1.1 Introduction and system familiarization
Congratulations on your purchase of
SIMRAD CR40/42/50 MKII DGPS
ChartRadar
- a combination of the latest GPS receiver technology and built-in
differential receiver for accurate positioning and prepared for SDGPS, plus:
detailed cartography and high performance radar; all in a unique slim-line design
with a 10” TFT (CR40), a 10” ATFT (CR42), or 14” TFT (CR50) large LCD

The CR40/42/50 MKII chart system
includes a built-in world chart for rough
planning and overview. The choice of chart system best suitable for the
CR40/42/50 MKII was carefully singled out to be the
C-MAP NT mini cards.
The optional C-MAP charts are available world-wide at your local Simrad dealer.
The radar system
with dual EBL and VRM markers, direct Quick-range keys,
off-center mode, etc. together with Dual Radar feature … two radar displays in
one screen, one for short range and one for long distance observations.
The Global Positioning System
is at this time and age the most common
system used for navigation and positioning all over the world. Not only for
maritime use, but also for land-based applications and aviation. The satellite-
based system has been developed and is operated by the US Department of
Defense in order to provide an accurate and reliable service, which include a 24-
hour global coverage.
The GPS system consists of approx. 24 satellites which orbit around the Earth at
an altitude of approx. 20,200 km.
The satellites transmit perfectly synchronized data. However, depending on the
position, the signals will reach the receiver at a slightly different time. By adding
the measured time difference to the known position of the satellites it is possible
to calculate the ship’s position to within a few meters.
DS40/42/50 Dual Station
- remote control unit for the CR40/42/50 is available
in 10” black & white or TFT/ATFT color, or in 14” TFT color.

It is a good idea if you make yourself familiar with the key functions, menu
structure and rotation of pages (screens) described in chapter 2 before you start
