11.4 Lock mode
Whilst in Navigation mode, pressing * for two beeps locks the
YEOMAN in Navigation mode, while still allowing different
modes such as Satellite Info, Range and Bearing, manual
Dead Reckoning, Course, Speed Over Ground and Time To
Go to be accessed.
When in Lock mode the NA flag in the centre of the screen
changes to NL.
Press of * for one beep or a single press of # unlocks the
lock mode.
11.5 Two position referencing
The YEOMAN will operate with only two reference positions by
referencing Positions 1 and 2 normally and then by referencing
Position 3 on the same point as Position 2.
This method of chart referencing allows the use of small charts
and insets where it might be difficult to find three suitable
reference positions. It also enables the creation of a large
scale Mercator plotting sheet.
REFERENCING ON TWO POSITIONS PROVIDES NO
REFERENCING CHECK AND MAY RESULT IN SMALL
INACCURACIES. USE THIS METHOD WITH CAUTION.
