by law to carry on board, and use, the officially published and
approved nautical charts.

1. INTRODUCTION
1.1 The Chartnav 343
The Chartnav 343 is much more than a highly reliable,
innovative chart plotter. It can share and access information
via an NMEA data link. It can quickly step from the chart
screen to three other information packed screens.
The Chartnav 343 on its own is a powerful charting aid.
Add a GPS or other position-finding instrument and the
vessels position and track can be displayed. Add to that an
autopilot and you have an excellent navigation system.
The Chartnav 343 is available with a mono or colour screen.
Figure 1 - System Interactions
1.2 A Word of Caution
You and your analytical abilities are the most important part of
any navigation system. Do not assume that the co-ordinates
you receive from your position-finding instrument are
infallible. Remember also that the Electronic Charts are only as
good as the paper charts they were digitized (copied) from.
The Chartnav 343 is intended as a supplement to standard
paper charts, not a replacement. A prudent navigator always
double-checks his data against other navigational aids, the
safety of your vessel and your crew is at stake.
1.3 For the New Chartnav User
In writing this manual we assume you are familiar with
marine navigation and the use of latitude/longitude co-
ordinates.
Learning how to use the Chartnav is best done before you
find yourself at sea in a heavy fog! Remember your Chartnav
343, and any position-finding device or autopilot must be
installed correctly for safe navigation.

2. USING YOUR CHARTNAV 343
2.1 The Chart Cards
The Chartnav 343 uses the small C-MAP CF95 chart cards.
Each card contains many charts of the area it covers but you
need to ensure that your cards give you suitable coverage at a
suitable scale for your journey.
You can put your chart cards in to either slot in any order.
2.2 Powering up
Press and release the POWER key to turn the Chartnav 343
on. Pressing and holding the POWER key turns the unit off
so be careful not to hold the key in. The unit will power up
and carry out a self-test routine. As the unit runs through this
test, which will take about 15 seconds, you will see the test
results;
System Unit Test The V*.** is the test software version fitted to your unit.
KERNAL 8000 These identify the operating system as Chartnav 343
SYSTEM WORD 0005 85A1 - A C-Map Reference Number.
EPROM TEST When the unit completes the Eprom Test it will display
PASSED. If the unit finds a fault with the Eprom NOT PASSED
will be shown. A Cetrek Distributor should be consulted.
RAM TEST Having checked the hardware the unit completes the RAM
Test by displaying PASSED. Should a serious hardware error
be found the unit will display NOT PASSED and a Cetrek
Distributor should be consulted.
DATA This checks that the cards are functioning correctly and
displays the identification code of the cards. NOT PRESENT
OR FAULTY will be displayed if there are no cards or if the
card is not in the slot properly. FAULTY will be shown if a
reading error has been found, this is normally due to a
damaged card. Should the card contacts become dirty they
are easily cleaned using an ordinary pencil eraser.

CODE This checks that the software is operating correctly and
displays the software version fitted. Should a reading error be
found, FAULTY, will be shown and the system will reset and
repeat the self-test. If FAULTY is displayed again, consult a
Cetrek Distributor.
Once the tests are complete the Cetrek logo is displayed for a
few seconds, this is then replaced with a Caution Page.
CAUTION
CHARTNAV 343’s displays are based on geographical data that C-MAP
believes to be accurate.
However, you should not rely on these visual map displays as your primary
source of navigation.
The CHARTNAV 343 is designed only to ease and speed up navigation
calculations and must not be relied upon exclusively.
Rather, CHARTNAV 343 should be used only as a backup to official
government paper charts and traditional navigational methods.
Displayed charts are only current on the date of issue shown on the chart
card.
