Chapter 3 Operation Method
(JLN-740A/741A)
The Doppler log must be used strictly as navigation aid equipment only.
The final decision on navigation must be made by the pilot.
If the final decision is made based on the information displayed by the
Doppler log only, an accident such as collision or grounding may occur.
This equipment must not be used by anyone except the ship’s crews and
specialized maintenance staff.
Failure to comply may result in misuse.
Do not carry out operation of touch panel by a sharp object.
Otherwise, the screen may be damaged.
If power outage occurs inside of the ship during the operation of the Doppler
log, the image may be disturbed or may not be displayed.
In this case, reconnect the power supply.
When the power supply is turned off on the display unit, the equipment then
starts when the on-board power supply is turned off/on. This is normal.
If your ship is not on the water such as when it is docked, do not start
transmission. Otherwise, the transducer will be damaged.
