any 9GHz radar screen of any nearby ship,
vessels and aircraft (with no modification).
When its RADAR receiver is triggered by an interrogating RADAR of 9GHz band
on asearch and rescue ship or aircraft, the SART immediately transmits acoded
response signal (aseries of 12 dots).
The SART code displayed on theradar screen is aseries of dots extending
radially outwards from the location of the transponder.
The series of dots represents arange of approximately 10 nautical miles. This
indication is an internationally accepted signal for search and rescue operations.
In addition, the SART gives confidence to survivors by giving aloud signal and
visual indication of the approach of assistance.

In operation, the SART responds automatically using a9GHz high-speed
frequency sweeping signal with apulse emission period of 100 ㎲which is
synchronous with any received scanning pulse.
The SART response signal scans all frequencies in the 9GHz radar band.
To select the SART code only on the radar screen, use the "detuning of the
radar receiver". This offset tuning erases all normal radar images caused by
echoes with the same frequency as the radar transmission.
However, the SART code is not erased because the SART response signal
scans all frequencies in the 9GHz band.

2. HOW TO ACTIVATE
①②③④
2.1 On vessel
When still onboard the vessel, activate SART as below:
⚫Take off SART from the installation bracket.
⚫Remove the black protector.
⚫Pull off the red pin and rotate the operation handle to ON.
⚫Check the LED indicator. While LED on, SART is ready to be triggered.
⚫Keep SART as high as possible by using the telescopic pole supplied.
⚫To close SART, move the operation handle to OFF.

2.2 In life raft
Activate SART in life raft as below:
⚫Keep SART as high as possible by using the telescopic pole supplied or
hanging SART in the life raft by using the rope supplied.
⚫Remove the black protector.
⚫Pull off the red pin and rotate the operation handle to ON.
⚫Check the LED indicator. While LED on, SART is ready to be triggered.
⚫To close SART, move the operation handle to OFF.

3. HOW TO TEST
⚫Take off SART from the bracket.
⚫Hold SART in open space outdoor.
⚫Remove the black protector.
⚫Pull off the red pin and rotate the
round operation handle to TEST.
⚫Check LED status. If LED on, the
SART is ready to be triggered.
⚫When the receiver of SART is
triggered by an interrogating
RADAR signal of 9GHz band on asearch and rescue ship or aircraft, the
SART immediately transmits acoded response signal (aseries of 12 dots),
which can be checked on RADAR screen.
⚫Rotate the round operation handle back to OFF and insert the black protector and
then place SART back to the bracket.
CAUTION：
Even in low output power, SART transmission can be well received by vessels nearby.
Frequent tests should be avoided not only for interference but also for battery-saving.
Don’t pull the red pin when test. The red pin can not be restored to its original status
after pulled. Pull the pin only when activate SART in emergency.

4. HOW TO MOUNT
SART is mounted with the wall bracket in the bridge. The bracket should be mounted in a
vertical position and in a place where SART is easily available in case of an emergency.
SART is mounted in such a position to avoid direct sunshine and heating source.
Fit the black bracket on the wall using four screws supplied, and then insert the SART into
the bracket.
Before inserting SART, OPEN the cap of the pipe, put the pipe into the black hole on
SART from upside and then cover the cape on the pipe.

5. PERIODIC INSPECTION
Periodic inspection is very important to ensure SART in a good condition. Each test should
be executed in short time because any test could reduce the life of the batteries.
5.1 Every six months
The inspection every six months years should be carried out by operators on board. The
inspection should cover the following items:
-Carry out test procedure by following HOW TO TEST.
-Check whether any damage can be viewed.
-Check the expiry date of the batteries.
-Record the inspection result.
5.2 Every five years
The inspection every five years should be carried out by manufacturer or authorized dealers.
The inspection should cover the following items:
-Replace the battery pack together with the case and gasket.
-Check the watertightness of the case.
-Carry out complete performance test.
-Record the inspection result.

replaced before the expiry date.
The following items are to be replaced together:
-Radome case of batteries (with operation instruction printed on the case)
-Case cover
-Colorless indicator cover
-Gasket
-Two cells of batteries
All above items are combined into a battery module, NBT100S.
NSR guarantees the quality of NRT-1000 SART only when original NBT100S battery
module is supplied by NSR.
