NavStations and Chartplotters

Work-around for heading offset and new software

Error report
A few users of the CX34/44/54 NavStation have experienced that just after the unit is turned on, the radar in Head Up mode at times could have an unexpected offset. The reason to this anomaly has proved to be:

If the unit was switched off with the radar orientation setting left in Course Up mode with compass heading, then:
When turned back on, the radar orientation mode is automatically default to Head Up mode, but the Course Up mode and compass heading would be ‘hanging’ in the memory and therefore create the false heading offset.

The reason why only a few have experienced this anomaly may be because users often have a favorite orientation mode: HU, NU or CU, which they select immediate after the unit is turned on.
And if the same mode is selected at start-up which was active at turn-down, then there will be no false heading offset.

Work-around
The anomaly is overcome simply by changing the radar orientation immediately after the unit is
turned on:
1. Press [ADJ] to open for adjustment.
2. Use the [+] key to toggle the HU/NU/CU
orientations to select the desired setting.

New software
Although Simrad are planning for a software release with settings for the new scanners later this year, they have decided to release version 3.06, which includes a correction of the heading offset anomaly and a few other minor corrections.

Update
The new software version 3.06 is regarded as a minor bug fix and as such customers who have the problem will have this interim software upgrade performed FOC .
