Precautions (FFC)
WARNING
If the false distress alert is transmitted, take the following instructions immediately.
(1) Stop the transmission immediately.
(2) Report the following information to the Maritime Safety Agency.
(a) Ship’s Name, Type and Flag
(b) Capsule ID number (15 character UIN):
(c) Position and Time at the false transmission
(d) Cause of the false transmission
(e) Type, Serial Number and Delivery Date of the capsule
Do not pull up the capsule from water during distress.
If the capsule is taken out from water in distress, it stops sending distress signals.
The capsule EPIRB function must not be used for other than distress.
Otherwise, a large trouble will be given to the search rescue organization.
Do not set the switch to "ON" except the case of manual activation in distress.
Distress signals are transmitted when turning the switch "ON".
The capsule unit must not be taken out from bracket other than distress.
Otherwise, a large trouble will be given to the search rescue organization.
The selector switch must be set to the “READY” position while voyaging.
The hydrostatic release unit (HRU) activates the cutter using spring force. Do not disassemble the
HRU, nor apply pressure to it. Serious injury could result.

DOC No. 7ZPNA4409
WARNING
Once the hydrostatic release unit (HRU) operates, it cannot be reused. Be careful for capsule so
as not to be stolen or not to be activated by mischief when the ship is in port.
Confirm that the ship's name and ID correspond to those indicated on the label of the capsule
unit.
Rescue work will be planned and executed based on the information of ship's name and ID
transmitted from the capsule unit. Proper planning of rescue work would not be possible if ship's
name and ID are wrong. If the ship's name and ID indicated on the label of the capsule unit is
wrong, ask the purchasing dealer, JRC agent or the JRC branches to change it with correct ship's
name and ID.
If right ID cannot be set in the capsule, do not install the capsule. Otherwise, a large trouble will be
given to the search rescue organization.
Do not install the capsule in an extremely vibrating place such as a handrail. The capsule may be
damaged due to vibration.
Do not install the capsule in a strong magnetic field. The capsule may activate by the magnetic
force.
The capsule must be installed apart from the compass and so for the 0.8 meters or more so that
the magnetism is not influenced.
Mount the capsule on the bracket properly.
Improper mounting causes the capsule not to be automatically released from the bracket in a
sinking.
The battery and hydrostatic release unit (HRU) which expired effective periods expired must not
absolutely be used.
If such battery and HRU are used, the distress signal may not be emitted at the distress. Take
care that their lives do not expire.

DOC No. 7ZPNA4409
WARNING
Do not install with the capsule battery removed. The distress signal may not be emitted at the
distress.
Do not connect the lanyard to the bracket or ship body.
It disturbs at emergency.
When disposing of the capsule, contact the purchasing dealer, JRC agent or JRC branches to
request servicing.
If the capsule is transmitted the distress signal by improper disposal, large confusion is caused in
search and rescue operations.
Do not make the used battery to short-circuit, discharging electricity compulsorily or using for
other usages. Send used batteries to the purchasing dealer, JRC agent or JRC branches.
Do not discard used batteries. Send used batteries to the purchasing dealer, JRC agent or JRC
branches, to avoid causing environmental problem by throwing them away.
When sell the ship, contact to the purchasing dealer, JRC agent or JRC branches, and request to
register the radio station license and reset up the ship's name and ID.
If registration and reset up are not executed, false transmission or wrong ID code signal might be
transmitted in distress, and it causes serious confusion for search and rescue operation.

DOC No. 7ZPNA4409
CAUTION
Open slowly the top cover.
If you open faster, the capsule may deviate from bracket and fall down.
Test the EPIRB function, while anchoring in a port.
In EPIRB function test, permitted distress signal for the test purpose is transmitted. Do not exe-
cute the test repeatedly in a short time.
Execute the test in 00 - 05 minutes of each o'clock for the reduction of processing capacity in the
satellite.
Do not remove, destroy, or modify warning labels.
Request purchasing dealer, JRC agent or JRC branches to replace any stained, illegible, or
damaged label.
If the abnormal status is recognized in the capsule. request the service to purchasing dealer, JRC
agent or JRC branches,
If you want to replace or repair the capsule, contact the purchasing dealer, JRC agent or JRC
branches.
Do not use a solvent (paint-thinner, alcohol etc.) or alkaline/neutral detergent to clean up the
capsule.
It causes crack on the resin if such a detergent is used, and the capsule may not operate properly
in the worst case by leaking etc.

1.1. Outline of the Equipment
This equipment helps investigators identify the causes of marine accidents in order to prevent their recurrence.
The equipment records navigation and hull data, as required by International Standards.
1.2. Feature of New VDR/S-VDR
1) Sensor Data I/F
●Reduction of serial wiring cables is possible by sharing data (LAN: IEC61162-450) with new RA-
DAR/ECDIS.
(For introduction, confirmation for supervisory authorities and ship's classification is required.)
2) Image Data I/F
●Reduction of RGB wiring cable (5 coaxial cables) is possible by connecting to new RADAR/ECDIS
through LAN (IEC61162-450).
3) Capsule I/F
●No separate power cable is required since power is supplied to the capsule unit with the LAN cable.
4) Data recording in capsule units (meet the demands of new standard)
Both the fixed protective capsule unit and the float-free capsule unit store the data recorded for the past 48
hours.
●In VDR (JCY-1900), install both the protective and the float-free. In S-VDR (JCY-1950), install one of
capsules.
●When retrieving the capsule units from the sea, with this 48-hour data recording function, the situation in
the event of an accident can be analyzed by comparing it to that before the accident.
●Addition of the float-free capsule unit makes the retrieval of recording data easier.
5) Data recording in the internal storage (meet the demands of new standard)
The internal storage stores the data recorded for the past 720 hours.
●With this 720-hour recording internal storage, the residual ratio of accident data rises substantially.
●For voyage within 720 hours, all the data during the voyage can be recorded.
6) Audio recording for the bridge
●The 6-track microphone audio function enables recording of conversations in the bridge at 4 places in
addition to the dedicated audio recording in the wing.
●Sound quality is improved (newly designed microphones and re-examined A/D conversion and com-
pression performance).
●Downsized microphone unit and waterproof microphone unit.
7) VHF audio recoding
●The 2-track VHF audio function enables separate recording of No. 1 VHF and No. 2 VHF.
8) RADAR/ECDIS image recording (meet the demands of new standard)
●The 3-screen capacity for image recording enables recording of 3 screens in total (6 channels at max-
imum) for X band RADAR, S band RADAR and ECDIS.
●Recording image alternately for the same units.
9) Performance test (meet the demands of new standard)
●Checking the latest recorded data is available through the Operation Panel Unit..

Standards:
•The 3 screens (X band RADAR, S band RADAR and ECDIS) are recorded every 15 seconds.
* When Rader is standby, the screen is recorded every 20 minutes. (The requirement by the standard
is recording every 10 to 30 minutes.)
•For the same units, screens are recorded alternately.
