4.4.1.2
RANGE Settings
The
RANGE
can be set to suit the circumstances e.g. if a water depth of 35 m is
indicated, the 50 m range will give a better resolution and accuracy than the 200 m
range.
The range can be altered in the same way as the gain, except that here, pressing the
RANGE key
will
decrease
the range and pressing the
RANGE key
will
increase
the range.
There are 6 ranges to choose from, 10, 20, 50, 200, 500 and 2000 m (or the
equivalent in fathoms or feet). Selecting the unit of measurement is described in
chapter 4.5.2.3.
When increasing the range to more than 2000 m scale, an "A" will appear together with
the 200 m scale. "A" indicates the selection of the automatic mode. When the water
depth decreases to a depth less than 50 m, the range will automatically switch to the
50 m range scale; if the water depth increases, the 200 m range will be selected. By
pressing the range keys in the automatic mode, manual control is activated.
When DBS is used, the ranges 0-10 m; 0-20 m are not available, only 0-50 m.
