Chapter 3. Cautions with handling
3.1 Cautions while using
If there happens thunder lightning, don’t try to touch the metal part of the power switch.
There is danger of electronic shock by lightning strikes.
Only DC 24V power is available. If it is connected to AC power or not to standard power,
it could cause a fire, an electronic shocks or breakdown of device.
Use the standard fuse. If non-standardized fuse is used while replacement, it will cause
fire and breakdown.
Don't treat the cable forcefully and don’t give a pressure on cable. Damaged cable could
be a cause of a fire and electronic shock.
Don't operate remote, compass and plotter function in case of bad range of vision like in
the harbor tiny water-way, near at obstacles. Unexpected electronic trouble could cause a
collision.
Full attention required around ship and a course Unexpected trouble could cause a
collision.
In case of emergency, shift the operating switch to manual operating mode.
Keep away from water, the steering controller and solenoid valve are not perfectly
waterproof. So it could be cause of fire and electronic shock. When device gets wet, turn
off power supply and input power switch. After that make a check.
Don't turn on engine starter, after connecting power supply. It causes a rapid change of
voltage and improper operation.
Don’t smash remote controller against floor or wall.
3.2 Cautions while installation
3.1.1 Installation for display unit of SAS-70
Don’t mount control amplifier at the place where could cause trouble to drive ship.
Avoid high vibrating places, high temperature, sea water and rain.
Avoid places to be affected by direct rays of the sun.
Make it clear how to shift to manual operating mode against emergency mode.
3.1.2 Installation for direction sensor
Check out if the direction sensor at least 1M away form magnetic objects (tools, speakers
etc.).
If magnetic objects are close, the ships might be twisted owing to change of the heading
bearings’ angle.
Keep away magnetic classified tools from the device.
3.1.3 Installation for Solenoid valve
Install it horizontally. Otherwise, it might be cause troubles.

3.1.4 Installation for Transmitter
Avoid places at high vibration, high temperature, rain and sea-water.
3.1.5 Hydraulic piping
After finishing piping work, clean pipe and around pipe and then disassemble linked part
and do flushing.
Dust and protrusion might be cause troubles.
Only use pipe cutter for cutting and cut it in perpendicular with a cutter.
After completely finished the hydraulic piping, clean the oil tank clearly and change oils.
Put permanent magnet into an oil tank in order to eliminate steel leavings.
3.1.6 Electric Wiring
Work on Power Off. Otherwise, it could cause a short circuit and breakdown.
Connect cable to terminal of device in accordance with installation manual.
Wrong connecting, it could cause breakdown.
Firmly fasten screws and connectors.
Keep away possibly from radio equipment (SSB, VHF etc.).
Keep away cables of Auto Pilot from ones of Radio equipment because it might be
interfered by Radio equipment in accordance with the location of installation.
