CODE: 7ZPJD0389A

Preface
i
Thank you for buying JRC JCY-1850 Simplified Voyage Data Recorder (S-VDR).
This equipment helps to detect the cause of marine accident to prevent the recurrence in the
future. The equipment records voyage data, as required by the International Standard, during
the navigation and the hull data of the vessel.
•To ensure your S-VDR provide optimum satisfaction and service, read this manual carefully
before attempting to operate the JCY-1850.
•We recommend you to carefully store the manual for future reference.
•If you have any problems using this product, this manual will surely help you.
In order to detect the cause of marine accident, the S-VDR records hull data and navigation
information.
If an accident has occurred, it is mandatory to preserve the record data immediately.
In case an accident has occurred, please preserve the record data according to the procedure
described in 1.4.4: “Actions to be taken at the time of an accident”
To ensure the proper operation, we recommend you to read the procedure carefully.
ATTENTION S-VDR erases older data that has passed for more than 12 hours and
overwrites new one.
Therefore if you do not operate properly, the recorded data at the time of
accident is erased automatically after 12 hours.

Before Operation
v
Do not remove, damage, or alter the labels attached to the equipment.
Do not install the equipment, if the location is infringed by water, humid, dusty, or
with soot.
Ignoring the caution may result in a fire, an electric shock, or a malfunction.
Hands off the equipment if your hand or glove is wet either with freshwater or
seawater.
Ignoring the caution may result in a fire, an electric shock, or a fault.
Be sure to hold the power supply plug when pulling it out from the outlet.
Pulling the electric cable without holding the plug could damage the cable,
resulting in a fire or an electric shock.
Do not remove or insert the power supply plug with wet hand.
Ignoring the caution may result in an electric shock.
Although the UTILITY OUTLET looks like the one of AC100V, the input voltage of
the Recording Control Unit directly comes out from it.
i.e; In case the 220VAC is supplied, the same voltage comes out from UTILITY
OUTLET. Ignoring the caution may result in failures.
If the FAN ABNORMAL LED lights up, either of the two fans of the Power Supply
Unit is out of order and needs to be replaced. Ignoring the caution may result in
failures. Contact the Sales Department, the nearest branch company, branch
office, sales office, or any agent of Japan Radio Co., Ltd. and ask them to replace it.
If the equipment is splashed either with seawater or fresh water, wipe it dry
immediately. Ignoring the caution may result in failures or operational
malfunctions.
Do not use organic solvent such as thinner or benzine to clean the surface. These
agents damage the surface coating.
Be sure to remove dirt and dust, if any, from the surface and wipe it with a clean
dry cloth.
