Overview; Cleaning And Maintenance - Navman Datahelm 8120 Installation And Operation Manual

1-1 Overview

The NAVMAN 8120 is a rugged, highly
integrated marine chartplotter and fishfinder.
It is easy to use and has a very large, easy
to read and use colour display. Complex
functions can be performed with only a few
key presses, taking the hard work out of
boating.
The available functions depend on the
optional sensors and instruments that are
installed:
The Video window requires the 8120 to
receive video from a compatible source,
such as a camera.
Fuel functions require one or more
petrol/gasoline or diesel fuel sensors to be
installed.
SmartCraft engine functions require a
SmartCraft system to be installed. For
information on using SmartCraft, see
the SmartCraft Gateway Installation and
Operation Manual.

1-2 Cleaning and maintenance

The Instrument screen is covered by a
proprietary anti-reflection coating. To avoid
damage, clean the screen only with a damp
cloth and mild detergent when dirty or
covered in sea salt. Avoid abrasive cleaners,
petrol or other solvents. If a plug-in card gets
dirty or wet, clean it with a damp cloth or
mild detergent.
Cover or remove a transom-mounted
transducer when repainting the hull. If
painting over a through hull transducer with
antifouling paint, use only one coat of paint.
Remove the previous coat of antifouling paint
by sanding it lightly.
6
DSC/Buddy track functions require an
appropriate Navman DSC VHF radio to be
installed.
The 8120 can send data to other
instruments, such as an autopilot, and
receive data from other instruments.
For information on installation options, see
section 18-2.
This manual describes how to install and
operate the 8120. Special terms are explained
in Appendix C. For more information on this
instrument and other Navman products, go

To optimize performance, avoid walking on
or jamming cables and connectors. Keep the
transducer free of weed, paint and debris.
Do not use a high pressure water blast on a
speed sensor paddlewheel as it may damage
the bearings.
Push the dust cover over the display when
the Instrument is turned off.
